Thunderstorms and Lightning
Information...
In
the United States, there are an estimated 25 million
cloud-to-ground lightning flashes each year. While lightning
can be fascinating to watch, it is also extremely dangerous.
During the past 30 years, lightning killed an average of 73
people per year in the United States based on documented
cases. This is more than the average of 68 deaths per year
caused by tornadoes and the average of 16 deaths per year
caused by hurricanes. However, because lightning usually
claims only one or two victims at a time, and because
lightning does not cause the mass destruction left in the
wake of tornadoes or hurricanes, lightning generally
receives much less attention than the more destructive
weather-related killers. While documented lightning injuries
in the United States average about 300 per year,
undocumented injuries caused by lightning are likely much
higher.
Lightning Safety Awareness: An
Educational Problem
Few people really understand the dangers of lightning. Many people
don't act to protect their lives, property and the lives of others
promptly because they don't understand all the dangers associated with
thunderstorms and lightning. The first step in solving this problem is
to educate people so that they become aware of the behavior that puts
them at risk of being struck by lightning, and to let them know what
they can do to reduce that risk. Coaches and other adults who make
decisions affecting the safety of children must understand the dangers
of lightning.
Beware of a Developing
Thunderstorm
Thunderstorms are most likely to develop on warm summer days and go
through various stages of growth, development and dissipation. On a
sunny day, as the sun heats the air, pockets of warmer air start to
rise in the atmosphere. When this air reaches a certain level in the
atmosphere, cumulus clouds start to form. Continued heating can cause
these clouds to grow vertically upward in the atmosphere into
"towering cumulus" clouds. These towering cumulus may be one of the
first indications of a developing thunderstorm.
