346 PM PST TUE NOV 24 2009
 STRONG OFFSHORE FLOW CONTINUES AS HIGH PRESSURE  REMAINS ANCHORED
 OVER THE GREAT BASIN. GUSTY WINDS AND VERY LOW  HUMIDITIES ARE
 EXPECTED TO CONTINUE RIGHT ON THROUGH THURSDAY  MORNING, WITH THE
 LOW HUMIDITIES LASTING THROUGH THURSDAY EVENING.  THE STRONGEST
 WINDS WILL OCCUR TODAY AND WEDNESDAY ACROSS VENTURA  AND LOS ANGELES
 COUNTIES, WITH SOMEWHAT LESS WIND ON THANKSGIVING  DAY. OVERNIGHT
 HUMIDITY RECOVERIES WILL BE POOR ACROSS THOSE AREAS  AS WELL. AFTER
 COORDINATION WITH LOCAL AGENCIES, A RED FLAG WARNING  HAS NOT BEEN
 ISSUED DUE TO LIVE FUEL MOISTURES BEING ABOVE CRITICAL  LEVELS.
 HOWEVER, DEAD FUEL MOISTURES ARE EXTREMELY LOW AND BECAUSE  OF THIS
 THERE IS STILL A VERY HIGH FIRE DANGER. THE SITUATION WILL  BE
 CLOSELY MONITORED AND THE POTENTIAL STILL EXISTS FOR A RED FLAG 
 WARNING TO BE POSTED FOR THIS EVENT SHOULD IT BE DETERMINED THAT THE
  FUELS ARE DRY ENOUGH TO SUPPORT IT.
 OFFSHORE FLOW WILL WEAKEN RAPIDLY THANKSGIVING DAY AS A LOW PRESSURE
  AREA APPROACHES THE AREA FROM THE WEST. ALTHOUGH NO PRECIPITATION
 IS  EXPECTED LOCALLY FROM THIS SYSTEM, IT WILL USHER IN MUCH COOLER 
 TEMPERATURES AND HIGHER HUMIDITIES TO THE AREA STARTING FRIDAY AS 
 ONSHORE FLOW RETURNS.
 THE RETURN TO ONSHORE FLOW WILL BE EXTREMELY BRIEF AS SURFACE HIGH 
 PRESSURE QUICKLY BUILDS OVER THE GREAT BASIN FRIDAY NIGHT INTO 
 SATURDAY. THIS WILL BRING ANOTHER ROUND OF GUSTY SANTA ANA WINDS TO 
 THE AREA WITH HUMIDITIES AGAIN DROPPING TO BELOW CRITICAL LEVELS. 
 INITITALLY TEMPERATURES WILL BE QUITE A BIT COOLER THAN THE CURRENT 
 OFFSHORE WIND EVENT DUE TO THE COLD AIR FROM FRIDAY`S LOW PRESSURE 
 SYSTEM. HOWEVER, THE HUMIDITY AND WIND COMPONENT OF THE RED FLAG 
 WARNING SYSTEM WILL LIKELY BE MET OVER THE WEEKEND AND POSSIBLY INTO
  MONDAY AS WELL. ISSUANCE OF ANY WATCHES OR WARNINGS WILL REQUIRE 
 COORDINATION WITH AGENCIES AND INPUT ON FUEL CONDITIONS.
