Thunderstorms accompanied by lightning are frequent occurrences in Missouri during the spring and summer months. Thunderstorms may occur singly, in clusters, or in lines. Some of the most severe thunderstorms occur when a single thunderstorm affects one location for an extended time. Thunderstorms typically produce heavy rain for 30 minutes to an hour. Warm, humid conditions are highly favorable for thunderstorm development. About 10 percent of thunderstorms are classified as severe—one that produces hail at least three-quarters of an inch in diameter, has winds of 58 miles per hour or higher, or produces a tornado.

Lightning often strikes outside of heavy rain and may occur as far as 10 miles away from any rainfall. "Heat lightning" is actually lightning from a thunderstorm too far away for thunder to be heard. However, the storm may be moving in your direction. Most lightning deaths and injuries occur when people are caught outdoors in the summer months during the afternoon and evening. Your chances of being struck by lightning are estimated to be 1 in 600,000, but can be reduced even further by following safety precautions. Lightning strike victims carry no electrical charge and should be attended to immediately.

Familiarize yourself with these terms to help identify a thunderstorm hazard:

  • Severe Thunderstorm Watches are issued to tell you when and where severe thunderstorms are likely to occur.
  • Severe Thunderstorm Warnings are issued when severe weather has been reported by spotters or indicated by radar. Warnings indicate imminent danger to life and property to those in the path of the storm.

Preparedness tips before a thunderstorm

Create a plan for you and your family in the event of a thunderstorm—at home, at work and at relatives’ or friends’ homes that you visit frequently. Always be alert to changing weather conditions.

Remember, the following are guidelines if a thunderstorm is likely in your area:

  • Listen to radio, television, or NOAA Weather Radio for weather reports and emergency information.
  • Postpone outdoor activities.
  • Remember "If thunder roars, go indoors" because no place outside is safe when lightning is in the area. Everyone should stay indoors until 30 minutes after they hear the last clap of thunder.
  • Get inside a home, building, or hard top automobile (not a convertible). Although you may be injured if lightning strikes your car, you are much safer inside a vehicle than outside.
  • Unplug appliances and other electrical items such as computers and turn off air conditioners. Power surges from lightning can cause serious damage.
  • Secure outdoor objects that could blow away or cause damage.
  • Shutter windows and secure outside doors. If shutters are not available, close window blinds, shades, or curtains.
  • Long-term preparations: Remove dead or rotting trees and branches that could fall and cause injury or damage during a severe thunderstorm.

What to do during a thunderstorm

After getting inside a home or building:

  • Avoid showering or bathing and any contact with plumbing. Plumbing and bathroom fixtures can conduct electricity. Do not wash your hands, wash dishes or do laundry.
  • Cordless and cellular telephones are safe to use. Use a corded telephone only for emergencies.
  • Avoid contact with electrical equipment or cords.
  • Stay away from windows and doors, and stay off porches.
  • Because concrete conducts electricity, do not lie on concrete floors and do not lean against concrete walls.
  • Everyone should stay indoors until 30 minutes after they hear the last clap of thunder.

If you find yourself outside when a thunderstorm hits, avoid the following:

  • Remember, rubber-soled shoes and rubber tires provide NO protection from lightning. However, the steel frame of a hard-topped vehicle provides increased protection if you are not touching metal.
  • Natural lightning rods such as a tall, isolated tree in an open area.
  • Hilltops, open fields, the beach, or a boat on the water.
  • Isolated sheds or other small structures in open areas.
  • Anything metal—tractors, farm equipment, motorcycles, golf carts, golf clubs, and bicycles.

If you are in certain situations, do the following:

  • In a forest, seek shelter in a low area under a thick growth of small trees.
  • In an open area, go to a low place such as a ravine or valley. Be alert for flash floods.
  • On open water, get to land and find shelter immediately.
  • Anywhere you feel your hair stand on end (which indicates that lightning is about to strike), squat low to the ground on the balls of your feet. Place your hands over your ears and your head between your knees.

What to do if you have unmet needs following a thunderstorm

Throughout the recovery period, it is important to monitor local radio or television reports and other media sources for information about where to get emergency housing, food, first aid, clothing, and financial assistance. The following section provides general information about the kinds of assistance that may be available.

Direct Assistance

Direct assistance to individuals and families may come from any number of organizations

Other volunteer and faith-based organizations

These organizations provide food, shelter, supplies and assist in clean-up efforts.
