* WHAT...Heat index values up to 102. Overnight temperatures
remaining warm in the lower 70s.

* WHEN...Until 9 PM CDT Thursday.

* IMPACTS...Hot temperatures and high humidity may cause heat
illnesses. Prolonged heat waves lead to cumulative heat stress for
those who cannot adequately cool down and recover each night.
Cumulative heat stress significantly increases the risk of heat
exhaustion and heat stroke as time goes on.

Information: 
Drink plenty of fluids, stay in an air-conditioned room, stay out of
the sun, and check up on relatives and neighbors.

Do not leave young children and pets in unattended vehicles. Car
interiors will reach lethal temperatures in a matter of minutes.

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.
