Gusty northeast winds are expected to continue through much of this week, but should remain below wind advisory levels. Relative humidities will continue to remain in single or low teens as well with poor overnight recoveries. The gusty offshore winds, very low relative humidity, unseasonably warm temperatures, and extremely dry fuels will allow the extreme fire danger to continue. The greatest concern will be the Los Angeles and Ventura county mountains, Santa Clarita, and the Santa Ana wind prone areas of the Ventura County valleys and Oxnard Plain. If these conditions develop, there will be the potential for large fires, rapid fire growth, and extreme fire behavior if ignition occurs. Although there are no Red Flag Warnings issued for Santa Barbara County, there will be local north to northeast winds 15 to 25 mph around the hills above Montecito over the next couple of evenings bringing some elevated fire concerns.
Unhealthy air quality once again today due to thick smoke and ash fall from the Thomas Fire. The biggest impacts will be felt in Santa Barbara and southwest Ventura Counties, but also smoky conditions are expected over western San Luis Obispo County and possibly across West Los Angeles as well. Take precautions when outdoors like wearing a protective mask and recirculate interior air when driving. Drink more water during dry and smoky conditions.
