Thunderstorms
Thunderstorms are very common and affect great numbers of
people each year. Despite their small size in comparison to hurricanes and
winter storms, all thunderstorms are dangerous. Every thunderstorm produces
lightning. Other associated dangers of thunderstorms include tornadoes,
strong winds, hail, and flash flooding. Flash flooding is responsible for
more fatalities - more
than 140 annually - than any other thunderstorm-associated hazard.
Some
thunderstorms do not produce rain that reaches the ground. These are generically
referred to as dry thunderstorms and are most prevalent in the western
United States. Known to spawn wildfires, these storms occur when there
is a large layer of dry air between the base of the cloud and the ground.
The falling raindrops evaporate, but lightning can still reach the ground. Back
