Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS LOX wrote it up.
Another round of gusty Santa Ana winds affected Southern California. The strongest winds were reported across the mountains of Los Angeles county.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Los Angeles, CA wrote its last area forecast discussion before the first event at Nov 23, 10:40 AM PST, 3 hours 57 minutes earlier.
SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA 1040 AM PST FRI NOV 23 2007 ...STRONG SANTA ANA WIND EVENT EXPECTED FOR MUCH OF LOS ANGELES AND VENTURA COUNTIES THIS AFTERNOON THROUGH SATURDAY... ...CRITICAL FIRE WEATHER CONDITIONS FOR MOST OF VENTURA AND LOS ANGELES COUNTIES THIS AFTERNOON THROUGH SUNDAY AFTERNOON... .SHORT TERM... SATELLITE IMAGERY INDICATING QUICK BURNOFF OF LOW CLOUDS ACROSS THE COASTAL AND VALLEY AREAS THIS MORNING AS INVERSION WAS QUITE WEAK. LATEST OBS BEGINNING TO SHOW WEAK TO MODERATE OFFSHORE WINDS BEGINNING TO DEVELOP ACROSS THE LA/VTU COUNTY MOUNTAINS AND A FEW VTU COUNTY VALLEY SITES. STRONG OFFSHORE WINDS STILL LOOK ON TRACK FOR THIS AFTERNOON FOR THE MOUNTAINS OF LA/VTU COUNTIES. WATER VAPOR IMAGERY ALSO SHOWS GOOD SUBSIDENCE BEGINNING TO MOVE ACROSS THE REGION THIS MORNING. WINDS WILL QUICKLY STRENGTHEN THIS AFTERNOON. AS STRONG UPPER LEVEL SUPPORT DEVELOPS OVER THE REGION. WENT AHEAD AND TURNED HIGH WIND WATCHES INTO HIGH WIND WARNINGS FOR LA/VTU COUNTY VALLEYS AS WELL AS THE COASTAL AREAS FROM THE HOLLYWOOD HILLS TO MALIBU BEGINNING THIS EVENING AND CONTINUING THROUGH SATURDAY AFTERNOON BEFORE WINDS BEGIN TO DIMINISH SOME SATURDAY NIGHT. LATEST 12Z WRF MODEL RUN INDICATED STRONG DOWNWARD MOTION FROM 700 MB TO THE SURFACE ACROSS THE LA/VTU COUNTY MOUNTAINS AND VALLEYS THROUGH TOMORROW AFTERNOON. WITH GOOD COLD AIR ADVECTION...FEEL CONFIDENT THAT WRF MODEL IS REASONABLE. THEREFORE THE UPGRADE TO HIGH WIND WARNINGS IN AREAS MENTIONED. A WIND ADVISORY WILL BE ISSUED FOR THE VENTURA COASTAL PLAIN...BUT WILL HAVE TO BE MONITORED IN CASE WINDS INCREASE TO WARNING CRITERIA OVERNIGHT. ...FROM PREVIOUS DISCUSSION... THE MAIN STORY WILL BE THE WIND EVENT UNFOLDING TODAY...ESPECIALLY ACROSS LOS ANGELES AND VENTURA COUNTIES...WITH INCREASINGLY CRITICAL FIRE WEATHER CONDITIONS. A VIGOROUS VORT WAS CURRENTLY DROPPING SWD ACROSS NRN CA. THIS WILL CONT TO DROP SWD TODAY...AND WINDS THRU THE ATMOSPHERE WILL STRENGTHEN SHARPLY ACROSS THE REGION LATER THIS MORNING AND THIS AFTERNOON. A 115 KNOT JET WILL NOSE INTO NERN L.A. COUNTY THIS AFTERNOON...AND AS WIDESPREAD AND POWERFUL SUBSIDENCE SPREADS ACROSS THE AREA...STRONG WINDS WILL SPREAD INTO LOWER LEVELS OF THE ATMOSPHERE LATER TODAY AND TONIGHT. THE WRF SHOWS 850 MB WINDS INCREASING TO 45 TO 50 KT ACROSS THE MTNS OF L.A. AND ERN VTU COUNTIES THIS AFTERNOON...AND TO 55 TO 60 KT TONIGHT AND SAT MORNING. STRONG WINDS SHOULD BECOME WIDESPREAD IN THE MTNS OF L.A. AND VTU COUNTIES THIS AFTERNOON. WINDS SHOULD INCREASE RATHER QUICKLY...SO ALTHOUGH THERE MAY BE A PERIOD OF TIME WITH JUST ADVISORY LEVEL WINDS...HAVE DECIDED TO JUST UPGRADE TO HIGH WIND WARNINGS ACROSS THE MTNS STARTING THIS AFTERNOON. IT SHOULD TAKE A BIT LONGER FOR THE WINDS TO SURFACE IN THE SANTA MONICA MOUNTAINS...BUT WITH 950 MB WINDS FCST TO REACH 50 KNOTS ACROSS L.A. COUNTY BY MIDNIGHT...BLV WARNING LEVELS WINDS ARE LIKELY THERE...SO JUST STARTED THE WARNING THIS EVENING RATHER THAN THIS AFTERNOON. WIND GUSTS COULD REACH 70 TO 75 MPH IN THE MOUNTAINS OF VENTURA AND LOS ANGELES COUNTIES DURING THE PEAK OF THE EVENT TONIGHT/SAT MORNING. WITH THE WRF SHOWING 55 TO 60 KT WINDS AT 950 MB...HIGH WIND WARNING LEVEL WINDS WILL PROBABLY BE REACHED IN MOST VALLEY LOCATIONS. HOWEVER...DUE TO A BIT OF UNCERTAINTY AS TO HOW WIDESPREAD THEY WILL BE IN THE VLYS...HAVE DECIDED TO LEAVE THE HIGH WIND WATCHES IN PLACE...ALLOWING THE DAY SHIFT A CHANCE TO SEE ONE MORE MODEL RUN...SATELLITE IMAGERY OF THE SUBSIDENCE...AND DEVELOPING WINDS IN THE MTNS. BASED ON VERY IMPRESSIVE ISENTROPIC CROSS SECTIONS...WAS CONSIDERING ISSUING HIGH WIND WATCHES FOR CSTL SXNS OF VTU COUNTY AND CSTL SXNS OF L.A. COUNTY BELOW PASSES AND CANYONS FROM MALIBU TO HOLLYWOOD... BUT WINDS WILL PROBABLY REMAIN JUST UNDER THE CRITERIA FOR WARNING...(SUSTAINED 40 MPH WINDS OR FREQUENT GUSTS TO 60 MPH.) HOWEVER...IT IS A NEAR CERTAINTY THAT WIND ADVISORIES WILL BE NEEDED IN THOSE AREAS. FREEZING TEMPS IN THE ANTELOPE VALLEY AND AREAS OF FROST IN THE INTERIOR VLYS OF SLO COUNTY AND THE CUYAMA VLY WILL END BY MID MORNING SUNSHINE WARMS THE LAND. HOWEVER...WITH SO MUCH COLD AIR ADVECTION ACROSS THE REGION...TEMPS WILL BE ON THE COOL SIDE ACROSS THE FCST AREA TODAY...DESPITE THE DEVELOPING OFFSHORE FLOW. ALTHOUGH THE NELY DIRECTION OF THE WINDS WILL BE LESS FAVORABLE FOR WDSPRD STRONG WINDS IN THE MTNS OF SBA COUNTY...WINDS COULD STILL REACH ADVISORY LEVELS IN THAT AREA FOR A WHILE TONIGHT INTO EARLY SAT. FIRE WEATHER CONDITIONS COULD APCH CRITICAL LEVELS IN THE SBA COUNTY MTNS AS WELL...AND IT IS POSSIBLE THAT RED FLAG WARNINGS MAY HAVE TO BE EXPANDED INTO THAT AREA AS WELL. WINDS SHOULD BEGIN TO DIMINISH BY LATE SAT AFTERNOON. HOWEVER...FLOW REMAINS OFFSHORE SAT NIGHT INTO SUN MORNING...AND ADVISORY LEVEL WINDS ARE POSSIBLE AGAIN...AT LEAST IN THE MTNS. LOW LEVEL GRADS MAY ACTUALLY FLIP ONSHORE SUN AFTERNOON AS A FAST MOVING UPPER TROUGH APCHS THE CST. HOWEVER...IT SHOULD REMAIN VERY DRY ACROSS THE AREA INTO SUNDAY AFTERNOON...MAINTAINING CRITICAL FIRE WEATHER CONCERNS ACROSS L.A. AND VTU COUNTIES. MODELS SHOW AN UPPER TROUGH DIGGING SWD ACROSS THE ERN PAC SUN NIGHT AND MONDAY. AT THIS TIME...IT APPEARS THIS SYSTEM WILL REMAIN TOO FAR TO THE SW OF THE AREA TO PRODUCE MORE THAN A RETURN TO ONSHORE FLOW...SOME COOLING...AND POSSIBLY SOME INCREASE IN CLOUDINESS ACROSS THE REGION. .LONG TERM...ANOTHER UPPER TROUGH IS FCST TO DROP FROM THE PAC NWS INTO THE GREAT BASIN TUE INTO WED...BUT MODELS HAVE TRENDED A BIT FLATTER WITH THIS SYSTEM. ANOTHER SYSTEM MOVING INTO THE W CST MAY DIG A BIT FARTHER W THU...POSSIBLY BRINGING ANOTHER ROUND OF GUSTY WINDS LATE IN THE WEEK...BUT MODELS ARE IN POOR AGREEMENT WITH THAT SYSTEM...SO CONFIDENCE IS LOW. OVERALL...LOOKS LIKE GENERALLY COOL WEATHER ACROSS THE AREA TUE THRU THU...WITH COLD OVERNIGHT POSSIBLE ACROSS INTERIOR SECTIONS AND EVEN CSTL SXNS OF SLO AND SBA COUNTIES MUCH OF THE WEEK. && .FIRE WEATHER...23/1200Z RED FLAG WARNINGS HAVE ALREADY BEEN POSTED FOR THE MOUNTAINS AND VALLEYS OF LOS ANGELES COUNTIES...VALID FROM THIS AFTERNOON THROUGH SUNDAY AFTERNOON. AS OFFSHORE WINDS BEGIN TO INCREASE SHARPLY THIS AFTERNOON...LOOK FOR HUMIDITY VALUES TO LOWER QUICKLY IN THE MOUNTAINS AND VALLEYS...WITH MANY AREAS FALLING TO BETWEEN 10 AND 15 PERCENT. DURING THE PEAK OF THIS STRONG SANTA ANA WIND EVENT TONIGHT INTO SATURDAY MORNING...WIDESPREAD HUMIDITY VALUES BETWEEN 5 AND 15 PERCENT CAN BE EXPECTED ACROSS THE WARNING AREA. WHILE THE WINDS ARE EXPECTED TO DIMINISH CONSIDERABLY BY LATE SATURDAY AFTERNOON...THERE WILL LIKELY BE LINGERING LOW HUMIDITIES IN THE MOUNTAINS AND VALLEYS THROUGH SUNDAY AFTERNOON. HUMIDITY RECOVERIES TONIGHT AND SATURDAY NIGHT ARE EXPECTED TO BE VERY POOR. THE COMBINATION OF STRONG WINDS...VERY LOW HUMIDITIES...AND VERY DRY FUELS WILL CAUSE CRITICAL RED FLAG CONDITIONS IN THE MOUNTAINS AND VALLEYS. IT APPEARS INCREASINGLY LIKELY THAT CRITICAL FIRE WEATHER CONDITIONS WILL AFFECT CSTL SXNS OF VTU COUNTY AND L.A. COUNTIES (FROM MALIBU TO THE HOLLYWOOD HILLS)...AND RED FLAG WARNING WILL LIKELY BE ISSUED FOR THOSE AREAS AS WELL. GUSTS TO 50 MPH ARE POSSIBLE IN WIND FAVORED LOCATIONS ALONG WITH SINGLE DIGIT HUMIDITIES TONIGHT INTO SUNDAY MORNING. HUMIDITIES ARE EXPECTED TO RISE MORE QUICKLY ALONG THE COAST ON SUNDAY AFTERNOON AS ONSHORE TRENDS BEGIN. PLEASE REFER TO THE LATEST RED FLAG WARNING PRODUCT (LAXRFWLOX) FOR MORE DETAILS. .AVIATION...23/1800Z SOME LINGERING STRATUS AND HAZE ACROSS THE COASTAL AND VALLEY TAFS LATE THIS MORNING. WITH INCREASING OFFSHORE WINDS EXPECTD THIS AFTERNOON...EXPECT ANY VSBYS RESTRICTIONS TO CLEAR OUT BY EARLY THIS AFTERNOON. FOR THIS AFTERNOON THROUGH SATURDAY MORNING...RATHER SIGNIFICANT OFFSHORE WINDS ARE EXPECTED. WILL BE SOME GUSTY NORTH TO NORTHEAST WINDS AT THE USUAL LOCATIONS SUCH AS KVNY AND KBUR. ALSO WITH STRONG WINDS ABOVE THE SURFACE...WIND SHEAR AND TURBULENCE WILL BE AN ISSUE THROUGH THE TAF PERIOD. KLAX...HIGH CONFIDENCE IN VFR CONDS THROUGH THE TAF PERIOD.
