...HEAT ADVISORY IN EFFECT FROM NOON TUESDAY TO 5 PM PDT THURSDAY...

* WHAT...Hot conditions with high temperatures ranging from the
  upper 80s to the mid 90s and low temperatures in the 60s and lower
  70s. This will pose a moderate to locally major risk of
  heat-related illness.

* WHERE...Foothills and Valleys of the North Cascades, Foothills and
  Valleys of Central King County, Foothills and Valleys of Pierce
  and Southern King Counties, Foothills and Valleys of Snohomish and
  Northern King Counties, and Foothills and Valleys of Thurston and

* WHEN...From noon Tuesday to 5 PM PDT Thursday.

* 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...The hottest temperatures will primarily be
  focused in the Cascade valleys, where temperatures in the mid 90s
  can be expected. The overnight lows will remain very warm and
  provide little to no relief, especially in locations such as
  Packwood, Marblemount, and Darrington.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
