What to Do When Thunderstorm Comes
-
Severe thunderstorms are officially defined as storms that are capable of producing hail that is an inch or larger or wind gusts over 58 mph. Hail this size can damage property such as plants, roofs and vehicles. Wind this strong is able to break off large branches, knock over trees or cause structural damage to trees. Some severe thunderstorms can produce hail larger than softballs or winds over 100 mph, so please pay attention to the weather so you know when severe storms are possible. Thunderstorms also produce tornadoes and dangerous lightning; heavy rain can cause flash flooding. These hazards will be covered in more detail under next articles about tornado, lightning safety and flood safety.

Before
Be Weather-Ready: Check the forecast regularly to see if you're at risk for severe weather.
Sign Up for Notifications: Know how your community sends warning. Some communities have outdoor sirens. Others depend on media and smart phones to alert residents to severe storms.
Create a Communications Plan: Have a family plan that includes an emergency meeting place and related information. Pick a safe room in your home such as a basement, storm cellar or an interior room on the lowest floor with no windows.
Practice Your Plan: Conduct a family severe thunderstorm drill regularly so everyone knows what to do if a damaging wind or large hail is approaching. Make sure all members of your family know to go there when severe thunderstorm warnings are issued. Don't forget pets if time allows.
Prepare Your Home : Keep trees and branches trimmed near your house. If you have time before severe weather hits, secure loose objects, close windows and doors, and move any valuable objects inside or under a sturdy structure.
Help Your Neighbor: Encourage your loved ones to prepare for severe thunderstorms. Take CPR training so you can help if someone is hurt during severe weather.

At Your Workplace or School: Stay away from windows if you are in a severe thunderstorm warning and damaging wind or large hail is approaching. Do not go to large open rooms such as cafeterias, gymnasiums or auditoriums.
