HURRICANE CATEGORIES

Butler Builders Inc is posting the following information directly from NOAA’s  National Hurricane Center of the National Weather Service website in order to better inform the public of potential danger from high winds in hurricanes, or lesser storms.

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. Category 1 and 2 storms are still dangerous, however, and require preventative measures

History teaches that a lack of hurricane awareness and preparation are common threads among all major hurricane disasters. By knowing your vulnerability and what actions you should take, you can reduce the effects of a hurricane disaster.

After a storm is on the way may be too late, but preventive action ahead of time may save not only money in the long run, but the heartbreak of losing irreplaceable personal belongings, even if your family gets to safer ground and is not in danger.

Call now for an inspection and, if needed, remedial work on your home so that it will be best able to withstand storms and avoid losses.

A description of wind damage for the power of a storm is given below:

Types of Damage Due to Hurricane Winds
1

Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding 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.

83-95 kt
154-177 km/h
Extremely dangerous winds will cause extensive damage: Well-constructed frame homes could sustain major roof and siding damage.
