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.
The combination of an upper level disturbance and strong onshore gradients produced strong and damaging winds across Southern California, especially across southern Santa Barbara county, the mountains of Ventura and Los Angeles counties and the Antelope Valley. The gusty winds knocked down trees and power lines, producing widespread power outages across sections of Los Angeles county and a damaging wildfire in the Beverly Glen area. Across the coastal waters off of Ventura, Los Angeles and Orange counties, large wind waves and a combination of large northwest and south swell produced very hazardous conditions. At Newport Beach, two individuals were swept off of a jetty and drowned as a result of the large waves. In Ventura county, two individuals were rescued off of Ventura Pier when they jumped into the water on a bet.
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 Apr 10, 4:50 AM PST, 3 hours 10 minutes earlier.
SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA 550 AM PDT TUE APR 10 2007 ...UPDATED AVIATION AND MARINE SECTIONS... .SHORT TERM (TODAY-THURSDAY)...BEST THERMAL GRADIENTS HAVE ALREADY OCCURRED ASSOCIATED WITH THE CURRENT WIND EVENT. PRESSURE GRADIENTS ARE STILL DEVELOPING...SO ADVISORIES WILL BE CONTINUED A LITTLE FURTHER. THERMAL GRADIENTS COULD REDEVELOP TONIGHT. NAM- WRF TIME HEIGHT SECTIONS DO NOT LOOK PARTICULARLY IMPRESSIVE ALONG WITH NAM-WRF AND GFS SURFACE PRESSURE GRADIENTS. IT WILL BE A REAL CLOSE CALL WHETHER ADVISORIES WILL NEED TO BE EXTENDED. BASED ON THE CURRENT THOUGHTS AT THIS TIME...MORE EMPHASIS WOULD BE PLACED ON EXTENDING THE MOUNTAIN ADVISORIES...AND DROPPING THE DESERT AND SANTA BARBARA COUNTY ADVISORIES LATER TODAY. THE BEST APPROACH IS THE WAIT AND SEE METHOD TO ALLOW MODELS TIME TO ADJUST. MODELS SEEM TO BE DOING A RELATIVELY GOOD JOB OVER THE LAST COUPLE DAYS IN PICKING UP ON WIND EVENT. BETTER WIND EVENT...AND POSSIBLY WARNING TYPE EVENT APPEARS TO BE TAKING SHAPE FOR THE SANTA BARBARA SOUTH COAST...ANTELOPE VALLEY...AND SOUTHERN CALIFORNIA MOUNTAIN AREAS ON THURSDAY. GOOD 950...850...AND 700 MB THERMAL GRADIENTS ARE DEVELOPING THURSDAY AFTERNOON AS INSIDE SLIDER DROPS SOUTH ALONG THE CALIFORNIA-NEVADA BORDER. PRESSURE GRADIENTS ARE NOT PARTICULARLY STRONG...BUT TRENDS INDICATED ARE MODERATE TO STRONG OFFSHORE ESPECIALLY BETWEEN KSBA-KSMX...KSBA-KBFL...AND KLAX-KTPH. MAIN PROBLEM APPEARS TO BE THE AMOUNT OF MOISTURE ARRIVING WITH THE STORM THOUGH. OUTSIDE OF WIND EVENTS...COASTAL EDDY SPIN UP IS BEING DELAYED DUE TO LOWER-LEVEL FLOW PATTERN BEING MORE NORTHERLY THAN NORTHWESTERLY. WHILE ENOUGH MOMENTUM EXISTS...WIND DIRECTION IS NOT THAT FAVORABLE FOR EDDY FORMATION. AS A RESULT...MARINE LAYER HAS BEEN PUSHED SOUTH INTO EXTREME SOUTHWESTERN CALIFORNIA AND THE SOUTHERN PORTION OF LOS ANGELES COUNTY. MORE CLEARING WILL TAKE PLACE THIS AFTERNOON AS MARINE INTRUSION IS RATHER THIN OVER THE AREA. ANY FOG AND STRATUS THAT OCCURS WILL BE RATHER SHORT-LIVED THIS MORNING AND WILL LIKELY BREAK UP ALMOST IMMEDIATELY AFTER SUNRISE. EDDY SPIN UP SHOULD FINALLY OCCUR WEDNESDAY AFTERNOON AS A MORE NORTHWEST COMPONENT DEVELOPS. GFS AND NAM-WRF SOLUTIONS AGREE AS 850 MB MIXING INCREASE RATHER RAPIDLY IN THE NORTHWEST FLOW. MARINE THICKNESS COULD VARY BASED UPON HOW LONG THE AREA IS EXPOSED TO THE NORTHWEST COMPONENT AND HOW FAST THE EDDY SPINS UP. FOR NOW...MARINE LAYER IS TAKEN TO THE LOS ANGELES COUNTY COASTAL SECTIONS AND SPILLS OVER INTO THE SAN GABRIEL VALLEY BUT COVERAGE WILL LIKELY BE MORE EXTENSIVE. APPROACHING COLD FRONT FINALLY ARRIVES WEDNESDAY MORNING ALONG THE CENTRAL COAST. PRECIPITATION APPEARS TO BE SHOWERY...AND PRECIPITATION WILL NOT AMOUNT TO MUCH...MAYBE A FEW HUNDREDTHS OR LESS WITH LOCALLY HIGH AMOUNTS ON NORTHWEST FACING SLOPES. FRONT DIES SOUTH OF POINT CONCEPTION. DRIZZLE COULD OCCUR WITH THE FRONT SOUTH OF POINT CONCEPTION...BUT WITH THE EDDY SPINNING UP JUST BARELY AHEAD OF THE FRONT...DRIZZLE ASSOCIATED WITH THE FRONT IS NOT LIKELY. A SECONDARY AND WEAK SURFACE FEATURE DROPS SOUTH THURSDAY WITH THE STORM SYSTEMS UPPER-LEVEL SUPPORT. THIS SHOULD BE WHEN THE THE WIND EVENT PICKS UP STEAM. SOME ADDITIONAL PRECIPITATION COULD OCCUR ALONG THE CENTRAL COAST AND POSSIBLY SOUTH OF POINT CONCEPTION...BUT AMOUNTS WILL LIKELY BE A TENTH OR LESS WITH LOCALLY HIGH AMOUNTS ON THE NORTHWEST FACING SLOPES. MAIN THREAT IS THE WINDS FOR AREAS OF CALIFORNIA. .LONG TERM (FRIDAY-MONDAY)...LOWER-LEVEL FLOW PATTERN TURNS OFFSHORE FRIDAY THROUGH SATURDAY KEEPING MOSTLY CLEAR CONDITIONS OVER THE CENTRAL COAST AND SOUTHERN CALIFORNIA. ANOTHER STORM SYSTEM IS POSSIBLE OVER THE WEEKEND. 00Z ECMWF IS TRENDING TOWARDS THE IDEAS OF THE 00Z GFS OF POSSIBLE MAJOR STORM SYSTEM FOR SOUTHERN CALIFORNIA OVER THE WEEKEND AND INTO THE WORK WEEK NEXT WEEK. GFS IS CERTAINLY THE MOST AGGRESSIVE WITH SYSTEM BRINGING A COLD AIR MASS SOUTH. GFS SOLUTIONS INDICATES BROAD AREA OF WARM AIR ADVECTION OUT AHEAD OF THE FRONT WITH GOOD LOW-LEVEL SOUTHERLY FLOW ASSOCIATED WITH THE TROUGH BEHIND THE FRONT. THE GFS SOLUTION COULD BE OVERDONE THOUGH. GFS FREQUENTLY STRUGGLES WITH SPRING STORM SYSTEMS THIS TIME OF YEAR AS THE POLAR JET BECOME MORE VARIANT. HOWEVER...THE ECMWF STRUGGLES MORE OFTEN RELATIVE TO THE GFS IN THIS TYPE OF PATTERN...FORECAST HEDGES TOWARDS GFS SOLUTION WITH PARTLY CLOUDY SKIES AND NEGLIGIBLE POPS. && .AVIATION...10/1250Z... EDDY FORMATION HAS BEEN RELUCTANT THIS MORNING LEAVING CLEAR SKIES AND VFR CONDITIONS AT ALL AIRFIELDS IN THE AREA. KLAX AND KLGB MAY SEE IFR CIGS BEFORE SUNRISE...BUT CONFIDENCE IS LOW. MODERATE NW WINDS ARE EXPECTED N OF POINT CONCEPTION THIS AFTERNOON...SLIGHTLY GUSTIER THAN MONDAY. S OF POINT CONCEPTION...A USUAL SEABREEZE TO AROUND 10 KTS IS EXPECTED AT COASTAL AIRFIELDS. KPMD AND KWJF WILL EXPERIENCE STRONG NW WINDS TO 30 KT FOR MUCH OF THE DAY TODAY. KBUR WILL REMAIN CLEAR FOR THE DAY...WITH A SLIGHT CHANCE OF AN IFR CIG AROUND 008 BEFORE SUNRISE. OTHERWISE...USUAL SOUTHERLY WINDS WILL DOMINATE BY 20Z. KVNY IS EXPERIENCING SOME LLWS DUE TO GUSTY N WINDS ALOFT. IT IS LIKELY THIS WILL AVOID KBUR...BUT IT SHOULD BE KEPT IN MIND. && MARINE...10/1250Z... AS NW FLOW INCREASES OVER THE COASTAL WATERS...A LARGE NW SWELL WILL BUILD THROUGH THE WEEK. THIS WILL CREATE STRONG SMALL CRAFT TO GALE FORCE WIND CONDITIONS FOR THE OUTER WATERS AND POSSIBLY THE INNER WATERS FOR MOST OF THE WEEK. IN ADDITION...THE WAVE ENERGY WILL PROPAGATE TO THE BEACHES CREATING HIGH SURF ADVISORY AND ABOVE NORMAL SURF CONDITIONS FOR THE COASTLINE THROUGH FRIDAY. FURTHER COMPLICATING THE SITUATION IS A MODERATE SOUTH SWELL WHICH WILL BUILD THROUGH THE WEEK...CREATING HIGH RIP CURRENT RISK AT LOCAL BEACHES. && .LOX WATCHES/WARNINGS/ADVISORIES... CA...
