Have an emergency first aid kit available, including a battery operated NOAA Weather Radio with tone alert capabilities. It’s one of the quickest and most reliable ways to receive severe weather information.

When a severe thunderstorm warning has been issued act quickly, but do not panic. If you’re at home, go to the basement or find an interior room on the lowest floor like a closet or bathroom. Remember, mobile homes are not considered safe indoor shelters. You should seek substantial shelter elsewhere.

In schools, hospitals, factories, and shopping centers, go to a predestinated shelter. If a shelter is not available, go to an interior small room or hallway on the lowest floor and get under a sturdy piece of furniture. Stay away from large open rooms with windows such as auditoriums and gymnasiums.

If you are caught outdoors and no shelter is available, find a ditch or low lying area and stay crouched low to the ground protecting your head. DO NOT lie flat on the ground. If you’re on a boat, head for safe harbor and find safe shelter immediately.

Stay informed and be alert if threatening weather is in your area. Remember that severe thunderstorms can develop quickly giving you little time to react to the danger. If a thunderstorm approaches, take the necessary precautions to protect yourself!
