...DRY THUNDERSTORMS EXPECTED FOR CENTRAL OREGON TUESDAY, FOLLOWED
BY DRY AND WINDY CONDITIONS ACROSS THE KITTITAS VALLEY AND
WASHINGTON BASIN WEDNESDAY...

.The high pressure currently leading to hot and dry conditions
will start to break down Tuesday into Wednesday, allowing for dry
thunderstorms to develop across central Oregon. Once high pressure
has completely broken down on Wednesday, winds will pick up. With
RHs having little time to recover from Monday and Tuesday's heat,
this will lead to potentially critical fire weather conditions
across the Kittitas Valley and into the Washington Columbia Basin.

The National Weather Service in Pendleton has issued a Red Flag
Warning for abundant lightning, which is in effect from 2 PM to
9 PM PDT Tuesday.

* AFFECTED AREA...Fire Weather Zone 700 Central Mountains of
Oregon.

* TIMING...From 2 PM to 9 PM PDT Tuesday.

* IMPACTS...Any fire that develops will catch and spread
quickly. Outdoor burning is not recommended.

* RAINFALL AMOUNTS...Storms are mostly expected to be dry, with
rainfall amounts less than a tenth of an inch. A few isolated
storm cells could produce rainfall amounts of 0.1 to 0.2
inches.

* OUTFLOW WINDS...As high as 45 mph.

A Red Flag Warning means that critical fire weather conditions
are either occurring now, or will shortly. A combination of
strong winds, low relative humidity, and warm temperatures can
contribute to extreme fire behavior.

* WHAT...Hot conditions with temperatures up to 100 degrees. This
will pose a moderate to major risk of heat-related illness.

* WHERE...Eastern Columbia River Gorge of Oregon and Washington.

* WHEN...Until 9 PM PDT Tuesday.

* IMPACTS...Hot temperatures may cause heat illnesses. 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.

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.
