The scale separates hurricanes into five different categories based on wind. The U.S. National Hurricane Center classifies hurricanes of Category 3 and above as
major hurricanes (although all hurricanes can be very dangerous).
Category 1
Category 1 Sustained winds 33–42 m/s 64–82 kn
Hurricane Lester near landfall 119–153 km/h 74–95 mph Normal central pressure 980–994 mbar 28.94 inHg
Very dangerous winds will produce some damage
Category 1 storms usually cause no significant structural damage to most well-constructed permanent structures; however, they can topple unanchored mobile homes, as well as uproot or snap numerous trees. Poorly attached roof shingles or tiles can blow off. Coastal flooding and pier damage are often associated with Category 1 storms. Power outages are typically widespread to extensive, sometimes lasting several days. Even though it is the least intense type of hurricane, the storm can still produce widespread damage and can be a life-threatening storm.
Category 2
Extremely dangerous winds will cause extensive damage
Category 3
Devastating damage will occur
Category 4
Horrific damage will occur
Category 5
Catastrophic damage will occur
