Wind: North to northeast 10 to 25 mph with local gusts up to 35 to 40 mph. Strongest winds expected west of Interstate 5 and into the Coastal Range, and through favorably oriented gaps and canyons in the foothills.
Humidity: Minimum daytime humidity in the single digits or teens. Areas of poor to moderate overnight humidity recovery only to 25 to 30 percent.
Impacts: Any fires that develop will likely spread rapidly. Outdoor burning is not recommended.
Additional Details: Increasing northerly winds later tonight is forecast to lower humidity mainly west of I-5 and through locally favored gaps and canyons in the lower elevations. Conditions expected to develop over areas east of I-5 during the day on Saturday.
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.
