* HEAT INDEX READINGS...105 to 109 degrees.

* IMPACTS...The combination of hot temperatures and high humidity
will likely 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 matter of minutes.
A Heat Advisory means that a period of hot temperatures is
expected. The combination of hot temperatures and high humidity
will combine to create a situation in which heat illnesses are
possible. Drink plenty of fluids, stay in an air-conditioned
room, stay out of the sun, and check up on relatives and
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.
