Effective: Sat March 21, 2026, 7:20 AM

Strong southwest winds gusting up to 30 MPH will combine with near record or record warmth, low humidity, and dried vegetation to produce an Elevated Fire Danger today.

Use extra caution while operating outdoor equipment around dry vegetation and do not carelessly discard cigarettes.

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.
