...RED FLAG WARNINGS ALLOWED TO EXPIRE FOR MUCH OF LOS ANGELES 
AND VENTURA COUNTIES AT 10 AM TODAY...
...RED FLAG WARNING IN EFFECT FROM 2 AM TO 10 PM PST SATURDAY FOR
THE SANTA BARBARA COUNTY MOUNTAINS DUE TO GUSTY NORTH TO NORTHEAST
WINDS AND LOW RELATIVE HUMIDITY...
...FIRE WEATHER WATCH IN EFFECT FROM LATE LATE SATURDAY NIGHT
THROUGH SUNDAY EVENING FOR GUSTY NORTHEAST WINDS AND LOW RELATIVE
HUMIDITY FOR THE LOS ANGELES AND VENTURA COUNTY MOUNTAINS AND
VALLEYS...
.DISCUSSION...Offshore winds continue to weaken this morning allowing
for the expiration of the Red Flag Warnings for Los Angeles and
Ventura counties. 
After the passage of an upper level disturbance, there will be
increasing upper level wind support and cold air advection that will 
bring strengthening north to northeast winds across the mountains
and adjacent foothills of Santa Barbara county (including higher
elevations of the Thomas Fire) late tonight through Saturday evening,
with gusts of 30 to 40 mph being common. Due to the stronger winds
in the upper atmosphere, there is the potential for locally stronger
gusts across exposed ridgetops on Saturday. The combination of these
gusty winds with humidities generally ranging between 10 and 20 percent
will likely result in critical Red Flag conditions across the Santa
Barbara county mountains. As a result, there will be an increased
threat of very rapid fire spread, long range spotting, and extreme
fire behavior. Gusty north to northeast winds up to 30 mph will 
also filter down into the Santa Barbara south coast, which could 
bring significant impacts to lower elevations of the Thomas Fire. 
In addition, there will be increasing northerly winds on Saturday 
across the Ventura county mountains, especially near the Highway 
33 and Interstate 5 corridors.
