'''Arrocane Arlene''' was a catastrophic and historic tropical cyclone—the most powerful arrocane ever recorded in the Ardonia basin. Forming in mid-May 2019, the storm became the earliest Category 5 arrocane on record and eventually broke over a dozen all-time records for intensity, windspeed, rainfall, and storm surge. Arlene reached peak sustained winds of 180 mph (290 km/h) and a central pressure of 899 mbar, the strongest and most intense values ever observed in the basin.
'''Arrocane Arlene''' was a catastrophic and historic tropical cyclone—the most powerful arrocane ever recorded in the '''Ardonia basin'''. Forming in mid-May 2019, the storm rapidly intensified into the earliest '''Category 5 arrocane''' on record, ultimately breaking over a dozen basin-wide records for intensity, windspeed, rainfall, storm surge, and landfall strength. Arlene reached a peak intensity of '''180 mph (290 km/h)''' sustained winds and a central pressure of '''899 mbar''', making it the strongest arrocane ever observed in the region.


Arlene made three destructive landfalls in Cydonia—first in Po'Hatu at Category 5 intensity, then in Meridian as a Category 4, and finally in Port Kazu as a Category 3. The storm caused catastrophic damage and deadly flooding as it stalled over the region. In total, Arlene left 113 people dead, over 2,500 injured, and at least $24.9 billion AC in damages. Due to its historic impact, the name "Arlene" was retired following the season.
Arlene's path through the heart of the '''Gulf of Ardonia''' brought it directly toward the kingdom of '''Cydonia''', where it made '''three destructive landfalls''' in rapid succession. The first struck the small island of '''Po'Hatu''' at Category 5 intensity, followed by a Category 4 landfall in the capital city of '''Meridian'''. Arlene then curved northeastward and made a third landfall in '''Port Kazu''' as a Category 3 arrocane, where it stalled for over 24 hours at Tropical Storm intensity, unleashing devastating flooding and storm surge. The prolonged assault on the city was one of the worst weather-related disasters in '''Ardonian''' history.
 
The storm left a trail of devastation across multiple regions including '''Blade Island''', '''Kaeru''', '''Phaethon''', and the '''Ardidia Cliffs''', and was responsible for the deaths of '''1,379 people''', more than '''15,000 injuries''', and approximately '''$158 billion AC''' in damage. Nearly every meteorological, infrastructural, and humanitarian threshold was surpassed during Arlene’s lifespan. The storm has been widely regarded as a defining event in '''Ardonian meteorological history''', prompting widespread review of forecasting protocols, emergency response coordination, and disaster management frameworks.
 
While the '''Ardonia Meteorological Organization (AMO)''' has not yet formally retired the name '''Arlene''', the agency has listed it as a '''100% retirement likelihood''' candidate pending end-of-season review.

'''Arrocane Arlene''' originated from a broad area of low pressure in the southern '''Gulf of Ardonia''' on May 17. Favorable environmental conditions—including abnormally warm sea surface temperatures, deep oceanic heat content, high mid-level humidity, and low wind shear—allowed the disturbance to gradually consolidate. The system developed a well-defined low-level circulation overnight and was designated as '''One-A''' by the '''National Arrocane Center (NAC)''' on May 18. Within 6 hours, it intensified into Tropical Storm '''Arlene''' as banding features began to organize around its center.
Steered slowly northwestward by a mid-level ridge over central Ardonia, Arlene traversed an area of record-warm waters in the '''Gulf of Ardonia''' and continued to strengthen steadily. By May 20, it had reached '''Category 1''' intensity and developed a central dense overcast and a small, ragged eye. Over the next 48 hours, the storm entered a period of explosive intensification. Arlene progressed rapidly through Categories 2, 3, and 4, ultimately achieving '''Category 5''' status on May 21. At its peak, the storm exhibited an exceptionally compact and symmetric structure, with a distinct eye only '''4.4 miles''' in diameter and sustained winds of '''180 mph (290 km/h)''' alongside a minimum central pressure of '''899 mbar'''—making it the strongest arrocane ever recorded in the Ardonia basin.

Arlene made its first landfall on May 21 in '''Po'Hatu, Cydonia''' as a high-end Category 5 arrocane, with sustained winds of '''175 mph''' and a pressure of '''908 mbar'''. Despite the island’s small size, it was devastated by the direct hit. Several villages were flattened, and vegetation was shredded across the entire landmass. Just hours later, Arlene made a second landfall in the metropolitan center of '''Meridian''' at Category 4 strength, with winds of '''155 mph''' and a pressure of '''931 mbar'''. The storm's intense core caused widespread wind damage, uprooting trees, damaging infrastructure, and compromising major coastal defenses.
 
After crossing over land, Arlene weakened slightly but retained significant strength. It made a third landfall at '''Port Kazu''' as a Category 3 arrocane with '''115 mph''' winds and a pressure of '''976 mbar'''. Upon landfall, the storm slowed dramatically and began to stall just inland, producing extreme rainfall and storm surge across the region for more than 24 hours. The prolonged interaction with the coast and nearby terrain caused severe flooding and infrastructure collapse throughout the city and surrounding areas.


Arrocane Arlene originated from a broad area of low pressure in the southern Gulf of Ardonia on May 16. Favorable environmental conditions—including abnormally warm sea surface temperatures and low wind shear—allowed the disturbance to gradually consolidate. It was declared a tropical depression by the NAC on May 17 and quickly intensified into Tropical Storm Arlene later that day.
Arlene retained tropical storm strength for nearly two additional days as it meandered inland over eastern '''Cydonia'''. It gradually weakened while maintaining a well-defined core structure, thanks to strong upper-level divergence and persistent moisture inflow. The system transitioned into an extratropical cyclone on May 27 and ultimately dissipated over the eastern Ardonian Ocean on May 30 after losing all tropical characteristics.


By May 18, Arlene had reached Category 1 intensity and began a period of explosive intensification. Over the next 48 hours, the storm progressed through multiple intensity categories, achieving Category 5 status on May 20 with sustained winds of 180 mph (290 km/h) and a central pressure of 899 mbar—making it the most intense and strongest arrocane ever recorded in the Ardonia basin.
==Preparations==
Ahead of Arlene's landfall, the '''National Arrocane Center (NAC)''' and '''NWS Port Kazu''' issued the highest possible alerts across southern Cydonia, the Trinity Islands, and the eastern Gulf coastline. A basin-wide '''''Level V Arrocane Emergency Declaration''''' was enacted for the first time since 2008. Arrocane watches and warnings were issued up to 72 hours in advance for the entire southeastern quadrant of Ardonia, with special advisories targeting densely populated zones and flood-prone coastal districts.


Arlene made its first landfall on May 22 in '''Po'Hatu, Cydonia''' as a high-end Category 5 arrocane, with sustained winds of '''175 mph''' and a pressure of '''908 mbar'''. Despite its small size, the island sustained widespread devastation. Hours later, the storm made a second landfall in '''Meridian''' at Category 4 strength with winds of '''155 mph''' and a pressure of '''931 mbar'''. Arlene weakened slightly before striking '''Port Kazu''' as a Category 3 with '''115 mph''' winds and a pressure of '''976 mbar'''. The storm then stalled over the city as a strong tropical storm, unleashing catastrophic flooding and storm surge across the area.
Mandatory evacuations were ordered for the Trinity Islands, Po’Hatu, Meridian, Crescent Beach, and parts of Blade Island. Over 600,000 residents were urged to relocate inland, and transportation officials temporarily suspended tolls and fare collection on highways, rail systems, and ferry routes to expedite evacuation efforts. Shelters were activated in school buildings, civic centers, and fortified underground bunkers in Sendaria and Kaltaria.


Arlene retained tropical storm strength for nearly two more days as it drifted inland and across central Cydonia, before weakening and eventually becoming extratropical on May 27. The system finally dissipated over the northern Gulf of Ardonia on May 30.
The NAC coordinated with local authorities and the Cydonian Royal Guard to stage relief convoys, distribute sandbags, and position water rescue units in flood-vulnerable areas. Over 3,500 troops were placed on standby under the command of the Southern Response Corps, with assets staged in Fort Braymin and Crown Peak for logistical backup. Naval patrols were deployed along the Gulf of Ardonia to assist with offshore monitoring and early search-and-rescue readiness.


==Preparations==
Power companies preemptively shut down vulnerable grid sections along coastal corridors to avoid electrocution hazards, and medical facilities were supplied with emergency fuel for backup generators. The Ardonian Weather Relay (AWR) broadcast continuous live coverage, with multilingual updates issued across all provinces to reach rural and isolated communities.
Ahead of Arlene's landfall, the National Arrocane Center and NWS Port Kazu issued the highest possible alerts across southern Cydonia and nearby coastal regions. Mandatory evacuations were ordered for the Trinity Islands, Po’Hatu, and Meridian, while emergency shelters were established inland. The NAC coordinated with local authorities to deploy response teams, and military forces were placed on standby throughout the region.
 
Local governments also activated pre-arranged agreements with private shipping companies to secure food reserves, emergency medical kits, and mobile field hospitals. In Kaeru and Phaethon, floodgates and sea barriers were reinforced with additional concrete sheeting hours before landfall. These coordinated actions were credited with preventing an even higher death toll, despite the unprecedented strength of Arlene.

Arlene caused catastrophic damage across wide swaths of Ardonia. The worst devastation occurred in Cydonia, where entire towns were flattened, and massive coastal flooding occurred due to storm surge peaking at '''50.75 ft'''. Rainfall totals reached a staggering '''250.59 inches''' in localized areas, and the highest recorded wave height of '''99.3 feet''' was observed off the coast of Kaeru.
Arlene caused catastrophic damage across wide swaths of Ardonia, with its impacts felt from the outer Trinity Islands to the mountainous interior of Cydonia. The worst devastation occurred in southern Cydonia, where entire towns were flattened by extreme winds, storm surge, and flash flooding. Coastal inundation reached unprecedented levels, with surge heights peaking at '''50.75 ft''' in low-lying areas, submerging entire districts of Port Kazu.
 
Rainfall totals shattered all previous records, with localized measurements of up to '''250.59 inches'''—causing widespread river flooding, landslides, and the total collapse of transportation networks. Along the eastern coast, Kaeru experienced the highest confirmed wave height ever recorded in the basin at '''99.3 ft''', severely damaging port infrastructure and rendering harbors unusable.
 
In '''Po’Hatu''', the first point of landfall, most structures were destroyed or swept away, leaving the island nearly uninhabitable. '''Meridian''', struck next, suffered extreme wind damage to high-rise buildings and historical sites, along with widespread loss of communications and utilities. The most prolonged and devastating impact occurred in '''Port Kazu''', where the storm stalled and dropped relentless rainfall over several days. The city’s flood defenses were overwhelmed, resulting in submerged metro systems, collapsed bridges, and large-scale displacement.
 
In total, Arlene caused approximately '''$158 billion AC''' in damage, making it the costliest arrocane in Ardonian history. The storm killed '''1,379 people''' and left over '''15,000 injured''', with '''32 individuals''' still unaccounted for as of the latest reports. Over '''450,000 people''' were displaced from their homes, and thousands required long-term shelter assistance. Blade Island and the Ardidia Cliffs region reported severe erosion and infrastructure collapse due to wave action and ground saturation.
 
Critical industries across Cydonia—including mining, agriculture, and shipping—sustained long-term disruption. Crop losses in the '''Phaethon lowlands''' were described as near-total, raising food security concerns in surrounding provinces. Emergency airlifts were required to reach isolated communities in the Trinity Islands and Crescent Beach, where roads were rendered impassable.


In total, Arlene caused at least '''$24.9 billion AC''' in damage, making it the costliest arrocane in Ardonian history. The storm killed '''113 people''' and left over '''2,500 injured''', with '''32 individuals''' still unaccounted for. Infrastructure in Meridian, Port Kazu, and Blade Island was heavily damaged or destroyed, and agricultural losses in the Phaethon lowlands were described as near-total.
Multiple regional airports, including the main terminal in Meridian, were forced to close due to flooding and wind damage, hampering evacuation and relief logistics. Total insured and uninsured losses are expected to rise in subsequent assessments, with damage reports still being compiled by local NWS offices and NAC field teams.


==Aftermath==
==Aftermath==
In the storm’s aftermath, large-scale rescue and recovery efforts were launched by the NAC, regional governments, and international aid organizations. Emergency supplies were airlifted to isolated areas, while engineers worked to restore power and reopen vital roadways. The government of Cydonia declared a state of emergency, and long-term rebuilding efforts were projected to take multiple years.
In the storm’s aftermath, large-scale rescue and recovery operations were mobilized by the '''National Arrocane Center (NAC)''', regional governments, and international aid organizations. Emergency supplies were airlifted to the hardest-hit areas, including Po’Hatu and Crescent Beach, which were completely cut off by floodwaters and debris. Dozens of temporary shelters were established across southern Cydonia, where over 350,000 residents had been displaced.
 
Infrastructure repair efforts began immediately, but progress was hampered by washed-out roads, collapsed bridges, and prolonged power outages. Port Kazu’s metro and power grid were reported to be “non-functional,” while telecommunications remained limited for days across the Ardidia Cliffs and Kaeru. Engineers from across Ardonia were dispatched to assist in restoring electricity and clearing critical highways, with a focus on reestablishing medical and supply routes.


Due to its unprecedented strength and devastating impact, the name "Arlene" was officially retired from the naming lists. In the months following the storm, meteorological agencies began reevaluating rapid intensification protocols and landfall response strategies, marking Arlene as a defining event in the history of Ardonia's meteorology.
The government of Cydonia declared a state of emergency for the entire southern half of the kingdom, triggering the deployment of national guards and disaster relief reserves. Foreign assistance arrived from nearby kingdoms, including K’arthen and Conchord, delivering food, water, and fuel via both air and sea.
 
Educational institutions in affected areas were closed indefinitely, with some schools converted into emergency shelters or relief coordination centers. Damage to agricultural regions, especially in the Phaethon lowlands, raised concerns about long-term food supply stability and economic recovery. In total, over 1.2 million residents across Ardonia were estimated to have been directly impacted by the storm’s effects.
 
The '''Ardonia Meteorological Organization (AMO)''' began reviewing the storm’s performance shortly after its dissipation. While official retirement of the name "Arlene" has not yet occurred, the AMO has placed it under active consideration, currently listing the retirement likelihood at '''100%'''. A final decision is expected at the conclusion of the season, following a full post-season analysis and regional consultation.
 
In the months following Arlene, the NAC and AMO jointly initiated efforts to improve storm surge forecasting, rapid intensification detection, and urban flood response coordination. The event is widely considered one of the most significant in the basin’s history, likely to influence arrocane policy and disaster preparedness for years to come.

Part of the 2019 Ardonia arrocane season

Arrocane Arlene was a catastrophic and historic tropical cyclone—the most powerful arrocane ever recorded in the Ardonia basin. Forming in mid-May 2019, the storm rapidly intensified into the earliest Category 5 arrocane on record, ultimately breaking over a dozen basin-wide records for intensity, windspeed, rainfall, storm surge, and landfall strength. Arlene reached a peak intensity of 180 mph (290 km/h) sustained winds and a central pressure of 899 mbar, making it the strongest arrocane ever observed in the region.

Arlene's path through the heart of the Gulf of Ardonia brought it directly toward the kingdom of Cydonia, where it made three destructive landfalls in rapid succession. The first struck the small island of Po'Hatu at Category 5 intensity, followed by a Category 4 landfall in the capital city of Meridian. Arlene then curved northeastward and made a third landfall in Port Kazu as a Category 3 arrocane, where it stalled for over 24 hours at Tropical Storm intensity, unleashing devastating flooding and storm surge. The prolonged assault on the city was one of the worst weather-related disasters in Ardonian history.

The storm left a trail of devastation across multiple regions including Blade Island, Kaeru, Phaethon, and the Ardidia Cliffs, and was responsible for the deaths of 1,379 people, more than 15,000 injuries, and approximately $158 billion AC in damage. Nearly every meteorological, infrastructural, and humanitarian threshold was surpassed during Arlene’s lifespan. The storm has been widely regarded as a defining event in Ardonian meteorological history, prompting widespread review of forecasting protocols, emergency response coordination, and disaster management frameworks.

While the Ardonia Meteorological Organization (AMO) has not yet formally retired the name Arlene, the agency has listed it as a 100% retirement likelihood candidate pending end-of-season review.

Arrocane Arlene originated from a broad area of low pressure in the southern Gulf of Ardonia on May 17. Favorable environmental conditions—including abnormally warm sea surface temperatures, deep oceanic heat content, high mid-level humidity, and low wind shear—allowed the disturbance to gradually consolidate. The system developed a well-defined low-level circulation overnight and was designated as One-A by the National Arrocane Center (NAC) on May 18. Within 6 hours, it intensified into Tropical Storm Arlene as banding features began to organize around its center.

Steered slowly northwestward by a mid-level ridge over central Ardonia, Arlene traversed an area of record-warm waters in the Gulf of Ardonia and continued to strengthen steadily. By May 20, it had reached Category 1 intensity and developed a central dense overcast and a small, ragged eye. Over the next 48 hours, the storm entered a period of explosive intensification. Arlene progressed rapidly through Categories 2, 3, and 4, ultimately achieving Category 5 status on May 21. At its peak, the storm exhibited an exceptionally compact and symmetric structure, with a distinct eye only 4.4 miles in diameter and sustained winds of 180 mph (290 km/h) alongside a minimum central pressure of 899 mbar—making it the strongest arrocane ever recorded in the Ardonia basin.

Arlene making it's record breaking landfall in Po'Hatu, Cydonia.

Arlene made its first landfall on May 21 in Po'Hatu, Cydonia as a high-end Category 5 arrocane, with sustained winds of 175 mph and a pressure of 908 mbar. Despite the island’s small size, it was devastated by the direct hit. Several villages were flattened, and vegetation was shredded across the entire landmass. Just hours later, Arlene made a second landfall in the metropolitan center of Meridian at Category 4 strength, with winds of 155 mph and a pressure of 931 mbar. The storm's intense core caused widespread wind damage, uprooting trees, damaging infrastructure, and compromising major coastal defenses.

After crossing over land, Arlene weakened slightly but retained significant strength. It made a third landfall at Port Kazu as a Category 3 arrocane with 115 mph winds and a pressure of 976 mbar. Upon landfall, the storm slowed dramatically and began to stall just inland, producing extreme rainfall and storm surge across the region for more than 24 hours. The prolonged interaction with the coast and nearby terrain caused severe flooding and infrastructure collapse throughout the city and surrounding areas.

Arlene retained tropical storm strength for nearly two additional days as it meandered inland over eastern Cydonia. It gradually weakened while maintaining a well-defined core structure, thanks to strong upper-level divergence and persistent moisture inflow. The system transitioned into an extratropical cyclone on May 27 and ultimately dissipated over the eastern Ardonian Ocean on May 30 after losing all tropical characteristics.

Preparations

Ahead of Arlene's landfall, the National Arrocane Center (NAC) and NWS Port Kazu issued the highest possible alerts across southern Cydonia, the Trinity Islands, and the eastern Gulf coastline. A basin-wide Level V Arrocane Emergency Declaration was enacted for the first time since 2008. Arrocane watches and warnings were issued up to 72 hours in advance for the entire southeastern quadrant of Ardonia, with special advisories targeting densely populated zones and flood-prone coastal districts.

Mandatory evacuations were ordered for the Trinity Islands, Po’Hatu, Meridian, Crescent Beach, and parts of Blade Island. Over 600,000 residents were urged to relocate inland, and transportation officials temporarily suspended tolls and fare collection on highways, rail systems, and ferry routes to expedite evacuation efforts. Shelters were activated in school buildings, civic centers, and fortified underground bunkers in Sendaria and Kaltaria.

The NAC coordinated with local authorities and the Cydonian Royal Guard to stage relief convoys, distribute sandbags, and position water rescue units in flood-vulnerable areas. Over 3,500 troops were placed on standby under the command of the Southern Response Corps, with assets staged in Fort Braymin and Crown Peak for logistical backup. Naval patrols were deployed along the Gulf of Ardonia to assist with offshore monitoring and early search-and-rescue readiness.

Power companies preemptively shut down vulnerable grid sections along coastal corridors to avoid electrocution hazards, and medical facilities were supplied with emergency fuel for backup generators. The Ardonian Weather Relay (AWR) broadcast continuous live coverage, with multilingual updates issued across all provinces to reach rural and isolated communities.

Local governments also activated pre-arranged agreements with private shipping companies to secure food reserves, emergency medical kits, and mobile field hospitals. In Kaeru and Phaethon, floodgates and sea barriers were reinforced with additional concrete sheeting hours before landfall. These coordinated actions were credited with preventing an even higher death toll, despite the unprecedented strength of Arlene.

Arlene caused catastrophic damage across wide swaths of Ardonia, with its impacts felt from the outer Trinity Islands to the mountainous interior of Cydonia. The worst devastation occurred in southern Cydonia, where entire towns were flattened by extreme winds, storm surge, and flash flooding. Coastal inundation reached unprecedented levels, with surge heights peaking at 50.75 ft in low-lying areas, submerging entire districts of Port Kazu.

Rainfall totals shattered all previous records, with localized measurements of up to 250.59 inches—causing widespread river flooding, landslides, and the total collapse of transportation networks. Along the eastern coast, Kaeru experienced the highest confirmed wave height ever recorded in the basin at 99.3 ft, severely damaging port infrastructure and rendering harbors unusable.

In Po’Hatu, the first point of landfall, most structures were destroyed or swept away, leaving the island nearly uninhabitable. Meridian, struck next, suffered extreme wind damage to high-rise buildings and historical sites, along with widespread loss of communications and utilities. The most prolonged and devastating impact occurred in Port Kazu, where the storm stalled and dropped relentless rainfall over several days. The city’s flood defenses were overwhelmed, resulting in submerged metro systems, collapsed bridges, and large-scale displacement.

In total, Arlene caused approximately $158 billion AC in damage, making it the costliest arrocane in Ardonian history. The storm killed 1,379 people and left over 15,000 injured, with 32 individuals still unaccounted for as of the latest reports. Over 450,000 people were displaced from their homes, and thousands required long-term shelter assistance. Blade Island and the Ardidia Cliffs region reported severe erosion and infrastructure collapse due to wave action and ground saturation.

Critical industries across Cydonia—including mining, agriculture, and shipping—sustained long-term disruption. Crop losses in the Phaethon lowlands were described as near-total, raising food security concerns in surrounding provinces. Emergency airlifts were required to reach isolated communities in the Trinity Islands and Crescent Beach, where roads were rendered impassable.

Multiple regional airports, including the main terminal in Meridian, were forced to close due to flooding and wind damage, hampering evacuation and relief logistics. Total insured and uninsured losses are expected to rise in subsequent assessments, with damage reports still being compiled by local NWS offices and NAC field teams.

Aftermath

In the storm’s aftermath, large-scale rescue and recovery operations were mobilized by the National Arrocane Center (NAC), regional governments, and international aid organizations. Emergency supplies were airlifted to the hardest-hit areas, including Po’Hatu and Crescent Beach, which were completely cut off by floodwaters and debris. Dozens of temporary shelters were established across southern Cydonia, where over 350,000 residents had been displaced.

Infrastructure repair efforts began immediately, but progress was hampered by washed-out roads, collapsed bridges, and prolonged power outages. Port Kazu’s metro and power grid were reported to be “non-functional,” while telecommunications remained limited for days across the Ardidia Cliffs and Kaeru. Engineers from across Ardonia were dispatched to assist in restoring electricity and clearing critical highways, with a focus on reestablishing medical and supply routes.

The government of Cydonia declared a state of emergency for the entire southern half of the kingdom, triggering the deployment of national guards and disaster relief reserves. Foreign assistance arrived from nearby kingdoms, including K’arthen and Conchord, delivering food, water, and fuel via both air and sea.

Educational institutions in affected areas were closed indefinitely, with some schools converted into emergency shelters or relief coordination centers. Damage to agricultural regions, especially in the Phaethon lowlands, raised concerns about long-term food supply stability and economic recovery. In total, over 1.2 million residents across Ardonia were estimated to have been directly impacted by the storm’s effects.

The Ardonia Meteorological Organization (AMO) began reviewing the storm’s performance shortly after its dissipation. While official retirement of the name "Arlene" has not yet occurred, the AMO has placed it under active consideration, currently listing the retirement likelihood at 100%. A final decision is expected at the conclusion of the season, following a full post-season analysis and regional consultation.

In the months following Arlene, the NAC and AMO jointly initiated efforts to improve storm surge forecasting, rapid intensification detection, and urban flood response coordination. The event is widely considered one of the most significant in the basin’s history, likely to influence arrocane policy and disaster preparedness for years to come.
