Though each one may cover only a few square miles, thunderstorms are often dangerous. They can produce lightning, hail tornadoes, and floods. Thunderstorms are set off by updrafts of warm air carrying water vapor. As the rising air cools, the vapor condenses and falls as rain.
Storm clouds can build up electrical charges as water and ice droplets tumble about inside.
During lightning storms, stay inside, away from windows, and don't use the telephone. Twisters' are powerful rotating winds. Most often they grow out of thunderstorms. When warm, moist air collides with cool, dry air, a huge updraft can result, creating a tornado. The funnel-shaped trunk that drops down from a thundercloud may whirl at a deadly 300 mph, destroying everything in its path.
