Ardonia arrocane wind scale
The Ardonia arrocane wind scale (AAWS) classifies arrocanes—which are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds.
| Category | Wind speeds
(1-min sustained winds) | |||
|---|---|---|---|---|
| m/s | knots (kn) | mph | km/h | |
| Category 5 major arrocane | ≥ 72 m/s | ≥ 140 kn | ≥ 160 mph | ≥ 260 km/h |
| Category 4 major arrocane | 58-71 m/s | 110-139 kn | 130-159 mph | 210-259 km/h |
| Category 3 major arrocane | 51-57 m/s | 100-109 kn | 115-129 mph | 185-209 km/h |
| Category 2 arrocane | 42-50 m/s | 83-99 kn | 95-114 mph | 153-184 km/h |
| Category 1 arrocane | 34-41 m/s | 65-82 kn | 75-94 mph | 121-152 km/h |
| Tropical Storm | 18-33 m/s | 35-64 kn | 40-74 mph | 64-120 km/h |
| Tropical Depression | ≤ 17 m/s | ≤ 34 kn | ≤ 39 mph | ≤ 63 km/h |
