High winds and dry conditions that pose fire hazards have prompted weather forecasters to issue a Red Flag warning for the East Bay hills and the North Bay.
Warm temperatures are predicted for the Bay Area, according to the National Weather Service.
The warning period began at 10 p.m. Monday and is in effect until 8 a.m. Thursday, weather service officials said.
Gusts are expected to reach up to 40 mph at high elevations.
Red Flag warnings are alerts indicating that conditions are ideal for wildfires and the potential of rapid spreading.
Humidity levels are expected to reach between 10 to 20 percent at night and drop down between 5 to 10 percent during the day, according to weather officials.
The Danville area showed the lowest rainfall in recent years during 2013, with just 5.87 inches of rain recorded, and the weather service is predicting drought conditions to continue until March.
Mount Diablo recorded 6.56 inches of rain in 2013, more than 2 inches less than the previous record of 8.91 inches set in 1976. The normal average there is more than 25 inches annually.
