By Monday evening the fire had ballooned to 60,000 acres – an increase of 15,500 acres during the course of the day – with containment up to 5 percent, according to Cal Fire.
Cal Fire’s evening report on the County fire, which began on Saturday near Guinda in Yolo County before spreading into Napa County, said it is now threatening 700 structures.
So far, none of those structures have been reported destroyed or damaged, and no injuries have occurred, according to Cal Fire.
As of Monday evening, Cal Fire said the incident had not crossed into Lake County.
Radio traffic indicated another busy day on the incident for firefighters.
During the afternoon, the fire was reported to have crossed over containment lines north of Lake Berryessa.
Structure protection also was reported to be going on around the fire area, as the flames approached buildings that were identified as hunting cabins.
Winds were not reported to have been as high in recent days; on Monday afternoon they were said to be in the single digits, from the south southwest.
The winds are forecast to pick up overnight, at which time relative humidity – which aids firefighting – is expected to rise, based on radio reports.
With firefighters working in difficult terrain, there is still high potential for more fire growth, Cal Fire said.
More resources joined the firefighting effort on Monday. Cal Fire reported that 2,115 personnel, 177 engines, 51 water tenders, 12 helicopters, 51 hand crews and 50 dozers, plus numerous air tankers, were working the incident.
