Full Notification

The National Weather Service in Seattle has issued a Red Flag Warning for lightning and gusty outflow winds, which is in effect from 1 AM to 11 PM PDT Thursday. The Fire Weather Watch is no longer in effect.

* AFFECTED AREA...Fire Weather Zone 652 West Portion of the Olympic Mountains, 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.

* LIGHTNING...Scattered thunderstorm coverage in the Cascades and Olympic mountains. Timing on thunderstorm development will be early Thursday morning and again in the afternoon and evening.

* OUTFLOW WINDS...Any storms that develop will be capable of gusty and erratic outflow winds between 35 and 50 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. Very warm weather Friday into next week increases the chances of increased fire activity on potential new starts from Thursday's lightning activity.

* AFFECTED AREAS: WEST PORTION OF THE OLYMPIC MOUNTAINS ... WEST SLOPES OF THE NORTH CASCADES GENERALLY ABOVE 1500 FEET ... WEST SLOPES OF THE CENTRAL CASCADES GENERALLY ABOVE 1500 FEET ... EAST PORTION OF THE OLYMPIC MOUNTAINS

Instructions:

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.
