ORIGINAL (AP) - A wildfire that erupted amid hot, dry conditions and gusty winds in Sonoma County north of San Francisco sent residents fleeing from their homes.
The California Department of Forestry and Fire Protection says the Sawmill Fire in rural Cloverdale has charred about 1,500 acres of timber and dry brush.
Fire spokesman Paul Lowenthal said Sunday that about 90 people in 36 homes were under evacuation orders or advisories, and that the fire was threatening the Geysers geothermal facility.
One of the 14 plants has also been evacuated.
The San Francisco Chronicle reports that Calpine operates the facility and says all employees are safe.
Firefighters battling the blaze in steep terrain braced for another day of temperatures in the high 90s and strong winds on Monday.
The fire has burned about 2 square miles about an hour and a half north of San Francisco.
