Red Flag Warning issued June 18 at 7:56PM PDT until June 19 at 7:00PM PDT by NWS Sacramento CA

Effective: Thu June 18, 2026, 7:56 PM
Expires: Fri June 19, 2026, 7:00 PM

The National Weather Service in Sacramento has issued a Red Flag Warning for thunderstorms and strong outflow winds, which is in effect from 5 AM to 7 PM PDT Friday. * Affected Area...Fire Zone 121 W. Shasta County Above 3000 ft, Fire Zone 122 W. Shasta County 1000-3000 ft, Fire Zone 123 Shasta Lake Area & 1-5 1000-3000 ft, Fire Zone 124 Shasta Metro, Fire Zone 125 Shasta County Foothills 1000-3000 ft, Fire Zone 126 E. Shasta /S. Cascades Above 3000 ft and Fire Zone 127 Burney Basin. * Thunderstorms...Wet and dry thunderstorms with abundant lightning. * Outflow Winds...Gusts up to 40 mph. * Impacts...Lightning from isolated dry thunderstorms or outside of the main precipitation core in wet thunderstorms can create new fire starts and may combine with strong outflow winds to cause a fire to rapidly grow. Confidence is low on exact coverage and wet vs dry, but latest forecast has increased thunderstorm potential overall.

A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
