...EXCESSIVE HEAT WARNING IN EFFECT FROM NOON CDT THURSDAY TO 7

PM CDT SATURDAY...

The National Weather Service in Chicago has issued an Excessive
Heat Warning, which is in effect from noon CDT Thursday to 7 PM
CDT Saturday. The Excessive Heat Watch is no longer in effect.

* HIGH TEMPERATURES...Peaking well into the 90s each day, with
Friday and Saturday potentially in the upper 90s to near 100
degrees.

* MAXIMUM HEAT INDICES...Peaking 104 to 114 each afternoon.

* LOW TEMPERATURES...Lows only in the upper 70s to near 80 on
Thursday and Friday nights will offer little to no relief from
the heat.

* IMPACTS...The cumulative effects of temperatures and heat
index values this high could lead to heat related illnesses
with prolonged exposure. Those without air conditioning,
elderly, small children, and pets are especially susceptible.
Plan ahead. Have a cool place to shelter from the heat. Avoid
outdoor activity, especially strenuous ones, during the peak
heating times of the day.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Take extra precautions...if you work or spend time outside. When
possible...reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

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.

An Excessive Heat Warning means that a prolonged period of
dangerously hot temperatures will occur. The combination of hot
temperatures and high humidity will combine to create a dangerous
situation in which heat illnesses are likely. Drink plenty of
fluids...stay in an air-conditioned room...stay out of the sun...
and check up on relatives and neighbors.

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.
