It's important to know when you should stop outdoor activities due to lightning in the area. You should know that it doesn't have to be raining for you to be struck by lightning as lighting can strike up to 10 miles away from the parent thunderstorm.
30 / 30 Rule:
If after seeing lightning, you cannot count to 30 before hearing thunder, go indoors!
Stay indoors for 30 minutes after hearing the last clap of thunder.
A safe shelter from lightning is either a substantial building or a enclosed metal vehicle. A safe building is one that is fully enclosed with a roof, walls and floor, and has plumbing or wiring. Examples include a home, school, church, hotel, office building or shopping center.A safe vehicle is any fully enclosed metal-topped vehicle such as a hard-topped car, minivan, bus, truck, etc. While inside a safe vehicle, do not use electronic devices such as radio communications during a thunderstorm.
Once inside, stay away from showers, sinks, bath tubs, and electronic equipment such as stoves, radios, corded telephones and computers.
Unsafe buildings include car ports, open garages, covered patios, picnic shelters, beach pavilions, golf shelters, tents of any kinds, baseball dugouts, sheds and greenhouses. Unsafe vehicles include golf carts, convertibles, motorcycles, or any open cab vehicle.
