Saffir-Simpson Hurricane Wind Scale

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 categorization based on the hurricane's intensity.

  • Category 1: wind speed of 74-95 mph; very dangerous winds will produce some damage
  • Category 2: wind speed of 96-110 mph; extremely dangerous winds will cause extensive damage
  • Category 3: wind speed of 111-129 mph; devastating damage will occur
  • Category 4: wind speed of 130-156 mph; catastrophic damage will occur

Hurricane watch

A hurricane watch is an announcement that sustained winds of 74 mph or higher are possible. A watch is issued about 48 hours before a storm is expected to reach tropical storm force, because preparations are difficult once that happens.

Landfall

When meteorologists say a hurricane will make landfall soon, they are talking about when the eye of the storm meets the coastline.

Major hurricane

A hurricane that is classified as Category 3 or higher.

Storm surge

An abnormal rise in sea level accompanying a hurricane or other intense storm. Storm surge is usually estimated by subtracting the normal or astronomic high tide from the observed storm tide.
