...EXCESSIVE HEAT WARNING IN EFFECT FROM NOON SATURDAY TO MIDNIGHT EDT SATURDAY NIGHT...
The National Weather Service in Detroit/Pontiac has issued an
Excessive Heat Warning, which is in effect from noon Saturday to
midnight EDT Saturday night.
HAZARDOUS WEATHER...
* Temperatures are expected to reach highs in the mid 90s
Saturday afternoon. These readings, along with increasingly
humid air moving into the region, could lead to heat index
reaching 105 degrees Saturday afternoon into Saturday
evening.
IMPACTS...
* The hot and humid air could lead to potentially hazardous
conditions, particularly for the elderly and those with pre-
existing health conditions.
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.
