A fisherman’s worst nightmare is being out on the water, finding that
perfect spot where the fish are practically jumping into
the boat, and along comes a storm. In Florida, thunderstorms
occur almost daily. In fact, the frequency of storms in
Florida, and their sometimes limited duration—think
the 45 minute 4:00 pm daily afternoon boomer—gives
some boaters a sense of invincibility when a storm comes
up. Not so. A boat on the water, or a fisherman on the beach
or a pier are some of the most dangerous places to be during
an electrical storm. Caution should always be used in the
face of a storm.
Many misconceptions exist about lightning. Most of the
average person’s general knowledge of lightning comes
from school yard rumors and old wive’s tales. We consulted
the National Weather Service to sort out the myth from the
facts.

Thunder & Lightning
Lightning is a sudden and visible discharge of electricity produced
in response to the build up of electrical potential between cloud
and ground, between clouds, within a single cloud, or between
a cloud and surrounding air. It is the visible electric discharge
between rain clouds or between a rain cloud and the earth. Thunder
is the result of rapid expansion of superheated air caused by
the extremely high temperature of lightning. As the lightening
bolt passes through the air, the air expands faster than the speed
of sound generating a sonic boom. Actually, millions of sonic
booms are created along the path of the lightning bolt, which
we hear as a rumble. Since light travels faster than sound, you
will generally see the lightning before you hear thunder. When
you see lightning at the same time you hear thunder…it’s
time to take cover!
Lightning Safety
Each year about 400 children and adults in the U.S. are struck
by lightning while working outside, boating and fishing, standing
on the beach and during other outdoor activities. About 80 people
are killed and several hundred more are left to cope with permanent
disabilities. Lightning travels between two objects, typically
between two clouds or between a cloud and the earth. When lightning
travels toward the earth, it finds the tallest object to strike;
that is why you should not seek shelter under a tree during a
storm.
Get off the water, out of open spaces, and away from
trees
The two mostly deadly places you can be are in open spaces or
under trees. Avoid open spaces and trees during thunderstorms.
Also avoid things that conduct electricity such as water, utility
lines, and metal fences. A boat on the open water and a fisherman
with a rod in hand are excellent targets for lightning. When you
are out on the water and a storm comes up--head for the safety
of shore immediately. If that is not possible, radio for help
and then disconnect the ariels and powerleads; in the event of
a lightning strike you could be left stranded. Put your fishing
rods down, do not touch any metal and crouch down as low as possible.
If you can, keep your head inside the cabin. When you feel the
electrical charge -- if your hair stands on end or your skin tingles
-- lightning may be about to strike you. Drop to the ground immediately.
If you're still outdoors and lightning has struck close to you,
crouch down into a ball on the balls of your feet. Your goal is
to be the smallest target possible with the least contact with
the ground. Do not seek shelter under tall or isolated trees or
unsubstantial shelters. It's better to be wet from the rain than
dead or disabled from lightning.
All thunderstorms produce lightning and are dangerous, but most
of the danger can easily be avoided. If you hear thunder, lightning
is close enough to strike. Lightning often strikes as far as 10
miles away from rainfall and many deaths occur ahead of the storm.
It is important that you seek shelter once you hear the thunder,
even if the storm looks far away. Dark cloud bases and increasing
wind indicate the formation of a storm. It is important to watch
for these signals even before you hear thunder to get out of the
way of approaching danger. During thunderstorms, no place outside
is safe. But lightning safety experts agree that you can minimize
your risk if thunderstorms develop or approach by following these
steps:
Use the 30/30 rule.
When you see lightning, count the seconds until you hear thunder.
If this time is 30 seconds or less, quickly go inside a substantial
building. If such a building is not available, a metal-topped
vehicle is the next best choice.
Wait at least 30 minutes after seeing the last lightning or hearing
the last thunder before going back outside.
Some Enlightening Facts & Safety Tips About Lightning
- Average Lightning Stroke is 6 miles long.
- The Temperature of lightning's return stroke can reach 50,000
degrees Fahrenheit.
- The surface of the sun is not even that hot! (around 11,000
degrees Fahrenheit).
- Average Thunderstorm is 6-10 miles wide.
- Average Thunderstorm travels at a rate of 25 miles per hour.
- Once the leading edge of a thunderstorm approaches to within
10 miles, you are at immediate risk due to the possibility of
lightning strokes coming from overhanging anvil cloud. Because
of this, many lightning deaths and injuries occur with clear
skies directly overhead.
- On average, thunder can only be heard over a distance of 3-4
miles, depending on humidity, terrain and other factors.
- Approximately 100,000 thunderstorms occur in the United States
each year.
- Approximately 10% of all thunderstorms are severe enough to
produce high winds, flash floods, and tornadoes.
- Thunderstorms cause an average of 200 deaths and 700 injuries
in the United States each year.
Storms can blow up quickly, and the best way to be prepared is
to listen to forecasts and warnings through NOAA Weather Radio
and review you local television and radio for forecasts and trends.
Knowing the dangers and being prepared can help prevent injury
or even death in the event of an electrical storm.
