A particularly late-season frontal system brought strong winds to the coast and Coast Range.
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 PQR wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
248 AM PDT FRI APR 2 2010
.SYNOPSIS...A PACIFIC LOW PRESSURE SYSTEM WILL MOVE THROUGH THE
FORECAST AREA LATE TONIGHT THROUGH EARLY SATURDAY BRINGING STRONG
WIND AND PRECIPITATION. ONSHORE FLOW BEHIND THE SYSTEM WILL KEEP SNOW
IN THE HIGHER TERRAIN INTO THE WEEKEND... WITH COOL SHOWERY
CONDITIONS PERSISTING IN THE LOWLANDS. ANOTHER WEAKER LOW
PRESSURE SYSTEM WILL LIKELY BRING MORE PRECIPITATION TO THE AREA
SUNDAY. AN ACTIVE WEATHER PATTERN CONTINUES NEXT WEEK WITH MODELS
SUGGESTING A SERIES OF FRONTS MOVING THROUGH THE PACIFIC NORTHWEST.
&&
.SHORT TERM...WATER VAPOR LOOP INDICATING CONTINUED DEVELOPMENT OF
APPROACHING STORM SYSTEM. 08Z SURFACE ANALYSIS PUTS CENTRAL PRESS
AROUND 990 MB LOCATED AT 46N 134W. SO FAR TRACK OF THE DEVELOPMENT
HAS BEEN MAINLY WEST TO EAST WITH A SLIGHT TURN TO THE NORTH IN THE
LAST HOUR OR SO. CURRENT HEADING IS TOWARD THE SOUTH WA COAST THEN
WILL MAKE A TIGHTER TURN TO THE NORTH AS IT MATURES AND MOVES TOWARD
VANCOUVER ISLAND THIS MORNING. FORECAST MINIMUM PRES WITH THIS LOW
RANGE FROM 977 MB TO 986 MB BY THE NAM AND GFS RESPECTIVELY.
PEAK WIND ON THE COAST BETWEEN 6 AND 10 AM THIS MORNING. ALSO
PRESSURE RISES FOLLOWING THE COLD FRONT WILL BRING CONTINUED WINDY
CONDITIONS WELL INTO THE AFTERNOON. HIGH WIND WARNING CONTINUES FOR
THE COAST...COAST RANGE AND WILLAPA HILLS. SOME WIND WILL FIND ITS
WAY FURTHER INLAND AS UNSTABLE AIR MASS ALONG WITH PRESSURE RISES
FOLLOWING THE COLD FRONT ARRIVE AROUND MIDDAY AND CONTINUE THROUGH
THE AFTERNOON. WIND WARNINGS AND ADVISORIES CONTINUE.
MODEL PRECIPITATION FORECAST IS A LITTLE LESS WITH THE LATEST GFS AND
NAM RUNS. ALSO HAS A BULLS EYE OF HEAVIER PRECIPITATION HEADED TO
NORTHERN CA. SNOW LEVEL FORECAST LOOKS OKAY SO WILL CONTINUE WITH
WARNINGS AND ADVISORIES BUT TWEAK AMOUNT DOWN A LITTLE. GUSTY WINDS
IN THE MOUNTAINS WILL STILL MAKE FOR REDUCED VISIBILITIES IN BLOWING
SNOW. WIDESPREAD SNOW TOTALS IN THE RANGE OF 1-2 FEET IN THE CASCADES
STILL LOOK REASONABLE...ESPECIALLY ABOVE THE PASSES WHERE SOME SPOTS
MAY RECEIVE CLOSER TO 3 FEET BY SATURDAY MORNING. CASCADE
FOOTHILLS...COAST RANGE AND UPPER HOOD RIVER WILL ALSO GET A LESSER
SHARE TODAY AND TONIGHT.
OROGRAPHICS BEHIND THE COLD FRONT LOOK GOOD THROUGH FRIDAY NIGHT
WHICH WILL CAUSE AN EXTENDED PERIOD OF SNOW IN THE CASCADES. SNOW
SHOWERS SHOULD DECREASE OVER THE CASCADES AS WESTERLY FLOW SLOWLY
BREAKS DOWN SATURDAY MORNING. HOWEVER THE AIR MASS WILL LIKELY REMAIN
FAIRLY COOL ALOFT...ALLOWING SHOWERS TO PERSIST INTO SATURDAY.
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...MID RANGE
MODELS KEEP AN ACTIVE WEATHER PATTERN OVER THE FORECAST AREA THROUGH
THE EXTENDED FORECAST PERIOD. A FRONTAL SYSTEM IS SHOWN TO APPROACH
THE COAST LATE SUNDAY. RECENT MODEL RUNS BRING THE LOW CENTER INTO
THE OREGON COAST...PUSHING MOST OF THE PRECIPITATION TO THE SOUTH OF
THE AREA. STILL COULD SEE A GOOD DOSE WITH WRAP AROUND MOISTURE
EXPECTED...AND POST TROUGH SHOWERS ARE EXPECTED TO CONTINUE INTO
TUESDAY. THE LAST FEW OPERATIONAL RUNS OF BOTH THE GFS AND ECMWF HAVE
BEGUN TO HINT AT A BLOCKING RIDGE DEVELOPING BY MID WEEK NEXT
WEEK...WHICH WOULD KEEP ANY ADVANCING SYSTEMS TO OUR NORTH. GIVEN THE
VARIABILITY OF MODELS AT THIS TIME RANGE WILL NEED TO KEEP AN EYE ON
THIS POSSIBILITY. BROWN
&&
.AVIATION...PREVAILING CIGS TO LOWER IN ADVANCE OF NEXT FRONTAL
SYSTEM COMING IN...LIKELY TO END UP IN MVFR CATEGORY ALONG THE COAST
AND LOW END OF VFR CATEGORY INLAND WHEN THE HEAVIER RAIN ARRIVES
AFTER 12Z-15Z TODAY. CIGS SHOULD BE EXPECTED TO TEMPORARILY DIP
INTO MVFR RANGE ALSO INLAND. MODERATE RAIN MAY ALSO DROP
VISIBILITIES DOWN INTO MVFR RANGE. STRONG SOUTH WINDS TO PEAK
WITH THE PASSAGE OF A COLD FRONT BETWEEN 15Z-22Z...LATEST AT
INLAND SITES.
KPDX AND APPROACHES...VISIBILITIES IN RAIN MAY DROP FLIGHT
CATEGORY TO MVFR BETWEEN 13Z AND 20Z...WITH SLIGHTLY LESSER
CHANCES FOR CIGS TO DROP INTO MVFR RANGE.
&&
.MARINE...WIND WAVE DRIVEN SEAS WILL DEVELOP QUICKLY EARLY TODAY
AS SOUTHERLY WINDS INCREASE TO STORM FORCE AHEAD OF THE COLD
FRONT...ROUGHLY BETWEEN 6 AM AND 10 AM. HISTORICALLY SUSTAINED
WINDS PEAKING AROUND 40 KTS WOULD BE EXPECTED TO PRODUCE SEAS OVER
20 FT...SO GOING ABOVE WW3 MODEL GUIDANCE STILL LOOKS LIKE A
REASONABLE FORECAST. MODEL CONTINUES TO BUILD WESTERLY SWELL FROM
THE GULF OF ALASKA TONIGHT...WHICH SHOULD KEEP SEAS NEAR 20 FT
INTO SAT.

4 high wind. Local standard time, as filed.
The strong peak gust was reported by equipment at Cape Foulweather early in the morning. High sustained winds of 37 kt were reported on Clatsop Spit a little later in the morning.
The peak wind gust was recorded by equipment on Mt. Hebo. Because the anemometer was frozen during the majority of this event, this peak gust probably occurred after the peak of the winds moved through. Start and end times were estimated.
The strong peak wind gust was recorded in Lincoln City. High winds were also reported in other places along the coast: peak winds of 44 kt with gusts to 63 kt on the Yaquina Bridge along Hwy. 101 in Newport; peak winds of 46 kt with gusts to 55 kt on the Siuslaw Jetty near Florence; peak winds of 44 kt with gusts to 51 kt in Newport.
The strong peak wind gust was recorded by the Rockhouse RAWs equipment.
