According to the National Weather Service, a Fire Weather Watch from late Tuesday night through Thursday afternoon. A weather system digging into the Great Basin region will create gusty north to east winds over portions of interior Northern
California Wednesday and Thursday. Daytime minimum relative humidity values will be very low along with extremely poor overnight recoveries Wednesday night. These will lead to critical fire weather conditions for the northern Coastal Range and foothills, the Sacramento Valley, portions of the northern San Joaquin Valley, and the Northern Sierra Nevada and foothills below 7000 feet.

Caltrans is preparing for widespread power outages as well. They remind motorists that non-working (dark) and flashing red traffic signals be treated as all-way stops during power outages. Drivers should proceed with caution through intersections and observe right-of-way rules.

Throughout District 3, traffic signals contain battery backups, which typically last 3 to 4 hours before becoming non-operational. Additional measures may be implemented at signals during power outages including generators or stop signs. However, motorists should be prepared for all-way stops at non-lighted signals during power outages.
