 * High temperatures are expected to reach into the mid 90s
   tomorrow, and into the mid to upper 90s on Saturday. Increasing
   humidity will yield heat indices peaking during the afternoon
   hours in the 100 to 110 degree range.

 * Low temperatures will only fall into the mid to upper 70s each
   night limiting the possible relief from the heat.


 * The hot and humid air will lead to potentially hazardous
   conditions, particularly for the elderly and those with pre-
   existing health conditions.


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 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.
