EVENING...

* TEMPERATURES...Highs in the low to mid 90s.

* HEAT INDICES...Peak heat indices of 100 to 105.

* IMPACTS...The extended duration of heat, combined with nearly
full sunshine, and oppressive warmth at night will lead to
hazardous conditions, particularly for the elderly and those
with pre-existing health conditions. Residents of the city of
Chicago can call 3...1...1...to request well being checks for
elderly friends or family members, or for information on
finding the nearest cooling center.

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.
