Hurricane Wind Scale

Hurricanes are considered the most violent storms on earth because they can encompass many other types of inclement weather, such as powerful thunderstorms, heavy rain that can lead to flooding, tornadoes and wind gusts of over 100 mph. The official hurricane season lasts from June 1st to November 30th, but the greatest chance of a hurricane landfall for Texas is during August and September.

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane’s sustained wind speed:

Category 1

-

Winds 75 to 95 mph

Very dangerous winds

Well-constructed frame homes could have damage to roof, shingles and gutters. Large branches of trees will snap and shallowly rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days.

Category 2

-

Winds 96 to 110 mph

Extremely dangerous winds

Well-constructed frame homes could sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted and block numerous roads. Near-total power loss is expected with outages that could last from several days to weeks.

Category 3

-

Winds 111 to 129 mph

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. Electricity and water will be unavailable for several days to weeks after the storm passes.

Category 4

-

Winds 130 to 156 mph

Catastrophic damage will occur:

Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls. Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months.

Category 5

-

Winds 157 mph or higher

Catastrophic damage will occur:

A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.
