Some thunderstorms can be seen approaching, while others hit without warning. It is important to learn and recognize the danger signs and to plan ahead.

Check for hazards in the yard
Dead or rotting trees and branches can fall during a severe thunderstorm and cause injury and damage.
Make sure that all family members know how to respond after a thunderstorm
- Teach family members how and when to turn off gas, electricity and water
- Teach children how and when to call 911, police fire department and which radio station to tune for emergency information
Severe Thunderstorm Watches and Warnings
A severe thunderstorm watch is issued by the National Weather Service when the weather conditions are such that a severe thunderstorm (damaging winds 58 miles per hour or more, or hail three-fourths of an inch in diameter or greater) is likely to develop. This is the time to locate a safe place in the home and tell family members to watch the sky and listen to the radio or television for more information.
A severe thunderstorm warning is issued when a severe thunderstorm has been sighted or indicated by weather radar. At this point, the danger is very serious and everyone should go to a safe place, turn on a battery-operated radio or television, and wait for the “all clear” by the authorities.
Learn how to respond to a tornado.
Tornadoes are spawned by thunderstorms.. When a “severe thunderstorm warning” is issued, review what actions to take under a “tornado warning”.
When a storm seems to be developing.
Check weather forecasts on broadcast news, The Weather Channel on Cable TV, or access the Weather Links on the Internet.
Develop an emergency communication plan.
In case family members are separated from one another during a thunderstorm (a real possibility during the day when adults are at work and children are at school), have a plan for getting back together.
Ask an out-of-state relative or friend to serve as the “family contact”. After a disaster, it’s often easier to call long distance. Make sure everyone knows the name, address, and phone number of the contact person.
