Be Safe in Dangerous Weather!
No matter where you live, the weather can
become dangerous. From tornadoes and hurricanes
to floods and too much heat or cold, it's
a good idea to know about the potentially
dangerous weather in your area and have a
family weather emergency plan. The American
Red Cross suggests taking these precautions:
-
Decide where to go and where you would be
safe if a flood, severe thunderstorm, or
tornado warning is issued - whether you're
at home, at school, outdoors, or in a car.
-
Have a family disaster supply kit, and know
where it is. The kit should include such
items as a flashlight, batteries, a batter-operated
radio, and a first aid kit. (For a complete
list of supplies that the American Red Cross
recommends, visit: http://www.weather.com/safeside/red_cross/safe_kit.html on the Internet or contact your local Red
Cross chapter.)
-
Make plans for communication in case your
family members become separated. Have a friend
or relative who lives outside your area be
the contact person.
-
Agree upon a place where family members can
meet if separated.
-
Have a plan in place also for family pets.
Contact your local Red Cross chapter for
information on pet care during an emergency.
Types of Clouds
Clouds are made of particles of water or
ice suspended in the air. When these particles
come together, they form a cloud. Larger
water droplets may get too big and heavy
for the clouds to hold, so they fall to the
earth as rain, sleet, or snow. There are
four major types of clouds:
-
Cirrus Clouds:
Are the highest clouds about 50,000 to 55,000
feet above the Earth. They form feathery
wisps and are made of ice crystals.
-
Cummulonimbus Clouds:
Are middle-level clouds at 6,500 to 24,000
feet. They are flat and dark on the bottom
and billow upward. They can cause the heaviest
downpours, often with thunder and lightning.
-
Cumulus Clouds:
Are white and puffy and are about 5,000 feet
above the Earth. They sometimes look like
huge balls of cotton.
-
Stratus Clouds:
Are made of low layers of gray clouds that
usually cover the whole sky. They are fog-like
and appear in flat layers.
Resources
Besides books at your local library about
weather, the Internet has many weather-related
sites. You can learn about the weather all
over the world and see radar sweeps that
show current weather in any part of the country.
Use a search engine to explore.
Also, the National Weather Service may have
a local office in your area and can be an
excellent resource.
