...EXCESSIVE HEAT WARNING IN EFFECT FROM NOON TUESDAY TO 8 PM CDT
SATURDAY...

The National Weather Service in Saint Louis has issued an
Excessive Heat Warning, which is in effect from noon Tuesday to
8 PM CDT Saturday. The Excessive Heat Watch is no longer in
effect.

* TIMING...Tuesday afternoon through Saturday evening.

* HEAT INDEX VALUES...Between 105 and 113 each afternoon and
  early evening.

* IMPACTS...The combination of hot temperatures and high
  humidity will lead to an increased risk of heat-related stress
  and illness. 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.

To reduce risk during outdoor work, the Occupational Safety and
Health Administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency, call 9-1-1 immediately.

Where`s baby? Look before you lock! Young children and pets
should never be left unattended in vehicles under any
circumstances. This is especially true during warm or hot weather
when car interiors can reach lethal temperatures in a matter of
minutes.

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.
