Fire Weather Warning
Statement as of 3:41 PM PDT on July 5, 2009


... Red flag warning remains in effect until 11 am PDT Monday for a
combination of winds and low relative humidities this evening followed
by thunderstorms producing abundant lightning tonight...

A red flag warning remains in effect until 11 am PDT Monday.

A cold front will cross the Oregon Cascades this evening and
continue moving northeast across the lower Columbia Basin through
the overnight hours into Monday morning. Winds ahead of the front
will increase this evening to around 10 to 20 mph. The winds in
combination with relative humidities ranging from 8 to 15 percent
will result in critical fire weather conditions.

Scattered thunderstorms will develop tonight with periods of
enhanced lightning activity across the lower elevation
Grasslands. Rainfall amounts are expected to be relatively light.

Precautionary/preparedness actions...

A red flag warning means that critical fire weather conditions
are either occurring now... or will shortly. A combination of
strong winds and low relative humidity will create explosive fire
growth potential. For additional weather information... check our
