A powerful Pacific storm smashed ashore along the Oregon, Washington, and British Columbia coasts Monday, bringing hurricane force winds, torrential rains, and widespread flooding to the coast. Wind gusts over hurricane force (74 mph) were common along the coast, and one location, the aptly named Destruction Island in Washington, had sustained hurricane force winds (74 mph), with gusts to 93 mph. Winds gusting to 76 mph generated seas up to 48 feet high off the Oregon coast, and buoy 46050, 23 miles west of Newport, was torn from its mooring by 40 foot seas. Debris flow warnings have been posted for the steep mountain areas of the Oregon Coast Range near Tillamook. Debris flows are dangerous rapidly moving landslides. Rainfall amounts exceeding ten inches in the past day and a half have been measured in the North Oregon Coast Range. Rainfall amounts over a foot were estimated by the Seattle and Portland, OR radar (Figure 1).

The forecast
The storm, with a central pressure of 965 mb, is expected to move ashore Tuesday morning over the British Columbia coast and weaken. The strongest winds and heaviest rain have already past for the coast, but the inland Cascade Mountain range will see another 4-6 inches of rain by Tuesday afternoon. Flooding is possible Tuesday on all the rivers in western Washington and Oregon.

When I woke up this morning there was a good two feet of snow welcoming me! It's still coming down right now! I ♥ SNOW!
Bear Creek floods and covers the trail.

Wow, was this ever a Pineapple Express!! Hope things settle down in the Northwest for a while...this flooding is bad enough. Winds were incredible on parts of the OR coast. We've been out to Cape Meares...wouldn't want to be there with 114 mph gusts!!
A pair of storms that slammed into the Pacific Northwest had much of the region under water Tuesday, leaving five people dead, thousands without power and major highways shut down
Well done article... They got slammed.
Big wave surfer dies at famed Ghost Trees surf spot
By RON HARRIS
SAN FRANCISCO
A big wave rider died Tuesday at the unforgiving surf break known as Ghost Trees, a Monterey County spot known for its fast-moving 20-foot and better waves.
Peter Davi, 45, of Monterey, lost his surfboard and was attempting to swim to shore, but never made it, witnesses told authorities. Friends of Davi lost sight of him and later found him floating in the water unconscious.
New report ranks U.S. teens 29th in science worldwide
"What once was the gold standard [for international education] is now not even at the OECD average, which shows you how much the world has changed," says Andreas Schleicher, who helped write the report. The US is average in the number of students at the highest levels of scientific literacy, but has a much larger pool – nearly 1 in 4 – at the bottom, Mr. Schleicher notes. "We have stand-alone studies that suggest these kids have grim prospects in the labor market," he says.
TROPICAL CYCLONE 04F DAMAN [CAT 1]
12.3ºS 177.2ºE - 40 knots 990 hPa
Tropical Disturbance Advisory #1
==========================
Tropical Cyclone Daman [990 hPa] reported centered at 12.3S 177.2E as of 0600 UTC. Cyclone is intensifying with expected sustained winds of 40 knots close to the center increasing to 50 knots in the next 6 to 12 hours.
Expect Gale Winds within 90 miles of the center in the eastern semi-circle.
Low Level Circulation Center just northeast of Rotuma. Overall organization good. Convective tops cooling over central feature. Outflow good to north and south. Dvorak Based on 0.7 wrap on LOG10 Spiral, yielding a Dvorak Intensity of 3.0. PAT agree but MET remains at 2.5, thus T3.0/3.5/D1.5/24 HRS.
System lies just south of a 250 hPa outflow axis downstream of an approaching short wave upper trough. Cyclone Daman is being steered west-southwest by a mid level ridge to the southeast. It is expected to gradually turn southward and last southeast in the next 12 to 24 hours. Global models agree on this track projection with some intensification
Forecast position and Intensity

13.1S 175.3E 45 kts
14.6S 174.8E 50 kts
Special Weather Bulletin for Rotuma
====================================
Expect winds over Rotuma to be damaging gale force with average wind speeds to 40 knots and momentary gusts to 55 knots. Frequent heavy rain and squally thunderstorms. Sea flooding of low lying coastal area expected.
Gale Warning remains in force for Rotuma
The following information is provided especially for the mariner: Expect damaging gale force winds within 90 miles of center. Very Rough to high Seas with damaging heavy swells are likely.
There is plenty Pacific weather going on recently, with grief and hardship in the Maritimes apparently. Not nice.
The good news is, that there is a load of moisture in the Atlantic, heading my way, and we could use some of that rain here.
With luck, it will fill my new 1000 gal. watertank that I put up last week, before the dryseason arrives, " officialy ". Its been a dry wet season.
I'll keep my fingers crossed for you.
BBL to see whats going on. You have a good one today...

and said the GOES-12 maneuver will be extended until further notice
because they are having
problems coming out of the maneuver.
*UPDATE: GOES-12 (EAST) Anomaly is still ongoing, we are not receiving
GOES-12 (EAST) data until further notice. We are taking in FULL DISK
images on GOES-11 (WEST) until the problem is resolved.
NOTE: Low Cloud Base Data to AWIPS is unrelated to the GOES-12 Anomaly.
Work is being done to resolve the problem as soon as possible.
UPDATE: GOES-12 (EAST) Anomaly is still ongoing. Problem is still being
investigated.
*****_UPDATE J-DATE 339 1230 UTC_: GOES-12 (EAST) Anomaly is still
