.FIRE WEATHER...
RED FLAG WARNINGS IN EFFECT FOR MUCH OF LOS ANGELES AND VENTURA
COUNTIES THROUGH FRIDAY AS A MODERATE TO STRONG SANTA ANA WIND EVENT
AFFECTS SOUTHWEST CALIFORNIA. THE PEAK IN WIND SPEEDS IS OCCURRING
THIS MORNING...WITH GUSTS OF 65 TO 75 MPH OVER THE INTERIOR PEAKS OF
LA COUNTY...AND VALLEY LOCATIONS SEEING GUSTS OF 40 TO 60
MPH...STRONGEST IN THE SANTA CLARITA VALLEY AND THE EASTERN VENTURA
VALLEYS. GUSTS TO 45 MPH HAVE BEEN OBSERVED AS FAR WEST AS THE
VENTURA COUNTY COAST NEAR CAMARILLO. RELATIVE HUMIDITIES ARE VERY
LOW WITH MANY VALUES IN THE MID TO LOWER SINGLE DIGITS OBSERVED
ACROSS THE AREA. IN ADDITION...FUELS IN THE AREA ARE EXTREMELY DRY
FOR THIS TIME OF THE YEAR...AT VALUES THAT ARE MORE TYPICAL FOR MID
TO LATE SUMMERTIME. THE COMBINATION OF STRONG WIND GUSTS...LOW
HUMIDITIES AND VERY DRY FUELS HAS CREATED THE POTENTIAL FOR EXTREME
FIRE BEHAVIOR.

SURFACE PRESSURE GRADIENTS ARE BEGINNING  TO EASE SLIGHTLY ACROSS
THE AREA...WHICH SHOULD ALLOW THE OFFSHORE WINDS TO BEGIN TO
DIMINISH ACROSS THE AREA BY EARLY THIS AFTERNOON. ALONG THE
IMMEDIATE COAST...ONSHORE WINDS HAVE BEEN OBSERVED IN SOME LOCATIONS
AND THERE IS A CHANCE THAT THE WEST TO SOUTHWEST FLOW WILL SPREAD
INLAND ACROSS THE COASTAL PLAIN OF LA AND VENTURA COUNTIES THIS
AFTERNOON INTO THIS EVENING. THE SOUTHWEST FLOW IS FORECAST BY THE
NAM12 MET GUIDANCE TO GUST UP TO AROUND 25 MPH. THE COASTAL WINDS
WILL SHIFT BACK TO OFFSHORE BY AROUND SUNRISE FRIDAY MORNING AND
INCREASE...BUT WITH LOWER SPEEDS THAN WHAT HAS BEEN OBSERVED TODAY.
HOWEVER...IN SPITE OF THE LOWER WINDS SPEEDS...VERY DRY CONDITIONS
AND EXTREME FIRE DANGER WILL CONTINUE THROUGH FRIDAY AFTERNOON.
HUMIDITY RECOVERIES OVERNIGHT WILL BE POOR IN MOST
AREAS...ESPECIALLY WHERE EXPOSED TO OFFSHORE WIND THROUGH THE NIGHT.
HUMIDITIES WILL FALL QUICKLY TO THE SINGLE DIGITS AGAIN FRIDAY
MORNING...WITH MINIMUM READINGS OF 5 PERCENT OR LOWER.

BY EARLY AFTERNOON A MORE WIDESPREAD WIND SHIFT TO THE SOUTHWEST TO
WEST IS EXPECTED. THIS WILL ALLOW HUMIDITIES TO BEGIN TO RISE ACROSS
A LARGER PORTION OF THE COASTAL PLAIN...AND THIS MAY ADVANCE INLAND
TO THE COASTAL VALLEYS OVERNIGHT.

&&

.AVIATION...02/2350Z...GENERALLY HI CONFIDENCE IN THE CURRENT TAFS
