The California Interagency Incident Management Team 16 assumed command of the fire at 7 a.m. this morning.

A Temporary Flight Restriction is in place over the fire. Residents and visitors are reminded that Unmanned Aircraft Systems are not permitted in or around fire areas.

Warm and dry conditions are expected through the weekend. Winds will be light, with typical breezy afternoon and evening winds Sunday and Monday. Unusually dry air will remain over the region through Sunday, resulting in low afternoon humidity and poor overnight recovery for the mid slopes and ridges. The possibility of thunderstorms returns Wednesday onward.

Update 2:40 p.m. Friday: The R1 Ranch Fire has increased to 3,340 acres and is 35 percent contained this afternoon, according to InciWeb. The increase in acreage is attributed to more accurate aerial mapping.

More favorable weather and lighter winds led to more moderate fire behavior on Aug. 30.

Planned actions involved continuing direct and indirect line construction from anchor points and using parts of Horse Lake Road as containment line.

There is potential for the fire to spread east and northeast toward Horse Lake Flat.

Because of increasing complexity, a Type 2 incident management team, California Team 16, will assume management of the fire on Saturday, Aug. 31
