...HEAT ADVISORY REMAINS IN EFFECT FROM 11 AM THIS MORNING TO
8 PM PDT WEDNESDAY...

* TEMPERATURES...Afternoon high temperatures of 92 to 102 degrees
  are expected today and Wednesday, with warmest temperatures
  between 3 and 7 PM. Temperatures will be very slow to cool, with
  overnight low temperatures only reaching the lower 60s for a few
  hours early Wednesday morning.

* TIMING...Hot temperatures develop this afternoon and will be
  very slow to cool tonight, limiting relief before hot
  conditions return on Wednesday.

* IMPACTS...Hot temperatures and limited relief overnight will
  increase the chance for heat related illnesses, especially for
  those who are sensitive to heat. People most vulnerable
  include those who spend a lot of time outdoors, those without
  air conditioning, those without adequate hydration, young
  children, and the elderly.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Heat Advisory means that a period of hot temperatures is
expected. Hot temperatures will create a situation in which heat
related illnesses are possible. Drink plenty of water, stay in an
air-conditioned room, stay out of the sunshine, and check up on
relatives and neighbors.

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.
