...HEAT ADVISORY REMAINS IN EFFECT UNTIL 7 PM CDT THIS EVENING...

* EVENT...High pressure aloft across the area will allow for
  temperatures to climb into the middle to upper nineties. These

* TIMING...Heat indices will be near 105 to 109 in the afternoon
  and early evening before lowering.

* IMPACT...Precautions should be taken to prevent heat related
  illnesses, including limiting outdoor work activities to the
  morning before temperatures rise and early evening after the
  readings lower.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Take frequent rest breaks in shaded or air conditioned
environments. 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.

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
neighbors.
