Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Jan 9, 2:30 PM PST, 5 hours 30 minutes before

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
230 PM PST SUN JAN 9 2005

SHORT TERM...A LARGE...UPPER LEVEL TROUGH IS ORIENTED NORTHEAST TO
SOUTHWEST OVER SEATTLE...WITH THE UPPER LEVEL LOW CENTERED ABOUT 450
NM WEST-SOUTHWEST OF SEATTLE. AHEAD OF THIS TROUGH...STRONG
SOUTHWEST WINDS ALOFT COVER THE ENTIRE STATE OF CALIFORNIA.
SIGNIFICANT STORM CENTERS CONTINUE TO ROTATE AROUND THE TROUGH AN
MOVE ONSHORE OVER CENTRAL AND SOUTHERN CALIFORNIA. AT THIS
TIME...THE LATEST IN A SERIES OF VIGOROUS SHORT WAVE TROUGHS IS
MOVING ONSHORE OVER CENTRAL AND SOUTHERN CALIFORNIA.

IN THE LAST 12 HOURS...OVER 4 INCHES OF RAIN HAS FALLEN AT BOTH SAN
MARCOS PASS IN THE SANTA YNEZ RANGE AND AT NORDHOFF RIDGE NEAR THE
TOPA TOPAS OF VENTURA COUNTY. BOTH RADAR AND SATELLITE DATA SHOW
THAT EVEN MORE HEAVY RAIN WILL INUNDATE THE REGION THIS AFTERNOON
THROUGH THE EVENING HOURS. THE LATEST NATIONAL WEATHER SERVICE
DOPPLER RADAR DATA SHOWS AREAS OF MODERATE TO HEAVY RAINS OVER MOST
OF VENTURA AND LOS ANGELES COUNTY...WITH THE COVERAGE OF SHOWERS
DIMINISHING AS YOU MOVE THROUGH SANTA BARBARA COUNTY AND INTO SAN
LUIS OBISPO COUNTY. HOWEVER...A SOLID REGION OF MODERATE TO HEAVY
SHOWERS IS FILLING THE RADAR OVER THE HORIZON TO THE SOUTHWEST. THE
LEADING EDGE OF THIS SOLID AREA OF RAIN IS NOW [145 PM] OVER THE
CHANNEL ISLAND...AND SHOULD MOVE ONSHORE BY 230 PM. SATELLITE DATA
SHOWS THAT THE LINE OF MODERATE TO HEAVY SHOWERS EXTENDS SOUTHWEST
OUT TO ABOUT 800 NM OF POINT CONCEPTION. THIS AREA OF SHOWERS AND
THUNDERSTORMS WILL MOVE THROUGH EASTERN SANTA BARBARA...VENTURA...
AND LOS ANGELES COUNTIES THROUGH THE NIGHT.

SATELLITE DATA INDICATES THAT RAINFALL RATES IN THE HEAVIEST STORMS
OVER THE WATER ARE CURRENTLY RUNNING IN EXCESS OF AN INCH AN HOUR.
THIS RATE WILL LIKELY JUMP TO AROUND 1.5 INCHES PER HOUR WHEN THE
HEAVIEST SHOWERS MOVE ONSHORE. SUCH RATES COULD LAST ONE OR MORE
HOURS WHEN THE BANDS MOVE ONSHORE LATER THIS AFTERNOON AND EVENING.
THIS WILL ONLY ADD TO THE NUMEROUS FLOODING PROBLEMS THE REGIONS IS
CURRENTLY ENCOUNTERING.

THE VERY HEAVY RAINS WITH THIS SYSTEM HAVE PRODUCED WIDESPREAD URBAN
AND SMALL STREAM FLOODING WITH NUMEROUS MUDSLIDES SHUTTING PORTIONS
OF KEY ROADWAYS INCLUDING THE 33...154...126 AND 138. IT IS LIKELY
THAT THE CONTINUED HEAVY RAINS WILL RESULT IN ADDITIONAL
MUDSLIDES...ESPECIALLY ALONG THE PCH IN THE MALIBU AREA. SOME RIVERS
ARE ALSO OVER THEIR BANKS...SUCH AS THE LOWER VENTURA RIVER NEAR THE
101. THE SANTA CLARA RIVER HAS ALSO SEEN SOME PROBLEMS IN THE
VICINITY OF FILLMORE AND SANTA PAULA. INTERESTS ALONG ALL STREAMS
AND RIVERS NEED TO KEEP ABREAST OF THE LATEST FLOOD WARNINGS AND
ADVISORIES.

HEAVY SHOWERS SHOULD TAPER OFF LATER TONIGHT OVER MOST OF THE
REGION...BUT LINGER OVER PORTIONS OF LOS ANGELES COUNTY INTO MONDAY
MORNING. LOOK FOR A BREAK IN THE HEAVIEST SHOWERS ON MONDAY...BUT A
MORE VIGOROUS SYSTEM WILL BEGIN TO MOVE ONSHORE LATE MONDAY AND
TUESDAY. IN CONTRAST TO THIS CURRENT SYSTEM...TUESDAYS STORM SHOULD
MOVE THROUGH THE REGION MUCH QUICKER...WHICH IS GOOD. HOWEVER...IT
LOOKS LIKE IT COULD BE MORE DYNAMIC WITH BANDS OF THUNDERSTORMS...
HEAVY DOWNPOURS...SMALL HAIL...AND POSSIBLE WATERSPOUTS.

SNOW LEVELS ARE VERY HIGH TODAY...ABOVE 7000 FEET...WHERE SNOW IS
EXPECTED TO BE MEASURED IN FEET. SNOW LEVELS WILL REMAIN HIGH ON
MONDAY...BUT DROP QUICKLY TO AROUND 4500 FEET JUST AFTER MIDNIGHT ON
TUESDAY MORNING. WE ARE KEEPING THE WINTER STORM WARNING IN EFFECT
THROUGH TUESDAY MORNING DUE TO THE VERY HEAVY SNOW EXPECTED ABOVE
7000 FEET TODAY AND THE LOWERING SNOW LEVELS MONDAY NIGHT AND
TUESDAY MORNING.

SHOWERS SHOULD DIMINISH MOST AREAS ON TUESDAY AS THE STORM PASSES
AND THE WINDS TURN TO THE NORTHWEST AND BECOME GUSTY. ALONG THE
CENTRAL COAST AND MOUNTAINS THE SHOWERS MAY LINGER LONGER...THROUGH
TUESDAY EVENING...DUE TO THE ONSHORE NORTHWESTERLY FLOW BEHIND THE
STORM SYSTEM.

LAX AVIATION...EAST WINDS ARE STILL A PROBLEM THROUGH THIS EVENING.
ALSO...THERE IS THE POTENTIAL FOR SOME VERY HEAVY SHOWERS AND
THUNDERSTORMS.

EXTENDED...MEDIUM RANGE MODELS IN GOOD AGREEMENT THROUGH FRIDAY
BEFORE DIVERGING. LOOK FOR SOME DRY WEATHER IN THE EXTENDED PERIOD
BEGINNING WEDNESDAY THROUGH THE WEEK. THE GFS IS SUGGESTING A CUT
OFF LOW OFF THE COAST OF CALIFORNIA THIS WEEKEND...BUT IT DOES NOT
LOOK LIKE THIS WILL BE A MAJOR WEATHER MAKER AT THIS TIME. SO...IF
YOU CAN WAIT UNTIL WEDNESDAY...IT LOOKS LIKE WE WILL GET A FEW DAYS
TO DRY OUT.
