Severe Thunderstorm Watch
A severe thunderstorm watch means severe thunderstorms are possible. Be alert for changes in the weather, monitor local radio or television and be prepared to act quickly.
Severe Thunderstorm Warning
A severe thunderstorm warning means severe thunderstorms are occurring, which may produce hail and/or very strong winds. Some of these winds are called straight-line winds, and can reach speeds of 100 miles per hour. Severe thunderstorms can also produce tornadoes with little or no warning.
Tornado Watch
A tornado watch means conditions are favorable for the development of severe thunderstorms with tornadoes. When a tornado watch is issued, be alert for changes in the weather, monitor local radio or television and be prepared to act quickly.
Tornado Warning
A tornado warning means a tornado has been sighted or indicated by radar. If a tornado warning is issued for your area, seek shelter immediately:
At home
Go to the basement of your home and take shelter under the stairs or sturdy furniture such as a workbench or table. If you don’t have a basement, seek shelter in a small room at the lowest level, and/or near the center of your home, such as a closet or bathroom. Avoid areas with windows.
At work or school
Immediately find the building’s designated shelter area. Stay away from large, open rooms, auditoriums, gymnasiums and any room with windows. Lie low and cover your head and neck with your hands and arms.
At a shopping mall
Locate the designated shelter area or go to the center of the building on the lowest level. Stay away from large, long span roofs, open rooms and windows. Do not go to your car - you are generally safer in a building than in the open.
In a car or mobile home
Leave your vehicle or mobile home immediately and move to the nearest safe structure or storm shelter. If you are caught in the open, lie flat in a nearby ditch or depression with your hands and arms covering the back of your head and neck.
