* AFFECTED AREA...Fire Weather Zone 658 West Slopes of the North
Cascades Generally above 1500 Feet, Fire Weather Zone 659 West
Slopes of the Central Cascades Generally above 1500 Feet and
Fire Weather Zone 661 East Portion of the Olympic Mountains.
* THUNDERSTORMS...Thunderstorms are favored along the eastern
slopes of the Olympic mountains and more so in the Cascades
this afternoon and evening. Some brief heavy rain or isolated
wetting rains are possible, but lightning strikes on very dry
fuel are capable of new fire starts.
* OUTFLOW WINDS...Outflow winds of 25 to 30 mph are possible.
Outflow winds can occur ahead of and behind storms and cause
erratic wind directions.
* IMPACTS...Scattered lightning in dry fuels can cause multiple
fire starts. Thunderstorms can also bring sudden sharp wind
shifts on existing fires, causing rapid changes in a fire's rate
of spread and direction of spread. Thunderstorm outflow winds
can be a threat for several hours following the start of a new
lightning-caused fire. If a fire were to begin, air quality may
diminish in the surrounding area. With lightning occurrences
having started earlier this week and thunderstorms expected
again today, multiple days in a row of lightning strikes on our
dry fuels could result in a critical number of new wildfires.
* THUNDERSTORMS...A few lightning strikes occurred in the higher
terrain of the Cascades mountains yesterday and that will
resume this afternoon and evening. Multiple days in a row of
lightning strikes on our dry fuels could result in a critical
number of new wildfires.

rainfall from thunderstorms is possible.

- Those within canyons or near burn scars should monitor for
updated information from local authorities.

quality may diminish in the surrounding area. With lightning
occurrences having started Tuesday and thunderstorms expect
for two more days, multiple days in a row of lightning strikes
