On Monday the spread of the 67,000-acre Valley fire 62 miles north of San Francisco was slowed by temperatures in the low 60s, relative humidity above 80 percent, and 0.01? of rain that fell in the late afternoon, according to data from a weather station south of the fire in Calistoga.
CAL FIRE reported Tuesday morning that their latest damage assessment shows that 585 homes and hundreds of other structures have been destroyed. The surveys are continuing and the numbers will likely change in the coming days. Approximately 9,000 structures are threatened. Evacuations are still in place, affecting 23,000 people.
In addition to the homes that burned in Middletown and Cobb, a geothermal plant that produces electricity, The Geysers, was damaged. Five of the 14 plants were affected, including power lines and wooden cooling towers.
Air tankers have not worked the fire since Saturday, grounded by poor visibility caused by smoke and clouds. Tuesdays weather is expected to make it possible to use them again. The forecast calls for a 35 percent cloud cover, a high temperature of 73 degrees, relative humidity in the 40s, and winds out of the west at 8 to 13 mph.
