Weak to Moderate Santa Ana winds will persist into Friday this week over primarily wind prone areas of Los Angeles and Ventura Counties. Northeast winds will be gusty at times with peak wind gusts of 20 to 40 mph Tuesday, increasing to 40 mph to 60 mph on Thursday. San Luis Obispo County will be windy on Thursday, with gusts from 20 to 40 mph expected. In addition, humidities will be 8 to15 percent, dropping to 2 to 9 percent for Thursday and Friday. These strong winds combined with low humidities and hot temperatures peaking in the 90s will mean the area will experience brief critical fire danger through Wednesday, peaking on Tuesday. By Thursday, widespread critical fire danger is likely over Santa Ana wind prone areas. These conditions mean there is a potential for rapid fire growth and extreme fire behavior if ignition occurs.
