Planned Outlook

Planned Actions
Construct direct and indirect line as conditions and opportunities allow. Hold, patrol, improve, and mop-up existing containment lines. Perform hazard tree abatement, and suppression repair.
Projected Incident Activity
12-hour time frame:
Heavier burning fuels may have potential to retain heat and create flare ups. Fire growth will be minimal. Suppression repair efforts are underway in areas of the fire that are no longer posing a potential risk of escape.

24-hour time frame:
Conditions will trend warm and dry allowing finer, smaller fuels to dry. Any heavier fuels with remaining heat will have potential to rekindle and create flare ups. Fire growth will be minimal. Suppression repair efforts are underway in areas of the fire that are no longer posing a potential risk of escape.

Weather Synopsis

Weather Concerns
An upper level trough over the Pacific Northwest will move into the Great Basin during the next few days while an upper level ridge will gradually build toward California. This will lead to continued dry weather with temperatures a degree or 2 cooler on Thursday compared to Wednesday, but still near normal. As the system over the northwest moves further east, ridgetop wind gusts will slacken. Afternoon rh should trend higher for Thursday into the 25 to 32 percent range. However, temperatures moderate for Friday and remain a few degrees above normal into early next week as the ridge gradually builds into Northern California.

Skies were clear and sunny. After a start in the low to mid 60s, temperatures rose into the mid 70s to low 80s. Humidity peaked late on Tuesday evening and then fell into the 20 to 30% range in most locations overnight. Humidity changed little the rest of the day, with min rh generally in the 19 to 26% range. Wind were southeast to south at 3 to 7 mph on the ridges and down canyon 3 to 6 mph during the morning, with afternoon ridge winds a bit breezy from the southwest at 5 to 10 mph with gusts to 19 mph and up canyon 4 to 8 mph.

Mostly sunny to sunny weather continues as high pressure dominates. Highs will again be near normal on Thursday, ranging in the mid 70s to low 80s. Afternoon humidity is expected to range from 25 to 32% on Thursday. Light easterly ridge winds are anticipated on Thursday morning, with southwest to west ridge winds gusting up to 14 mph during midday to early afternoon. Winds will be lighter to end the week as a ridge of high pressure gradually builds toward the area. Temperatures will warm to the upper 70s to mid 80s for Thursday to Sunday with afternoon gusts from the southwest to west up to 12 mph. Rh should bottom out in the 20s each afternoon.
