WHATCOM COUNTY, Wash. — Forecasters in the Seattle office of the National Weather Service today issued a red flag warning for the west slopes of the north Cascades above 1,500 feet from 2am on Wednesday, August 10th, to 2am on Thursday, August 11th. Red flag warnings alert to increased risk of fire danger.
The warning is due to possible dry thunderstorms and gusty outflow winds.
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.National Weather Service red flag warning (August 9, 2022)
