A small system brought winds strong enough to just reach high wind criteria along the Oregon coast.
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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
825 AM PDT MON APR 5 2010
.SYNOPSIS...AN UPPER LEVEL TROUGH WILL MOVE EAST ACROSS THE REGION
TODAY INTO THIS EVENING. A WEAK FRONTAL SYSTEM WILL MOVE ACROSS THE
AREA TUE. A WEAK WARM FRONT MAY BRUSH THE SOUTH WA COAST WED AS AN
AREA OF HIGH PRES BUILDS INTO THE REGION. THE NEXT COLD FRONT WILL
PUSH THROUGH THE REGION LATER WED NIGHT AND THU.
&&
.SHORT TERM...BANDS OF SHOWERS CIRCULATING AROUND THE LOW OFF OF THE
COAST WILL SPREAD INLAND TODAY AS THE LOW OPENS UP INTO A NEGATIVE
TILT TROUGH AND SHIFTS INLAND LATE THIS AFTERNOON AND EVENING. THERE
HAVE BEEN SCATTERED LIGHTNING STRIKES OVER THE COASTAL WATERS AT
TIMES...SO WILL KEEP A MENTION OF TSTMS NEAR THE COAST TODAY. WILL
ALSO PUT IN CHANCE OF TSTMS INLAND THIS AFTERNOON AND EARLY EVENING.
LOOKS MARGINAL...BUT AM SOUNDINGS LOOK SOMEWHAT FAVORABLE FOR TSTMS.
ENSUING ONSHORE FLOW BEHIND THIS SYSTEM WILL KEEP A THREAT OF SHOWERS
GOING INTO TUE. IN ADDITION A PORTION OF A WEAK FRONTAL SYSTEM OUT
NEAR 50N/150W APPEARS TO DIG ESE INTO THE AREA EARLY TUE MAINTAINING
AN ENHANCED THREAT OF SHOWERS.
SHORT WAVE RIDGING BUILDS INTO THE AREA TUE NIGHT AND WED...BUT AN
APPROACHING WARM FRONT APPEARS TO BRUSH THE FAR NW SECTIONS WHERE
MOIST SW FLOW ALOFT CONTINUES. ELSEWHERE THE UPPER LEVEL RIDGING WILL
BRING PROBABLY THE NICEST DAY OF THE WEEK. CCDR/RW
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...AFTER THE
RIDGING ON WED...ECMWF DIVERGES FROM THE GFS AND GEM WITH A
CONSIDERABLY SLOWER TROUGH COMING IN THE SECOND HALF OF THE WEEK.
WITH GOOD AGREEMENT BETWEEN THE GFS AND GEM...WILL LEAN TOWARDS THEM
AND GO WITH RELATIVELY HIGH POPS FOR THE FRONT WED NIGHT AND THU.
BEYOND THU MODELS CONTINUE TO DIVERGE LEADING TO LOW CONFIDENCE...BUT
WITH GFS AND GEM TRENDING TOWARDS DRIER SCENARIOS...WILL TREND POPS
TO BE NEAR TO BELOW NORMAL FRI THROUGH SUN.
&&
.AVIATION...PREVAILING VFR CONDITIONS TODAY AND TONIGHT...ALTHOUGH
TEMPORARILY MVFR CIGS AND VISIBILITIES CAN BE EXPECTED WITH SHOWERS.
WITH THE COLD CORE UPPER LOW JUST OFF THE COAST CREATING AN UNSTABLE
AIR MASS...A LOW PROBABILITY EXISTS FOR THUNDERSTORMS AT THE COASTAL
TAF SITES.
KPDX AND APPROACHES...PREVAILING VFR CONDITIONS ARE EXPECTED THROUGH
TONIGHT. OCCASIONAL SHOWERS MAY BRING A FEW PERIODS OF MVFR
CONDITIONS.
&&
.MARINE...A TROUGH OF LOW PRES OFF THE WA AND OREGON COAST WILL MOVE
ACROSS THE COASTAL WATERS TODAY. WINDS WILL PERIODICALLY REACH INTO
SMALL CRAFT CATEGORY TODAY AND TONIGHT AS THE WINDS TURN FROM THE S
TO THE W. W SWELL WILL SUBSIDE SLOWLY THROUGH WED...EXPECTED TO
DROP DOWN TO ABOUT 10 FT...BEFORE BUILDING AGAIN TO THE TEENS AS
MORE SWELL ARRIVES FROM THE GULF OF AK.
A WARM FRONT WILL BRUSH THE WATERS TUE AND TUE NIGHT...BUT IS
UNLIKELY TO KEEP WINDS IN SMALL CRAFT CATEGORY. A STRONG COLD FRONT
WILL BARREL ACROSS THE WATERS WED NIGHT AND THU.
&&
.PQR WATCHES/WARNINGS/ADVISORIES...
OR...NONE.
WA...NONE.
