How do you categorize a hurricane?
Hurricanes are categorized on a scale of one through five using the Saffir-Simpson scale, which is based on sustained wind speed:
- Category 1: 74-95 mph.
- Category 2: 96-110 mph.
- Category 3: 111-129 mph.
- Category 4: 130-156 mph.
- Category 5: 157+ mph.
How are hurricanes measured and put into categories?
The intensity of a hurricane is measured by the Saffir-Simpson Hurricane Wind Scale. This rates the storms from one to five based on sustained wind speed and the potential property damage those winds can cause. The intensity of a hurricane is measured by the Saffir-Simpson Hurricane Wind Scale.
What’s a Category 4 hurricane?
On the Saffir-Simpson Hurricane Wind Scale, a Category 4 hurricane has winds of 130 mph to 156 mph. Category 4 winds will cause catastrophic damage, hurricane forecasters said, such as: – Well-built homes can sustain severe damage with the loss of most of the roof structure and/or some exterior walls.

What’s a Category 3 hurricane?
Category Three Hurricane. Winds 111-129 mph (96-112 kt or 178-208 km/hr). Devastating damage will occur: Well-built framed homes may incur major damage or removal of roof decking and gable ends. Many trees will be snapped or uprooted, blocking numerous roads.

How are hurricanes measured what does the scale mean?
The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane’s sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage.
Has a Category 5 hurricane ever hit the US?
Hurricane Camille, 1969 17 it made landfall as a Category 5 storm along the Mississippi coast. The NHC says the exact wind speed of Camille may never be known since it destroyed all the wind-recording instruments in the area where it made landfall.
