The Valley Fire was very active Sunday especially on the east side where it spread across Lyons Valley Road. At 9:19 p.m. Sunday the head of the fire was four miles east of the road, it had skirted across the north end of Barrett Lake, and was four miles northwest of the dam at Lake Morena. Much of the growth of the blaze was in the Lawson Valley and Carveacre areas.
On Sunday firefighters held the spread to 408 acres, bringing the total to 10,258. The military has been activated, adding an additional six helicopters to the fire suppression efforts.
The forecasted cooler and lighter winds Monday should provide a slight reduction of fire spread. However, there are a lot of dead fuels that will continue to be receptive to fire spread. Santa Ana winds are expected to develop Tuesday and continue through Wednesday with gusts over 40 mph.
Evacuations are in effect. San Diego County has more information.

When the Valley Fire was reported in San Diego County south of Alpine, California at 2:16 p.m. Saturday the temperature at the nearby U.S. Forest Service Japatul Fire Station was 113 degrees and the relative humidity was 8 percent. It spread rapidly to the west running south of Japatul Road toward Loveland Reservoir pushed by winds gusting to 20 mph, prompting evacuations. Late in the afternoon CAL FIRE said it was 1,500 acres; an overnight update from fire officials estimated it at 3,000 acres. Structures have burned, but the number has not been released.
Evacuations are in effect. San Diego County has more information.
The weather forecast for the Valley Fire area is not good news for firefighters, with Sunday’s forecast calling for 108 degrees, 10 percent humidity, and ridgetop winds out of the northeast at 15 mph. On Monday it will cool off — to 99 degrees with 20 percent humidity. The mountain areas of southern California on Sunday are under two warnings: Excessive Heat and Red Flag.
The fire is under unified command, with Incident Commanders Chris Anderson (U.S. Forest Service) and Kurt Zingheim (CAL FIRE).
According to the satellite heat data, much of the Valley Fire is burning in an area that has not been visited by fire since the huge Laguna Fire of 1970. But the northwest side has spread into the Viejas Fire of 2001, as you can see in the map below.
