Each year, about 400 children and adults in the U.S. are
struck by lightning while working outside, at sports events, on the beach,
mountain climbing, mowing the lawn or during other outdoor activities. About 67 people are killed and several
hundred more are left to cope with permanent disabilities. Many of these
tragedies can be avoided. Finishing the game, getting a tan, or completing a
work shift isn’t worth death or crippling injury.
Outdoors is the most
dangerous place to be during a lightning storm. When lightning is seen or
thunder is heard, or when dark clouds are observed, quickly move indoors or
into a hard-topped vehicle and remain there until well after the lightning
storm ends. Listen to forecasts and warnings through NOAA Weather Radio or your
local TV and radio stations. If lightning is forecast, plan an alternate
activity or know where you can take cover quickly.
The U.S. lightning season is
summer but lightning can strike year round! The Fourth of July is historically
one of the most deadly times of the year for lightning. In summer, more people
are outside, on the beach, golf course, mountains or ball fields. Outdoor jobs
such as construction and agriculture, and outdoor chores such as lawn mowing or
house painting are at their peak, putting those involved in danger.
1.
Postpone
activities promptly. Don't wait for rain. Many people take shelter from the rain, but most
people struck by lightning are not in the rain! Go quickly inside a completely
enclosed building, not a carport, open garage or covered patio. If no enclosed
building is convenient, get inside a hard-topped all-metal vehicle. A cave is a
good option outside but move as far as possible from the cave entrance.
2.
Be
the lowest point. Lightning hits the tallest object. In the mountains if you are above
tree line, you ARE the highest object around. Quickly get below tree line and
get into a grove of small trees. Don't be the second tallest object during a lightning
storm! Crouch down if you are in an exposed area.
3.
Keep
an eye on the sky.
Look for darkening skies, flashes of lightning, or increasing wind, which may
be signs of an approaching thunderstorm.
4.
Listen
for the sound of thunder. If you can hear thunder, go to a safe shelter immediately.
5.
If
you see or hear a thunderstorm coming or your hair stands on end, immediately
suspend your game or practice and instruct everyone to go inside a sturdy
building or car. Sturdy
buildings are the safest place to be. Avoid sheds, picnic shelters, baseball
dugouts, and bleachers. If no sturdy building is nearby, a hard-top vehicle
with windows closed will offer some protection. The steel frame of the vehicle
provides some protection if you are not touching metal.
6.
Listen
to NOAA Weather Radio.
Coaches and other leaders should listen for a tone-alert feature during
practice sessions and games.
7.
If
you can't get to a shelter, stay away from trees. If there is no shelter, crouch in the
open, keeping twice as far away from a tree as it is tall.
8.
Avoid
leaning against vehicles. Get off bicycles and motorcycles.
9.
Get
out of the water. It's a great conductor of electricity. Stay off the beach and out of small
boats or canoes. If caught in a boat, crouch down in the center of the boat
away from metal hardware. Swimming, wading, snorkeling and scuba diving are NOT
safe. Lightning can strike the water and travel some distance beneath and away
from its point of contact. Don’t stand in puddles of water, even if wearing
rubber boots.
10.
Avoid
metal! Drop metal
backpacks, stay away from clothes lines, fences, exposed sheds and electrically
conductive elevated objects. Don't hold on to metal items such golf clubs,
fishing rods, tennis rackets or tools. Large metal objects can conduct lightning.
Small metal objects can cause burns.
11.
Move
away from a group of people. Stay several yards away from other people. Don't share a
bleacher bench or huddle in a group.
Before going boating,
fishing, diving or enjoying other water sports or going out for business, check
the forecast. If severe weather is predicted, stay home. If you must go out,
take a radio and monitor forecasts. Return to shore as soon as possible if a
storm is predicted. If you caught out in a storm, here's what do to:

What to do if someone is struck by lightning:
Listen to NOAA Weather Radio
or local media for the latest severe thunderstorm WATCHES and WARNINGS.
Severe thunderstorms are those storms with winds in excess of 58 mph or
hail larger than 3/4 inches in diameter. When conditions are favorable for
severe weather to develop, a severe thunderstorm WATCH is issued.
Weather Service personnel use information from weather radar, satellite, lightning detection, spotters, and other sources to issue severe thunderstorm WARNINGS for areas where severe weather is imminent. Remember, however, that ALL thunderstorms produce deadly lightning.
Lighting Safety Awareness Week: June 19-25, 2005
NOOA Lightning Safety Team made up of government and private sector
businesses, has won the 2003 Annual Lightning Safety Recognition Award from the
National Lightning Safety Institute in Louisville, CO.
Summer is the peak season for one of the nation's deadliest
weather phenomena— lightning. Safeguarding U.S. residents from dangerous
lightning is the goal of this Website. The campaign is designed to lower lightning
death and injury rates and America's vulnerability to one of nature's deadliest
hazards.
In the United States, averages of 67 people are killed each year by
lightning. In 2003 there were 44 deaths. That's more than the annual number of
people killed by tornadoes or hurricanes. Many more are struck but survive.
However, they often report a variety of long-term, debilitating symptoms,
including memory loss, attention deficits, sleep disorders, numbness, dizziness,
and stiffness in joints, irritability, fatigue, weakness, muscle spasms,
depression, and an inability to sit for long.
Lightning is a serious danger. Through this site we hope
you'll learn more about lightning risks and how to protect yourself, loved ones
and your belongings.
In Wisconsin, lightning struck a man holding a tent metal pole, resulting in serious injuries. The bolt injured 7 nearby people who were standing in ankle deep water. Six of the eight people were hospitalized.
