Red Flag Warning issued June 20 at 3:29PM PDT until June 22 at 9:00AM PDT by NWS Sacramento CA

Effective: Fri June 20, 2025, 3:29 PM
Expires: Sat June 21, 2025, 4:00 PM

* Winds...North winds 10 to 20 mph with gusts up of 30 to 40 mph. Strongest winds expected across the Sacramento Valley along and west of Interstate 5, the Delta, and the northern San Joaquin Valley. * Humidity...Minimum daytime humidity: 15 to 25 percent. Overnight recoveries in the mid 40s to mid 50s. * Highest Threat...Sacramento Valley along and west of the I- 5 corridor, adjacent Coastal Range, and the northern San Joaquin Valley. * Impacts...The combination of gusty winds and low humidity can cause fire to rapidly grow in size and intensity. Outdoor burning is not recommended. *

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.
