Familiarize yourself with the terms that are used to identify a hurricane.

  • A hurricane watch means a hurricane is possible in your area. Be prepared to evacuate. Monitor local radio and television news outlets or listen to NOAA Weather Radio for the latest developments.
  • A hurricane warning is when a hurricane is expected in your area. If local authorities advise you to evacuate, leave immediately.
  • Hurricanes are classified into five categories based on their wind speed, central pressure, and damage potential. Category Three and higher hurricanes are considered major hurricanes, though Categories One and Two are still extremely dangerous and warrant your full attention.
Saffir-Simpson Hurricane Scale
Scale Number (Category)Sustained Winds (MPH)DamageStorm Surge
1 74-95 Minimal: Unanchored mobile homes, vegetation and signs. 4-5 feet
2 96-110 Moderate: All mobile homes, roofs, small crafts, flooding. 6-8 feet
3 111-130 Extensive: Small buildings, low-lying roads cut off. 9-12 feet
4 131-155 Extreme: Roofs destroyed, trees down, roads cut off, mobile homes destroyed. Beach homes flooded. 13-18 feet
5 More than 155 Catastrophic: Most buildings destroyed. Vegetation destroyed. Major roads cut off. Homes flooded. Greater than 18 feet

 

Hurricanes can produce widespread torrential rains. Floods are the deadly and destructive result. Slow moving storms and tropical storms moving into mountainous regions tend to produce especially heavy rain. Excessive rain can trigger landslides or mud slides, especially in mountainous regions. Flash flooding can occur due to intense rainfall. Flooding on rivers and streams may persist for several days or more after the storm.
