dry thunderstorms for Oregon fire weather zones 602... 603... 604...
605... 606... 607... and 608... as well as Washington fire weather

* affected area... Oregon fire weather zones 602... 603... 604...
605... 606... 607... 608 and Washington zones 604 and 660. This
includes the Clark County lowlands in southwest Washington and
the extreme South Washington Cascades and foothills... and much
of northwest Oregon from the Coast Range to the Cascades.

* Timing... critical fire weather conditions will continue through
midnight.

* Stability... mid-level Haines 6 conditions through midnight.

* Relative humidity... improving recovery tonight... but generally
just 40 to 60 percent on slopes and ridges.

* Thunderstorms... a threat of thunderstorms over the south half of
the forecast area this evening then spreading north thereafter.
Very little rainfall with any storm... especially those over the
north half of the region.

* Impacts... the combination of an increasingly unstable
environment... critically dry fuels and possible lightning may
result in rapid fire spread of on-going incidents and the
potential for new starts.

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... low relative
humidity... and warm temperatures will create explosive fire
growth potential.
