   1019 AM CDT TUE SEP 27 2016

   VALID 271700Z - 281200Z

   ...PORTIONS OF SOUTHERN CALIFORNIA...
   CURRENT SURFACE OBSERVATIONS REVEAL HIGHER ELEVATION SITES WITH RH
   VALUES IN THE TEENS TO LOW 20S AND WIND GUSTS OVER 20 MPH. THE BEST
   JUXTAPOSITION OF STRONG WINDS AND LOW RH VALUES IS CURRENTLY IN THE
   SANTA YNEZ RANGE NEAR SBA WHERE WIND GUSTS OVER 30 MPH ARE BEING
   REPORTED AMIDST RH VALUES OF 14 AND 15 PERCENT. THESE ELEVATED TO
   LOCALLY CRITICAL CONDITIONS WILL CONTINUE ACROSS THE REGION THROUGH
   LATE MORNING. THE STRONGEST WINDS THIS AFTERNOON WILL BE OVER
   ELEVATED PORTIONS OF SAN DIEGO AND RIVERSIDE COUNTIES BUT INCREASING
   MOISTURE SHOULD HELP TEMPER THE OVERALL FIRE WEATHER POTENTIAL. NO
   CHANGE IS NEEDED TO THE PREVIOUS OUTLOOK.

   SOUTHERN CALIFORNIA...WHILE RIDGING TO ITS NORTH SLOWLY SLIDES
   EASTWARD ACROSS THE NORTHERN GREAT BASIN TOWARDS THE CENTRAL

   06Z OBSERVATIONS EXHIBIT POCKETS OF ELEVATED FIRE-WEATHER CONCERNS
   ACROSS TERRAIN-FAVORED LOCATIONS OF SOUTHERN CALIFORNIA...AND THESE
   CONDITIONS SHOULD PERSIST PAST 12Z. FOLLOWING SUNRISE...RH VALUES
   WILL FALL INTO THE TEENS/20S IN MANY LOCATIONS...WHILE POCKETS OF
   SUSTAINED WINDS AROUND 15-20 MPH CONTINUE. GIVEN VERY DRY
   FUELS...THESE METEOROLOGICAL CONDITIONS WILL SUPPORT ELEVATED
   CONCERNS THROUGH PART OF THE AFTERNOON. THEREAFTER...A WEAKENING SFC
   PRESSURE GRADIENT AND IMPROVED OVERNIGHT RH RECOVERY SHOULD FURTHER
   DIMINISH THE FIRE-WEATHER THREAT.
