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. The Joint Typhoon Warning Center classifies typhoons of 150 mph (240 km/h) or greater (strong Category 4 and Category 5) as super typhoons.
A Category 4 hurricane has winds of 113 to 136 kn (130 to 157 mph; 209 to 252 km/h), while a Category 5 hurricane has winds of at least 137 kn (158 mph; 254 km/h). [1] [3] A post tropical cyclone is a system that has weakened, into a remnant low or has dissipated and formal advisories are usually discontinued at this stage. [1]
Hurricane warning HUW – Hurricane conditions (sustained winds of 64 knots [74 mph; 119 km/h] or greater) are expected within the specified coastal or inland area within 36 hours in advance of the forecast onset of tropical-storm-force winds. A Hurricane Warning can remain in effect if dangerously high storm surge, or a combination of ...
Hurricanes in categories 3, 4 and 5 are considered major hurricanes due to their potential for significant loss of life and damage. Even Category 1 hurricanes can be dangerous and require preparation.
Still, the National Hurricane Center uses categories – set by sustained wind speed – to estimate possible property damage from hurricanes. Here’s what’s expected in each: Category 1: 74-95 mph
The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane's maximum sustained wind speed.Here's how it breaks down. Hurricane Classifications: What do the categories ...
The Saffir-Simpson Hurricane Wind Scale rates hurricanes from one to five. Category 1 hurricanes range from 74 to 95 mph and can bring very dangerous winds that can damage even sturdy houses. Category 1 is the weakest hurricane, and the storms strengthen up the scale from there. If a hurricane is Category 3 or higher, it is considered a major ...
A designation used by the National Hurricane Center reserved for hurricanes in the Atlantic or Northeast Pacific basins that achieve Category 3 in the Saffir–Simpson Hurricane Scale. These storms have winds of at least 96 knots (178 km/h; 110 mph). [9] [1] Maximum Sustained Surface Wind The standard measure of a tropical cyclone's intensity.
