Thunderstorm Safety Tips

TERMS TO KNOW

Severe Thunderstorm Watch  is issued when severe thunderstorms are possible in and close to the watch area. The watch area is issued to alert you to the possibility that thunderstorms with damaging winds and large hail may develop. Listen to NOAA Weather Radio and your local media weather updates and stay informed.

Severe Thunderstorm Warning is issued when a severe thunderstorm is going to move through Nassau County soon. The key is to remain CLAM, but take precautionary action IMMEDIATELY to protect your life and property.

BE PREPARED

Severe weather warning are issued on a county basis. Have disaster supplies on hand, including:

  • Flashlight and extra batteries
  • Battery-operated radio and extra batteries
  • First aid kit and manual
  • Emergency food and water
  • Non-electric can opener
  • Essential medicines
  • Checkbook, cash, credit cards, ATM cards

BEFORE THE STORM

1. Check the weather forecast before leaving for extended periods outdoors.

2. Watch for signs of approaching storms.

3. If a storm is approaching, keep a NOAA Weather Radio or AM/FM radio with you.

4. Postpone outdoor activities if storms are imminent.

5. Check on neighbors who require special assistance: infants, the elderly, and people with disabilities.

DURING THE STORM

Remember: If you can hear thunder, you are close enough to the storm to be struck by lightning. Go to safe shelter immediately.

1. Move to a sturdy building or car. DO NOT take shelter in small sheds, under isolated trees, or in convertible automobiles.

2. If lightning occurs and sturdy shelter is not available, get inside a hard top automobile and keep the winddows up.

3. Get out of boats and away from water.

4. Telephone lines and metal pipes can conduct electricity. Unplug appliances not necessary for obtaining weather information. Use phones only in an emergency.

5. Do not take a bath or shower.

6. Turn off air conditioners. Power can overload the compressors.

7. Get to higher ground if flash flooding or flooding is possible. DO NOT attempt to drive to safety. Most flash flooding deaths occur in automobiles.

If you are caught outdoors and no shelter is nearby:

1. Find a low spot away from trees, fences, and poles. Make sure the place you pick is not subject to flooding.

2. If you are in the woods, take shelter under the shorter trees.

3. If you feel your skin tingle or your hair stand on end, squat low to the ground and the balls of your feet. Place your hands on your knees with your head between them. Make yourself the smallest target possible; minimize your contact with the ground.

AFTER THE STORM

1. Check on neighbors who may require special assistance - infants, the elderly, and people with disabilities.

2. Avoid all downed power lines. Assume that all have live electricity.

3. Continue to monitor NOAA Weather Radio and local media for latest weather updates.
