not taken. The very Young, the elderly, those without air
conditioning, and those participating in strenuous outdoor
activities will be the most susceptible. Also, car interiors
can reach lethal temperatures in a matter of minutes.

Precautionary/preparedness actions...

An excessive heat warning means that a prolonged period of
dangerously hot temperatures and high humidity will occur. In
addition, nighttime conditions will remain warm and muggy
providing little chance for relief. This combination will create
a dangerous situation in which heat-related illnesses are likely,
especially for those living in un-air conditioned homes or
apartments. People in the warning area are advised to avoid
poorly ventilated areas and prolonged work in the sun. Use air
conditioning in your house or apartment if it is working
correctly. If you do not have air conditioning, keep your house
or apartment well ventilated with fans, and try to spend some
time in an air conditioned environment to give your body a break
from the heat.

People in the Saint Louis metropolitan area can get information
about cooling centers or energy assistance related to the
excessive heat by calling the United way of greater Saint Louis
at 800-427-4626, or if calling from a land line phone dial 2-1-1.
You can also call cool down Saint Louis at 314-241-7668.
