OF AMCHITKA TONIGHT. AS THE SYSTEM MOVES EAST IT WILL REMAIN SOUTH OF
THE ALEUTIANS. WINDS WILL SHIFT TO THE NORTHEAST WITH GUSTS TO 80 MPH
ACROSS THE WESTERN ALEUTIANS BEFORE DIMINISHING TO BELOW WARNING
CRITERIA TUESDAY AFTERNOON.

REMEMBER...A HIGH WIND WARNING MEANS HAZARDOUS WEATHER CONDITIONS ARE
IMMINENT OR HIGHLY LIKELY. PEOPLE ARE URGED TO SECURE LOOSE OBJECTS
THAT COULD BE BLOWN AROUND OR DAMAGED BY THE WIND.

THE NEXT STATEMENT IS SCHEDULED AT 5 AM.

It seems like an unusual event but it seems to happen more often then you'd think. They just had Ioke.

[HurricaneBill]

I've always wondered what impacts remnant typhoons have on Alaska and the Russian Far East.

[Aslkahuna]

Shemya has had wind gusts well in excess of 100kt from typhoon remnants. For that matter so has the Pacific Northwest.

Columbus day 1962 right?

[Aslkahuna]

Yep. The remnants of STY Gay resulted in a decent coastal for CA in 1992 and we had gusts over 50 mph when that system came through here.

Didn't Gay's remnants make their way across the U.S. and eventually develop into the December Nor'easter of 1992?

I've heard Gay referred to as "the storm that wouldn't die".

Just some highlights of the Columbus Day Storm from a local Oregonian:

The Columbus Day Storm of 1962 was an extratropical wave cyclone that ranked among the most intense to strike the United States Pacific Northwest since at least 1948, and probably since the January 9, 1880, "Great Gale" and snowstorm. On a larger scale, the Columbus Day Storm of 1962 is a contender for the title of most powerful extratropical cyclone recorded in the U.S. in the 20th century; with respect to wind velocity, it is unmatched even by the much-touted March 1993 "Storm of the Century" and the "1991 Halloween Nor’easter" (aka "The Perfect Storm"). In the eastern United States, only hurricanes of Category 3 or higher have brought winds of the magnitude witnessed in Oregon on Columbus Day, October 12, 1962.

At Oregon's Cape Blanco, an anemometer that lost one of its cups registered wind gusts in excess of 145 mph (233 km/h); some reports put the peak velocity at 179 mph (288 km/h).

At the Mt. Hebo Air Force Station in Oregon's Coast Range, the anemometer pegged at its maximum 130 mph (209 km/h) for long periods—likely at the level of a Category 4 hurricane; damage to the radar domes suggested wind gusts to at least 170 mph (270 km/h). Dome tiles were thrown down the mountainside; the 200 lb (45 kg) chunks tore through entire trees.

At the Naselle Radar Station in the Willapa Hills of southwest Washington, a wind gust of 160 mph (257 km/h) was observed.

At Corvallis, Oregon, an inland location in the Willamette Valley, 1-minute average winds reached 69 mph (111 km/h), with a gust to 127 mph (204 km/h), before the anemometer was destroyed and the observation tower began flying apart, forcing the abandonment of the station.

Ninety miles (145 km) to the north, at Portland, Oregon's major metropolitan area, measured wind gusts reached 116 mph (187 km/h) at the Morrison Street Bridge.

Many anemometers, official and unofficial, within the heavily stricken area of northwestern Oregon and southwestern Washington were destroyed before winds attained maximum velocity.

For the Willamette Valley, the lowest peak gust officially measured was 86 mph at Eugene. This value, however, is higher than the maximum peak gust generated by any other Willamette Valley windstorm in the 1948–2003 period.

In the interior of western Washington, officially measured wind gusts included 78 mph at Olympia, 88 mph (138 km/h) at McChord Air Force Base, 100 mph (160 km/h) at Renton at 64 feet (20 m) and 98 mph (158 km/h) at Bellingham. In the city of Seattle, a peak fastest mile of 65 mph (105 km/h) was recorded; this suggests gusts of at least 80 mph (129 km/h). Damaging winds reached as far inland as Spokane.

Wind gusts of 58 mph (93 km/h), the National Weather Service minimum for "High Wind Criteria," or higher were reported from San Francisco, California, to Vancouver, British Columbia.

The low developed explosively off of Northern California when the degraded remains of typhoon Freda encountered a storm formation region that had spun up an intense cyclone the day before. The new (Columbus Day) low first moved northeastward, and then hooked straight north as it neared southwest Oregon. The storm then raced nearly northward at an average speed of 40 mph (64 km/h) or greater, with the center just 50 miles (80 km) off of the Pacific Coast. There was little central pressure change until the cyclone passed the latitude of Astoria, Oregon, at which time the low began to degrade. The center passed over Tatoosh Island, Washington, before landing on Vancouver Island, British Columbia, where it weakened rapidly.

The extratropical wave cyclone deepened to a minimum central pressure of at least 960 hPa (28.35 inHg), and perhaps as low as 958 hPa (28.30 inHg), which would be equivalent to a Category 3 hurricane on the Saffir-Simpson hurricane scale. All-time record-low land-based pressures (up to 1962) included 969.2 hPa (28.62 inHg) at Astoria, 970.5 hPa (28.66 inHg) at Hoquiam, Washington, and 971.9 hPa (28.70 inHg) at North Bend, Oregon. The Astoria and Hoquiam records were broken by a major storm on December 12, 1995 (966.1 hPa at Astoria)—this event, however, did not generate winds as intense as the Columbus Day storm of 1962.

At least 46 fatalities were attributed to this storm, more than for any other Pacific Northwest wind event. Injuries went into the hundreds. In terms of storm-related fatalities for the 20th century, only Oregon's Heppner flood of 1903 (200 deaths) and Washington's great avalanche of 1910 (96 deaths) caused more. For Pacific Northwest windstorms in the 20th century, the runner up was the infamous October 21, 1934, gale, which caused 22 fatalities, mostly in Washington.

The level of emergency caused by this storm exceeds that of any other Pacific Northwest event in memory. When queried, locals who experienced the storm nearly unanimously tell an account that is both interesting and frightening. The memory is vivid even four decades after the storm. For many, the response was to seek shelter immediately, move away from windows and go into interior rooms or basements. Few storms in the Pacific Northwest invoke such a strong response.

This happened to me just a few weeks ago. I was in Alaska from 9/4 to 9/14. We drove up to Denali on 9/7-9/9 and guess what? Remnants from a typhoon were in the Bering Sea which resulted in rainy weather while I was up there....MGC

[Aslkahuna]

Yes the December 1992 Nor'easter can be traced back to Gay and it's remnants. Some reasons why one should pay attention to the Pacific Tropical Cyclones (the EPAC ones have a habit of sending very juicy moisture surges into the US.

My avatar's a sat shot of STY Gay at peak intensity.

There are studies that indicate that Gay might have been more powerful than Tip, only that there was no recon measuring its central pressure.

What a storm!

I'm sure you meant to give Wikipedia some credit when you posted that.

[Floodo_Is_My_Hero]

Of course! I would never claim to be a writer by any means. When I saw the post about this storm it made me research it further. Apoligies for not giving credit in the post. We don't have weather like what people experience in Florida and the gulf very often and was just excited about sharing info. Thanks for keeping me honest Windrunner!

[kevin]

If anyone ever calls me on wikipedia plagerism I plan on responding that I wrote the article.

[Floodo_Is_My_Hero]

LOL! I should have thought of that...umm yeah...I wrote it.

[jhamps10]

actually the remants could go across the country along the jet-stream. sounds wierd that a west pacific typhoon could go across the entire country.

[Aslkahuna]

That's what we were talking about-the extratropical remnants of these storms and were pointing out some of the effects that some of them have had. In 1982, the remnants of CENPAC hurricane Iwa (until 1992 the strongest to hit HI) hit CA with winds gusting over 100 mph in the SFO Bay Area forcing closure of the GG Bridge and went on to wreak more havoc further east. Have to watch these things because the warm air they carry with them can be explosive when they tie in with a vigorous upper air system and can result in a system, which in the case of the 1962 event, can be stronger than the original tropical system wind wise. Beyond that, we were never claiming that we were talking about the typhoons themselves coming across.

Didn't the remnants of Super Typhoon Ginger in 1997 make it all the way across?
