...POTENTIAL FOR VERY STRONG AND DAMAGING OFFSHORE WINDS
WEDNESDAY NIGHT INTO EARLY FRIDAY ACROSS PORTIONS OF SOUTHWEST
CALIFORNIA...
A MAJOR CHANGE IN THE WEATHER PATTERN IS EXPECTED TO TAKE PLACE ON
WEDNESDAY AS A COLD UPPER LEVEL LOW PRESSURE SYSTEM DIVES
SOUTHWARD INTO THE GREAT BASIN. FROM WEDNESDAY NIGHT INTO
THURSDAY...THERE IS STILL UNCERTAINTY IN THE EXACT TRACK OF THIS
UPPER LEVEL LOW PRESSURE SYSTEM. IF THIS LOW PRESSURE SYSTEM REMAINS
TO OUR EAST...AS MOST COMPUTER MODEL SIMULATIONS CURRENTLY
INDICATE...THERE WILL BE THE POTENTIAL FOR A VERY STRONG AND
WIDESPREAD OFFSHORE WIND EVENT ACROSS SOUTHWEST CALIFORNIA. IN
FACT...KEY WEATHER FACTORS ARE COMING TOGETHER THAT COULD MAKE THIS
THE STRONGEST OFFSHORE WIND EVENT WE HAVE SEEN IN THE PAST FEW YEARS.
THE PEAK OF THIS OFFSHORE WIND EVENT WOULD LIKELY BE LATE WEDNESDAY
NIGHT INTO EARLY FRIDAY. THE STRONGEST OFFSHORE WINDS WILL LIKELY
BE FOCUSED THROUGH THE PASSES AND CANYONS OF LOS ANGELES AND
VENTURA COUNTIES. WHILE IT IS STILL A BIT EARLY TO PINPOINT EXACT
WIND SPEEDS WITH THIS EVENT DUE TO THE UNCERTAINTY IN THE TRACK OF
THIS LOW PRESSURE SYSTEM...THERE IS THE POTENTIAL FOR DAMAGING
WIND GUSTS OF 80 MPH OR GREATER THROUGH FAVORED MOUNTAIN PASSES...AND
60 MPH OR GREATER ACROSS WIND FAVORED COASTAL AND VALLEY
LOCATIONS. WEAKER OFFSHORE WINDS ARE EXPECTED TO CONTINUE THROUGH
THE WEEKEND.
IF THIS STRONG OFFSHORE WIND EVENT DEVELOPS...THERE WOULD LIKELY
BE SUFFICIENTLY LOW HUMIDITIES TO CREATE HIGH FIRE DANGER CONCERNS
ACROSS PORTIONS OF OUR FORECAST AREA. OTHER POTENTIAL IMPACTS WOULD
INCLUDE DOWNED TREES AND POWER LINES...AS WELL AS REDUCTIONS IN VISIBILITY
DUE TO BLOWING DUST AND SAND. MOTORISTS...ESPECIALLY THOSE
OPERATING HIGH PROFILE VEHICLES...SHOULD CLOSELY MONITOR UPDATES
ON THIS POTENTIAL STRONG WIND EVENT...AS TRAVEL CONDITIONS COULD BECOME
HAZARDOUS LATER THIS WEEK.
IT MUST BE EMPHASIZED THE EXACT TRACK OF THIS UPPER LEVEL LOW
PRESSURE SYSTEM WILL HAVE A SIGNIFICANT IMPACT ON THE MAGNITUDE OF THIS
OFFSHORE WIND EVENT. IN FACT...THERE IS STILL A CHANCE THAT THIS UPPER
LOW COULD DIG WESTWARD CLOSER TO OUR FORECAST AREA...WHICH WOULD KEEP
THE STRONGEST WINDS OFF THE COAST...AND BRING MORE MOISTURE INTO
THE REGION.
PLEASE STAY TUNED TO THE LATEST NATIONAL WEATHER SERVICE FORECASTS AND
STATEMENTS ON THIS DEVELOPING WEATHER SITUATION.
