Eureka, Calif. – Fire danger will increase significantly across parts of Northern California overnight into Monday as isolated dry thunderstorms threaten to ignite new wildfires in areas already vulnerable to rapid fire spread. Lightning with little rainfall, combined with erratic wind gusts up to 30 mph, could quickly create dangerous fire conditions.
According to the National Weather Service in Eureka, a Red Flag Warning is in effect from 9 p.m. Sunday until 6 p.m. Monday for Trinity County, northeast Humboldt County and southwest Siskiyou County. While the highest concentration of storms is expected across those counties, isolated thunderstorms could develop across much of the interior of northwest California.
Communities including Weaverville, Hayfork, Willow Creek, Orleans and Happy Camp are among the areas facing the greatest wildfire threat. Any lightning strike outside of heavier rainfall could spark new fires, and gusty, shifting winds may cause existing fires to spread rapidly.
The National Weather Service warns that erratic outflow winds from thunderstorms can develop suddenly, even several miles away from rainfall, making firefighting efforts more difficult. Residents should avoid outdoor burning, postpone activities that could create sparks and immediately report any signs of smoke or new fire starts to local authorities.
Outdoor recreationists should use extra caution, as conditions can change rapidly when thunderstorms develop. Campfires should be completely extinguished, and equipment capable of producing sparks should be used only with extreme care.
The Red Flag Warning remains in effect through 6 p.m. Monday, and additional fire weather alerts could be issued if thunderstorm coverage expands or fire danger persists. Residents should continue monitoring updates from the National Weather Service and local fire agencies throughout the event.
