...RED FLAG WARNING REMAINS IN EFFECT UNTIL 9 PM PDT THURSDAY FOR
DRY THUNDERSTORMS AND GUSTY OUTFLOW WINDS FOR FIRE WEATHER ZONES
658, 659, AND 661...

* 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
  from this afternoon and evening and again Thursday into
  Thursday night. 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 Tuesday and thunderstorms expect
  for two more days, multiple days in a row of lightning strikes
  on our dry fuels could result in a critical number of new
  wildfires.

* THUNDERSTORMS...Multiple lightning strikes occurred in the
  higher terrain of the Cascades mountains yesterday afternoon
  and evening 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.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Red Flag Warning means that critical fire weather conditions
are either imminent or occurring now. Any fires that develop will
likely spread quickly. Outdoor burning is not recommended.
