The National Weather Service in Seattle has issued a Red Flag

Warning for lightning and gusty outflow winds, which is in effect

from 9 AM this morning to 5 PM PDT this afternoon.



* AFFECTED AREA...Fire Weather Zone 659 West Slopes of the 

  Central Cascades Generally above 1500 Feet.



* LIGHTNING...Scattered thunderstorm coverage is possible across 

  the Central Cascades.



* OUTFLOW WINDS...Any storms that develop will be capable of 

  gusty and erratic outflow winds between 20 and 30 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.
