Dispatch Area Discussion...
346 PM PST TUE NOV 24 2009
...DISCUSSION FROM LOS ANGELES/OXNARD...
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.
...DISCUSSION FROM MONTEREY...
HIGH PRESSURE WILL COVER THE AREA THROUGH THURSDAY THEN WEAKEN.
LIGHT OFFSHORE WINDS TODAY WILL WEAKEN THURSDAY. AN EASTERN PACIFIC
TROUGH WILL ARRIVE FRIDAY SPREADING A FEW SHOWERS OVER NORTHERNMOST
CALIFORNIA. HIGH PRESSURE WILL QUICKLY REBUILD BEHIND THE TROUGH AND
COVER THE AREA THROUGH THE WEEKEND AND EARLY NEXT WEEK.
NOTE : ALL WINDS ARE 20-FOOT WINDS UNLESS OTHERWISE SPECIFIED.
THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS.
