Red Flag Warning until 06:00PM Friday.
Critical fire weather conditions are expected in the coming days over the Dolan and Glass Fires. Periods of moderate northerly winds will develop as early as Wednesday evening and last through Friday. This will combine with very low afternoon humidity and little or no nighttime recovery along with critically dry fuels. This wind event will NOT be as strong as the weekend event for the Glass Fire. However gusty winds and low humidity will create potentially dangerous fire weather conditions for the Dolan Fire, especially during the overnight hours when humidity tends to drop and ridge top winds can be strongest over the Los Padres National Forest. The National Weather Service in San Francisco has issued a Red Flag Warning...which is in effect from 1 PM Thursday to 6 PM PDT Friday. The Fire Weather Watch is no longer in effect.
* WIND...Northwest winds arrive Thursday afternoon during the peak of the burn period along with very low humidity. Northwest winds increase Thursday night into Friday morning with gusts to 25 mph and little or no humidity recovery. Breezy northerly winds continue through the Friday burn period as humidity stays very dry with continued hot temperatures.
* HUMIDITY...15 to 25 percent but locally 8-12 percent with little or no nighttime recovery in the hills.
* HIGHEST THREAT...Active portions of the Glass Fire or those areas with unsecured or open fire line.
* IMPACTS...Fire will spread rapidly due to the combination of hot temperatures, very dry fuels, breezy northerly winds and low humidity.
* AFFECTED AREAS: NORTH BAY MOUNTAINS
Instructions:
A Red Flag Warning means that critical fire weather conditions are either occurring now...or will shortly. A combination of strong winds...low relative humidity...and warm temperatures can contribute to extreme fire behavior.
