Thunderstorms
Each year, Alabama experiences a wide variety
of hazardous weather - from severe spring storms to the crippling effects
of a blanket of snow. In each case, the impact of weather can be serious.
In the Birmingham area, thunderstorms occur on the average of 75 days
of the year. While most of the more violent storms occur in the spring
and summer months, thunderstorms may develop at any time of the year.
Typically, thunderstorms may include very high winds, rain, hail and
lightning. The most dangerous aspect of a thunderstorm is lighting.
Lightning
Lightning kills two or three Alabamians each
year and several others are injured by lighting strikes. From 1990 to
1992, lightning killed four people and injured 127 in the state. Lightning
has been appropriately called "the underrated killer." Every
thunderstorm contains this potential killer. Whether it is the large,
springtime severe thunderstorm or the more common afternoon summer variety,
that electrical charge (which may reach 100 million volts) is always
present and searching for the path of the least resistance to complete
the circuit. It might strike you, an isolated tree or an object in the
open. Keep in mind that you do not have to be standing directly beneath
a cloud to be zapped.
If you are outdoors and cannot seek shelter in a large
building or house:
- Stay away from open water, tractors, farm
or lawn equipment or small metal vehicles such as motorcycles, bicycles
or golf carts.
- Do not stand underneath tall isolated trees
or telephone poles.
- Avoid hilltops or open areas.
- Stay away from wire fences, clotheslines,
metal pipes and railings.
Tornadoes
Alabama ranks fourth in the nation for the number
of killer tornados and fifth in the number of fatalities. In an average
year, National Weather Service records indicate that Alabama will experience
21 tornados that will be responsible for killing eight people.
The peak season for tornados in Alabama occurs
during March, April and May. Tornados sometimes occur in November. While
tornados can occur at any time, the most common is late afternoon and
early evening between 2 and 10 p.m.
Watches
A Tornado Watch is announced when the National
Weather Service has determined that conditions are favorable for the
formation of a tornado. You should be aware of the current weather conditions
in your area by staying tuned to the radio or television. A battery
operated weather radio is recommended. Be prepared to move to a safe
location immediately.
Tornadoes can come from any direction, but generally
approach the Birmingham area from the south or southwest. Report funnel-shaped,
rotating clouds immediately to the UAB Police Department. If you suspect,
but cannot confirm a sighting, report your suspicions.
Warnings
A Tornado Warning means that at least one tornado
has been sighted. You should take shelter immeadiately to protect yourself
from high winds, falling or flying objects and glass from breaking windows.
When a tornado threatens, the prime rule is
to get as low as you can to put as many walls between yourself and the
tornado as possible. The following are a few other tips:
- In any structure, go the lowest floor possible
to an interior room, interior hall, or a small room such as a closet
or bathroom. Most UAB buildings offer excellent protection, however,
upper floors and areas with exterior windows should be avoided.
- Don't try to watch the storm from a window,
sudden high winds can blow the window out.
- Avoid rooms with large, free-span roofs,
such as auditoriums or gymnasiums.
- In mobile homes or vehicles: if you don't
have time to reach a shelter, take cover and lie flat in a ditch,
culvert, excavation or ravine. Never attempt to outrun a tornado in
a car. You could easily drive into the path of the tornado.
Planning
Preparedness planning is an individual's responsibility.
Betting that the storm will not strike you may be the most costly mistake
you ever make. To protect yourself and your family, you should have
a safety plan in action now, before danger hits. The National Weather
Service advises that a severe preparedness plan should include:
- A thorough knowledge of the hazard and the
proper safety rules to be followed.
- Selection and designation of the best shelter
you have.
- A reliable method of recieving warning information.
- Instructions in the proper procedures to
follow when a watch or warning is issued - or if threatening weather
should develop with no advance warning - for each person in the household,
factory or business.Drills to test and practice the plan.<
For families, everyone should be involved in
developing the weather plans. Also, a safety plan should be developed
for each type of bad weather that affects your area.
Simply discussing what to do is not enough.
To be fully prepared and ready to act, the plan you develop at home
or at work should be rehearsed. Don't make a plan and then lock it away
for safekeeping. Practice it - often.
