Columbus Day Storm

The Columbus Day storm of 1962 (also known as the big blow of 1962, and originally in Canada as Typhoon Freda) was a Pacific Northwest windstorm that struck the West Coast of Canada and the Pacific Northwest coast of the United States on October 12, 1962. Typhoon Freda was the twenty-eighth tropical depression, the twenty-third tropical storm, and the eighteenth typhoon of the 1962 Pacific typhoon season. Freda originated from a tropical disturbance over the Northwest Pacific on September 28. On October 3, the system strengthened into a tropical storm and was given the name ''Freda'', before becoming a typhoon later that day, while moving northeastward. The storm quickly intensified, reaching its peak as a Category 3-equivalent typhoon on October 5, with maximum 1-minute sustained winds of and a minimum central pressure of . Freda maintained its intensity for another day, before beginning to gradually weaken, later on October 6. On October 9, Freda weakened into a tropical storm, before transitioning into an extratropical cyclone on the next day. On October 11, Freda turned eastward and accelerated across the North Pacific, before striking the Pacific Northwest on the next day. On October 13, the cyclone made landfall on Washington and Vancouver Island, and then curved northwestward. Afterward, the system moved into Canada and weakened, before being absorbed by another developing storm to the south on October 17.

The Columbus Day storm of 1962 is considered to be the benchmark of extratropical wind storms. The storm ranks among the most intense to strike the region since at least 1948, likely since the January 9, 1880 " Great Gale" and snowstorm. The storm is a contender for the title of the most powerful extratropical cyclone recorded in the U.S. in the 20th century; with respect to wind velocity, it is unmatched by the March 1993 " storm of the century" and the " 1991 Halloween Nor'easter" ("the perfect storm"). The system brought strong winds to the Pacific Northwest and southwest Canada, and was linked to 46 fatalities in the northwest and Northern California resulting from heavy rains and mudslides.

Meteorological history

On the morning of September 28, a tropical disturbance formed south of Eniwetok Atoll. After moving westward and making a large bend around the island, the new system slowly gained strength, and on the morning of October 3, the system became a tropical storm about from Wake Island, over the central Pacific Ocean. Now named ''Freda'', the system rapidly intensified as it proceeded northeastward over the open Pacific waters. On that afternoon, Freda intensified into a typhoon, with 1-minute sustained winds of . On October 4, the typhoon quickly intensified, reaching its peak of on the next day, with a minimum central pressure of , making the storm the equivalent of a Category 3 typhoon on the Saffir–Simpson scale. After stabilizing to the north, Freda maintained its strength through the Pacific, before beginning to weaken slowly on October 6. Making a turn to the northeast, Freda maintained typhoon-status winds for several more days, before weakening into a tropical storm on October 9, as it started experiencing the effects of cold air.

Moving northeastward at a steady rate of , the storm slowly underwent an extratropical transition, becoming extratropical operationally on the morning of October 10, still with winds of . The system became an extratropical cyclone as it moved into colder waters and interacted with the jet stream. However, post-season analysis concluded that the system continued weakening as it continued northeastward, crossing the 180th meridian later that afternoon, before completing the transition that evening.

The extratropical low redeveloped intensely off the coast of Northern California, due to favorable upper-level conditions, producing record rainfall across the San Francisco Bay Area that delayed some games in the 1962 World Series between the San Francisco Giants and the New York Yankees. The low moved northeastward, and then hooked straight north, as it neared southwest Oregon. The storm then raced nearly northward at an average speed of , with the center situated just off 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. On October 13, the center passed over Tatoosh Island, Washington, before making landfall on Vancouver Island, British Columbia, where it weakened rapidly. The cyclone then curved northwestward, before turning back eastward and moving into Canada. As the cyclone moved through Canada, another cyclone formed on its southern periphery, which absorbed the original cyclone by October 17.

The extratropical cyclone deepened to a minimum central pressure of at least , and perhaps as low as , a pressure which would be equivalent to a Category 3 hurricane on the Saffir–Simpson hurricane scale (SSHS). Since the system was an extratropical cyclone, its wind field was neither as compact nor as strong as a tropical cyclone, though its wind field was significantly larger. All-time record-low land-based pressures (up to 1962) included at Astoria, at Hoquiam, Washington, and at North Bend, Oregon. The Astoria and Hoquiam records were broken by a major storm on December 12, 1995 (which measured at Astoria); however, this event did not generate winds as intense as the Columbus Day Storm of 1962.

Wind speed highlights

The peak winds were felt as the storm passed close by on October 12. At Cape Blanco on the southern Oregon coast, an anemometer that lost one of its cups registered wind gusts in excess of ; some reports put the peak velocity at . The north Oregon coast Mt. Hebo radar station reported winds of .

At the Naselle Radar Station in the Willapa Hills of southwest Washington, a wind gust of was observed.

In Salem, Oregon, a wind gust of was recorded.

At Corvallis, Oregon, an inland location in the Willamette Valley, one-minute average winds reached , with a gust to , before the station was abandoned due to "power failure and instruments demolished". Observations at the weather station resumed the next day.

About to the north, at Portland, Oregon's major metropolitan area, measured wind gusts reached at the Morrison Street Bridge in downtown Portland.

A peak gust of was recorded at Pearson Field in Vancouver, Washington, around 10 miles north of downtown Portland.

Many anemometers, official and unofficial, within the heavily stricken area of northwestern Oregon and southwest Washington were damaged or destroyed before winds attained maximum velocity. For example, the wind gauge atop the downtown Portland studios of KGW radio and TV recorded two gusts of , just before flying debris knocked the gauge off-line shortly after 5 p.m.

For the Willamette Valley, the lowest peak gust officially recorded was at Eugene. This value, however, is higher than the maximum peak gust generated by any other Willamette Valley windstorm in the 1948–2010 period.

In the interior of western Washington, officially measured wind gusts included at Olympia, at McChord Air Force Base, at Renton at and at Bellingham. In the city of Seattle, a peak wind speed of was recorded; this suggests gusts of at least . Damaging winds reached as far inland as Spokane.

Wind gusts of , the National Weather Service minimum for "High Wind Criteria," or higher were reported from San Francisco, to Vancouver, British Columbia.

Impact

At least 46 fatalities were attributed to this storm, more than for any other Pacific Northwest weather event. Injuries went into the hundreds. In terms of natural disaster-related fatalities for the 20th century, only Oregon's Heppner Flood of 1903 (247 deaths), Washington's Wellington avalanche of 1910 (96 deaths), the Great Fire of 1910 (87 deaths), and Eruption of Mount St. Helens of 1980 (57 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.

In less than 12 hours, more than of timber was blown down in northern California, Oregon and Washington combined; some estimates put it at . This exceeded the annual timber harvest for Oregon and Washington at the time. This value is above any blowdown measured for East Coast storms, including hurricanes; even the often-cited 1938 New England hurricane, which toppled , falls short by nearly an order of magnitude.

Estimates put the dollar damage at approximately $230 million to $280 million for California, Oregon, and Washington combined. Those figures in 1962 US dollars translate to $1.8 to $2.2 billion in 2014 US dollars. Oregon's share exceeded $200 million in 1962 US dollars. This is comparable to land-falling hurricanes that occurred within the same time frame (for example, Audrey, Donna, and Carla from 1957 to 1961).

The Metropolitan Life Insurance Co. (now MetLife) named the Columbus Day Storm the nation's worst natural disaster of 1962.

California

In Central and Northern California, all-time record rains associated with the atmospheric river along the cold front caused major flooding and mudslides, particularly in the San Francisco Bay Area. Oakland set an all time calendar day record with of rain on the 13th, as did Sacramento with . More than of rainfall were recorded in the Bay area.

Heavy rain forced Game 6 of the 1962 World Series at San Francisco's Candlestick Park to be postponed from its originally scheduled date of October 11 to Monday, October 15.

Oregon

In the Willamette Valley, it is said the undamaged home was the exception. Livestock suffered greatly due to the barn failures: the animals were crushed under the weight of the collapsed structures, a story that was repeated many times throughout the afflicted region. At the north end of the Valley, two high voltage transmission towers were toppled.

Radio and TV broadcasting were affected in the Portland area. KGW-TV lost its tower at Skyline and replaced the temporary tower with a new one on January 28, 1963. KOIN radio lost one of two AM towers at Sylvan. KPOJ-AM/-FM lost much of its transmitting equipment, plus one of two towers was left partially standing at Mount Scott. KPOJ-FM was so badly damaged it wouldn't return to the air until February 9, 1963. KWJJ-AM lost one of its towers and a portion of its transmitter building at Smith Lake. KISN-AM also lost a tower at Smith Lake. Seven-month-old TV station KATU did not receive any damage at its Livingston Mountain site, north of Camas, Washington. However, KATU didn't have a generator and power was cut off. The heavy-duty design of the radio towers on Portland's West Hills today, with extensive and robust guy cables, is a direct result of the lessons learned from the 1962 catastrophe.

For northwest Oregon, the entire power distribution system had to be rebuilt from the ground up. Some locations did not have power restored for several weeks. This storm became a lasting memory for local power distributors. Indeed, a number of high wind related studies appeared in the years after the storm in an attempt to assess the return frequency of such potentially damaging winds.

The state capitol grounds at Salem, and the state's college campuses, resembled battlefields with heavy losses of trees.

The Campbell Hall tower at Oregon College of Education (now Western Oregon University) in Monmouth crashed to the ground, an event recorded by student photographer Wes Luchau in the most prominent picture-symbol of the storm.

East of Salem, the wind destroyed a historic barn that served as a clandestine meeting place by pro-slavery Democratic members of the state Legislature in 1860.

The Oregon State Beavers–Washington Huskies college football game went on as scheduled Saturday, October 13 in Portland, in a heavily damaged Multnomah Stadium. Much of the roof was damaged and seats damaged by falling debris were replaced by portable chairs. Crews cleared debris from the grandstand and playing field right up to kickoff. Most of the electricity, including the scoreboard and clock, was still out and players dressed by candlelight in the locker rooms. The Huskies came from behind to beat the Beavers 14–13, despite a strong performance by quarterback Terry Baker, who would win the Heisman Trophy later that year.

Washington

The storm caused 9 fatalities in Washington, some from falling trees or downed power lines. The Willapa Hills and southern portion of the Olympic Peninsula incurred the worst damage in the state, losing entire stands of trees. The Department of Commerce estimated damage in six western counties at more than $20 million.

British Columbia

The storm weakened as it traveled north into British Columbia, with peak gusts measured at . Five people in British Columbia were killed in the storm, and the area suffered $80 million in damages. Stanley Park lost 3,000 trees. A Victoria resident described it as "Just general devastation everywhere you went. There were trees breaking off and flying across the roads. Wind was just blowing the rain horizontal and trees were weaving all over the place. You didn't know if you were going to get hit or not." At Victoria airport, a Martin Mars waterbomber ("Caroline Mars") was hurled and irreparably damaged.
