Columbus Day Storm of 1962

The Columbus Day Storm of 1962 (also known as the Big Blow,[2] and originally 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. It is considered 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 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.

Synoptic history

Storm2
Storm trajectory compared to two other important storms hitting the Pacific Northwest in 1981 and 1995

Typhoon Freda formed 500 miles (800 km) from Wake Island in the central Pacific Ocean.[3] The system became an extratropical cyclone as it moved into colder waters and interacted with the jet stream. The low redeveloped intensely off Northern California due to favorable upper level conditions, producing record rainfalls in 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 40 miles per hour (64 km/h), with the center just 50 miles (80 km) 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. The center passed over Tatoosh Island, Washington, before landing on Vancouver Island, British Columbia, where it weakened rapidly. As the cyclone moved through Canada, another cyclone formed on its southern periphery, which merged with this cyclone by October 17.[4]

The extratropical wave cyclone deepened to a minimum central pressure of at least 960 hPa (28 inHg), and perhaps as low as 958 hPa (28.3 inHg), a pressure which would be equivalent to a Category 3 hurricane on the Saffir-Simpson hurricane scale. Since it was an extratropical cyclone, its wind field was neither as compact nor as strong as a tropical cyclone. 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 (which measured 966.1 hPa (28.53 inHg) at Astoria); this event, however, did not generate winds as intense as the Columbus Day Storm of 1962.

Wind speed highlights

ColumbusDayStormPeakGustMap
Most of these peak gusts were taken at official stations[5]

The peak winds were felt as the storm passed close by on October 12. At Oregon's Cape Blanco, an anemometer that lost one of its cups registered wind gusts in excess of 145 miles per hour (233 km/h); some reports put the peak velocity at 179 miles per hour (288 km/h). The north Oregon coast Mt. Hebo radar station reported winds of 170 mph.[6]

At the Naselle Radar Station in the Willapa Hills of southwest Washington, a wind gust of 160 miles per hour (260 km/h) was observed.[5]

In Salem, Oregon, a wind gust of 90 miles per hour (140 km/h) was observed.[5]

At Corvallis, Oregon, an inland location in the Willamette Valley, one-minute average winds reached 69 miles per hour (111 km/h), with a gust to 127 miles per hour (204 km/h), before the station was abandoned due to "power failure and instruments demolished". Observations at the weather station resumed the next day.[5]

About 80 miles (130 km) to the north, at Portland, Oregon's major metropolitan area, measured wind gusts reached 116 miles per hour (187 km/h) at the Morrison Street Bridge in downtown Portland.

A peak gust of 92 miles per hour (148 km/h) was observed in Vancouver, Washington at Pearson Field, around 9 miles to the 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 93 miles per hour (150 km/h), just before flying debris knocked the gauge off-line[7] shortly after 5 p.m.

For the Willamette Valley, the lowest peak gust officially measured was 86 miles per hour (138 km/h) 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 78 miles per hour (126 km/h) at Olympia, 88 miles per hour (142 km/h) at McChord Air Force Base, 100 miles per hour (160 km/h) at Renton at 64 feet (20 m) and 98 miles per hour (158 km/h) at Bellingham. In the city of Seattle, a peak wind speed of 65 miles per hour (105 km/h) was recorded; this suggests gusts of at least 80 miles per hour (130 km/h). Damaging winds reached as far inland as Spokane.

Wind gusts of 58 miles per hour (93 km/h), 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.[8] 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 11 billion board feet (26,000,000 m3) of timber was blown down in northern California, Oregon and Washington combined; some estimates put it at 15 billion board feet (35,000,000 m3). 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 2.65 billion board feet (6,300,000 m3), 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 dollars translate to $1.8 Billion to $2.2 Billion in 2014 Dollars. Oregon's share exceeded $200 million in 1962 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).[9]

The Metropolitan Life Insurance Co. (now MetLife) named the Columbus Day Storm the nation's worst natural disaster of 1962.[10]

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 4.52 inches (115 mm) of rain on the 13th, as did Sacramento with 3.77 inches (96 mm). More than 7 inches (180 mm) of rainfall were recorded in the Bay area.[11]

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

Columbus Day Storm 1962
Damage in Newberg, 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 500-foot (150 m) 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, 6 miles (9.7 km) 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.[8] 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,[12] 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 BeaversWashington 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.[13] Crews cleared debris from the grandstand and playing field right up to kickoff.[13] Most of the electricity, including the scoreboard and clock, was still out and players dressed by candlelight in the locker rooms.[14] 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.[14][15]

Aerocar

Aerocar International's Aerocar (often called the Taylor Aerocar) was an American roadable aircraft, designed and built by Moulton Taylor in Longview, Washington, in 1949. Although six examples were built, the Aerocar never entered production.

Barber Block

The Barber Block is a building complex located at the corner of Southeast Grand and Washington Streets in Portland, Oregon, listed on the National Register of Historic Places (NRHP). It was built in 1890 and listed on the NRHP in 1977. It is also located within the East Portland Grand Avenue Historic District.

Among the building's occupants in the 1920s was a nickelodeon theater. After the Columbus Day Storm of 1962 caused significant damage to the building's roof, its owners considering demolishing it, but decided against doing so. The ground floor spaces have been used by various types of businesses over the decades, including a furniture store, a restaurant and a bank, while the second and third floors have always been residential, mostly as apartments but for a time as a single-room occupancy residential hotel.The building underwent a renovation in the late 1970s and another in the 2000s.

Black Butte (Siskiyou County, California)

Black Butte is a cluster of overlapping dacite lava domes in a butte,

a parasitic cone of Mount Shasta. It is located directly adjacent to Interstate 5 at milepost 742 between the city of Mount Shasta and Weed, California. The highway crosses a 3,912 ft (1,192 m) pass, Black Butte Summit, at the western base of the lava domes. The lava domes were extruded at the foot of the cone of Shastina following the period of its major eruptions about 9,000–10,000 years ago.A United States Forest Service fire lookout tower was built on the summit in the early 1930s, but destroyed during the Columbus Day Storm of 1962. A new lookout was built in 1963 and operated until 1973. The building was moved by helicopter to a new location in 1975 and only the concrete foundation remains today. A 2.5-mile-long (4.0 km) trail leads to the summit from a trailhead accessible by gravel roads off the Everitt Memorial Highway.

The summit boasts an outstanding view of the southwest side of Shasta and Shastina, and on clear days Mount McLoughlin is easily visible 70 miles (113 km) to the north in Oregon.

Bonnie Bronson

Bonnie Bronson (1940–1990) was an American painter and sculptor and one of Portland, Oregon's most prominent artists during the 1970s–1980s. Randal Davis said that her work showed "an abiding love for the sheer beauty of materials and a fascination with unusual structures and systems."Bronson was born in Portland in 1940, and attended the University of Kansas, the University of Oregon, and the Portland Art Museum School. She married sculptor Lee Kelly in 1961. After their Portland home and studio were heavily damaged in the Columbus Day Storm of 1962, they purchased a former dairy farm outside of Oregon City, where they spent the rest of their lives. They had two children, Kassandra and Jason. In 1990, Bronson died at age 50 in a mountaineering accident on Mazama Glacier on Mt. Adams, Washington. An award in her name, the Bonnie Bronson Fellowship, is presented to one Pacific Northwest artist each year.

Braer Storm of January 1993

The Braer Storm of January 1993 was the most intense extratropical cyclone ever recorded over the northern Atlantic Ocean. Developing as a weak frontal wave on 8 January 1993, the system moved rapidly northeast. The combination of the absorption of a second low-pressure area to its southeast, a stronger than normal sea surface temperature differential along its path, and the presence of a strong jet stream aloft led to a rapid strengthening of the storm, with its central pressure falling to an estimated 914 hPa (914 mb; 27.0 inHg) on 10 January. Its strength was well predicted by forecasters in the United Kingdom, and warnings were issued before the low initially developed.

Gale-force winds covered the far northern Atlantic between Western Europe and Atlantic Canada, due to the intensity of this storm, with hurricane-force winds confined near its center of circulation. After reaching its peak intensity, the system weakened as it moved into the far northeast Atlantic, dissipating by 17 January. This storm caused severe blizzards across much of Scotland. It also led to the final breakup of the oil tanker MV Braer, from which the storm derived its name; it had been stranded in rocks off the Shetland Islands by a previous storm nearly a week beforehand.

Extratropical cyclone

Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to heavy gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone.

Great Gale of 1880

The Great Gale of 1880 was an extremely intense extratropical cyclone (possibly deeper than 955 millibars (mb) or 28.20") that impacted the Northwest United States on January 9, 1880.

Hoyt Arboretum

The Hoyt Arboretum is located atop a ridge in the west hills of Portland, Oregon, United States. The arboretum is located two miles (3 km) west of downtown Portland within Washington Park, and close to the Oregon Zoo, and the International Rose Test Garden. The Arboretum is open to the public and accessible at several points from Washington Park or from the Wildwood Trail from Forest Park.

Humbug Mountain

Humbug Mountain lies on the southern coast of the U.S. state of Oregon. It is located about 6 miles (10 km) south of Port Orford, and 21 miles (34 km) north of Gold Beach, on the Pacific Ocean. The mountain is completely within Humbug Mountain State Park, and U.S. Route 101 passes by its northern base. It is one of the highest mountains in Oregon to rise directly from the ocean.

Its slopes feature an old-growth temperate rainforest.

Two trails run from the state park campground to the mountain's summit, one 1.5 miles (2.4 km) long, the other 2 miles (3.2 km) long. Both are part of the much longer Oregon Coast Trail. The area is popular with hikers, campers, cyclists, and whale watchers.

January 2012 Pacific Northwest snowstorm

The January 2012 Pacific Northwest snowstorm was a large extratropical cyclone that brought record snowfall to the Pacific Northwest in January 2012. The storm produced very large snowfall totals, reaching up to 50 inches (1,300 mm) in Oregon. A 110 mph (180 km/h) wind gust was reported at Otter Rock, Oregon. A mother and child were killed in Oregon after the car they were in slid into a creek, while a man was killed in the Seattle area. About 200,000 homes were without power in the Greater Seattle area after the storm.

KSTW

KSTW, virtual and VHF digital channel 11, is a CW owned-and-operated station television station serving Seattle, Washington, United States that is licensed to Tacoma. The station is owned by the CBS Television Stations subsidiary of CBS Corporation. KSTW's studios are located on Dexter Avenue in Seattle's Westlake neighborhood, and its transmitter is located on Capitol Hill east of downtown.

KSTW is available on cable television to Canadian customers in southwestern British Columbia on numerous cable providers such as Shaw Cable and TELUS Optik TV in Victoria, Vancouver, Penticton and Kelowna.

List of Canada hurricanes

A Canadian hurricane is a tropical cyclone originating in the Atlantic or Pacific Ocean affecting the country of Canada. Canada is usually only hit with weak storms, due to the generally cool waters immediately offshore. However, some hurricanes can strike the area full force as the warm Gulf Stream extends fairly close to Atlantic Canada. Due to the cool waters for a great distance from the Pacific coast of Canada, there has never been a storm of any intensity to directly affect the Pacific coast. On occasion tropical systems can transition into, or be absorbed by, non-tropical systems that strongly affect western Canada, most notably by the remnants of Typhoon Freda that were absorbed by the Columbus Day Storm of 1962.

According to the Canadian Hurricane Centre, Hurricane Ella of 1978 is the strongest tropical cyclone in Canadian waters, passing approximately 335 miles (540 km) south of Halifax, Nova Scotia as a Category 4 hurricane. Despite this however, Ella did not make landfall. The strongest hurricane to make landfall in Canada was Hurricane Ginny of 1963, which had winds of 110 mph (175 km/h), making it a strong Category 2 hurricane at the time of its landfall near Yarmouth, Nova Scotia.Sometimes, a hurricane will make landfall in the United States and continue northward to dissipate over (or partially over) Canada. Only a handful of storms that have taken this path were devastating in Canada. Two examples of this include the 1900 Galveston hurricane and Hurricane Hazel in 1954.

Many extratropical remnants of tropical cyclones have entered Canada. They are not included in this list unless they were particularly notable. Storms that have entered Canada from the U.S. after landfall are omitted from these lists, exceptions being devastating, or notable cyclones.

This article includes hurricanes that affected Newfoundland and Labrador prior to its entry into Canada in 1949, and hurricanes that affected any Canadian provinces before confederation in 1867.

November 2011 Bering Sea cyclone

The November 2011 Bering Sea cyclone was one of the most powerful extratropical cyclones to affect Alaska on record. On November 8, the National Weather Service (NWS) began issuing severe weather warnings, saying that this was a near-record (or record) storm in the Bering Sea. It rapidly deepened from 973 mb (28.7 inHg) to 948 mb (28.0 inHg) in just 24 hours before bottoming out at 943 mbar (hPa; 27.85 inHg), roughly comparable to a Category 3 or 4 hurricane. The storm had been deemed life-threatening by many people. The storm had a forward speed of at least 60 mph (97 km/h) before it had reached Alaska. The storm began affecting Alaska in the late hours of November 8, 2011. The highest gust recorded was 93 mph (150 km/h) on Little Diomede Island. One person has been reported missing after being swept into the Bering Sea.

November 2014 Bering Sea cyclone

The November 2014 Bering Sea cyclone (also referred to as Post-Tropical Cyclone Nuri by the U.S. government) was the most intense extratropical cyclone (also a bomb cyclone) ever recorded in the Bering Sea, which formed from a new storm developing out of the low-level circulation that separated from Typhoon Nuri, which soon absorbed the latter. The cyclone brought gale-force winds to the western Aleutian Islands and produced even higher gusts in other locations, including a 97 miles per hour (156 km/h) gust in Shemya, Alaska. The storm coincidentally occurred three years after another historic extratropical cyclone impacted an area slightly further to the east.

October 2009 North American storm complex

The October 2009 North American storm complex was a powerful extratropical cyclone that was associated with the remnants of Typhoon Melor, which brought extreme amounts of rainfall to California. The system started out as a weak area of low pressure (an Aleutian Low), that formed in the northern Gulf of Alaska on October 7. Late on October 11, the system quickly absorbed Melor's remnant moisture, which resulted in the system strengthening significantly offshore, before moving southeastward to impact the West Coast of the United States, beginning very early on October 13. Around the same time, an atmospheric river opened up (the Pineapple Express), channeling large amounts of moisture into the storm, resulting in heavy rainfall across California and other parts of the Western United States.

Shimanek Bridge

The Shimanek Bridge is a covered bridge near Scio in Linn County in the U.S. state of Oregon. It was added to the National Register of Historic Places as Thomas Creek – Shimanek Covered Bridge in 1987.The bridge, 130 feet (40 m) long, was completed in 1966. Replacing a similar structure severely damaged by the Columbus Day Storm of 1962, it is the fifth bridge at this location. The fourth bridge had been built in 1927, and the first is thought to have dated to 1861.Carrying Richardson Gap Road, the bridge crosses Thomas Creek about 2 miles (3 km) east of Scio. It is the longest covered bridge in Linn County and the newest. A county crew renovated the structure in 2002, repairing damage caused by a flood in 1996.In November 2015, the bridge was closed for repairs after an inspection revealed "serious decay". Temporary repairs were expected to take weeks. More substantial repairs may not occur for up to two years, depending on funding.

Superstorm

A superstorm is a large, destructive storm without another distinct meteorological classification, such as hurricane or blizzard. As the term is of recent coinage and lacks a formal definition, there is some debate as to its usefulness.

The Circuit Rider

The Circuit Rider is a bronze sculpture by Alexander Phimister Proctor, located in Capitol Park, east of the Oregon State Capitol in Salem, Oregon, in the United States.

Waite Fountain

Waite Fountain is an outdoor fountain installed on the Oregon State Capitol grounds, in Salem, Oregon, United States. The original cylindrical fountain was erected in 1912. It was damaged during the Columbus Day Storm of 1962, and has been replaced by a low, modern pool fountain.
