 ...GUSTY NORTHEAST WINDS AND VERY LOW HUMIDITIES TO CONTINUE THROUGH 
 THANKSGIVING DAY...
 
 ...MORE GUSTY WINDS AND LOW HUMIDITIES EXPECTED FOR THE WEEKEND...
 
 .DISCUSSION...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.
