...RED FLAG WARNING REMAINS IN EFFECT UNTIL 8 PM PDT THIS EVENING
FOR LIGHTNING AND GUSTY OUTFLOW WINDS FOR FIRE WEATHER ZONE 658...

* AFFECTED AREA...Fire Weather Zone 658 West Slopes of the North 
  Cascades Generally above 1500 Feet.

* LIGHTNING...Scattered thunderstorm coverage is possible across 
  the North Cascades.

* OUTFLOW WINDS...Any storms that develop will be capable of gusty
  and erratic outflow winds between 20 and 40 miles per hour. 
  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.

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.
