...HEAT ADVISORY REMAINS IN EFFECT FROM 10 AM SUNDAY TO 10 PM PDT
MONDAY...

* WHAT...Hot conditions with high temperatures up to 85 to 90
  degrees and up to 95 degrees in the Cascade Valleys, and low
  temperatures down to 55 to 65 degrees. This will pose a moderate
  risk of heat-related illness.

* WHERE...Portions of northwest and west central Washington.

* WHEN...From 10 AM Sunday to 10 PM PDT Monday.

* IMPACTS...Heat will significantly increase the risk of
  heat-related illnesses for those who are sensitive to heat,
  especially those without effective cooling or adequate hydration.

* ADDITIONAL DETAILS...Water temperatures, including area lakes and
  rivers, remain cold (in the upper 40s and 50s) which significantly
  increases the risk of cold shock and drowning, even for confident
  swimmers in calm water. Cold water drains body heat up to 25 times
  faster than cold air.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If planning to head to the water, always wear a life jacket and
dress for water temperature, not air temperature. Keep a close eye
on children and pets near water. Know the signs of cold shock, such
as involuntary gasping and rapid breathing, which drastically
increases the risk of drowning.

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.

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 lightweight and loose fitting clothing when possible.
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.
