Update July 5, 2018: As of the morning of July 5, the wildfire has grown to 86,000 acres, with 30% of it contained, according to the latest update from Cal Fire. Cal Fire said it expects to have full containment July 10.
"Firefighters will continue to work aggresively through the day to build containment lines around the County Fire. Steep and inaccessible terrain has created difficulty for firefighters on the Northern end of the fire. The fire burned throughout the night with little recovery from the relative humidity. The weather will become hotter and drier into the weekend and fire growth potential remains high," reads a Cal Fire press release.
July 2, 2018: Communities in northern California are facing mandatory evacuations and road closures as firefighters work to contain wildfires that are spreading across three counties and nearly 45,000 acres.
Cal Fire said it is on scene with 12 helicopters, having contained only 3% of the fire as of 10 a.m. local time Monday. Local media reports are describing the fires as "fast-moving," having begun over the weekend June 30 and continuing to grow this week due to wind, high heat and low humidity.
The fires originated in Yolo County Saturday and have since spread into Napa and Lake counties, Cal Fire said. The agency has issued mandatory evacuations for affected communities.
