***CORRECTED HEADLINE FOR SANTA BARBARA AND SAN LUIS OBISPO COUNTIES***
...HIGH RISK FOR EXTREME FIRE BEHAVIOR WITH ANY NEW FIRE STARTS THURSDAY THROUGH FRIDAY DUE TO MODERATE TO LOCALLY STRONG SANTA ANA WINDS AND LOW RELATIVE HUMIDITY...
.Moderate to locally strong Santa Ana winds will quickly develop on Thursday, peak Thursday afternoon through Friday afternoon, then weaken through the weekend. Meanwhile, dry air will settle over the region and dry out any helpful effects of the recent rains. The previous Fire Weather Watches were upgraded to Red Flag Warnings. Some of the windiest areas may see Red Flag conditions linger into Saturday. As the winds expand Thursday Night into Friday, Red Flag conditions may form over the interior mountains of Santa Barbara and San Luis Obispo Counties on Friday, where a Fire Weather Watch is now in effect.
* AFFECTED AREA...The mountains of Los Angeles and Ventura Counties.
* TIMING...From 6 AM Thursday to 10 PM PDT Friday.
* WINDS...Northeast to east 20 to 40 mph with gusts of 50 to 70 mph.
* RELATIVE HUMIDITY...Minimums of 8 to 20 percent common.
* IMPACTS...If fire ignition occurs, conditions are favorable for extreme fire behavior which would threaten life and property.
