afternoon with heat indices near 105 degrees across Central Alabama
and up to 107 degrees over North Alabama due to temperatures in the

* IMPACTS…Heat-related illnesses may be possible for those
outdoors in unshaded areas.

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.

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 check up
on relatives and neighbors.
