The Tacoma Narrows Bridge is a pair of twin suspension bridges that span the Tacoma Narrows strait of Puget Sound in Pierce County, Washington. The bridges connect the city of Tacoma with the Kitsap Peninsula and carry State Route 16 over the strait. Historically, the name "Tacoma Narrows Bridge" has applied to the original bridge, nicknamed "Galloping Gertie", which opened in July 1940 but collapsed possibly because of aeroelastic flutter four months later, as well as to the successor of that bridge, which opened in 1950 and still stands today as the westbound lanes of the present-day two-bridge complex.
An ice storm, also known as a glaze event or a silver storm, is a type of winter storm characterized by freezing rain. The U.S. National Weather Service defines an ice storm as a storm which results in the accumulation of at least 0.25-inch (6.4 mm) of ice on exposed surfaces. They are generally not violent storms but instead are commonly perceived as gentle rains occurring at temperatures just below freezing.
Hurricane Isabel was the strongest Atlantic hurricane since Mitch, and the deadliest, costliest, and most intense hurricane in the 2003 Atlantic hurricane season. Hurricane Isabel was also the strongest hurricane in the open waters of the Atlantic, both by wind speed and central pressure, before being surpassed by hurricanes Irma and Dorian in 2017 and 2019, respectively. The ninth named storm, fifth hurricane, and second major hurricane of the season, Isabel formed near the Cape Verde Islands from a tropical wave on September 6, in the tropical Atlantic Ocean. It moved northwestward, and within an environment of light wind shear and warm waters, it steadily strengthened to reach peak winds of 165 mph (266 km/h) on September 11. After fluctuating in intensity for four days, during which it displayed annular characteristics, Isabel gradually weakened and made landfall on the Outer Banks of North Carolina, with winds of 105 mph (169 km/h) on September 18. Isabel quickly weakened over land and became extratropical over western Pennsylvania on the next day. On September 20, the extratropical remnants of Isabel were absorbed into another system over Eastern Canada.
The Columbus Day storm of 1962 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 115 mph (185 km/h) and a minimum central pressure of 948 millibars (28.0 inHg). 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 Great Gale of 1880 was an intense extratropical cyclone that impacted the Northwest United States on January 9, 1880.
The greatest snowstorm, and perhaps overall worst storm in SW Washington and NW Oregon history, was that dubbed the ‘Storm King’ event of January 9, 1880.... Little data is available for the so-called ‘Storm King’ of January 1880, but it appears the storm center came ashore just south of Astoria, Oregon, on January 9th when a barometric pressure of 28.45” was registered in the town. Portland bottomed out at 28.56.
Hurricane Ernesto was the costliest tropical cyclone of the 2006 Atlantic hurricane season. The sixth tropical storm and first hurricane of the season, Ernesto developed from a tropical wave on August 24 in the eastern Caribbean Sea. Ernesto first affected the northern Caribbean, reaching minimal hurricane status near Haiti before weakening and moving across eastern Cuba as a tropical storm. Despite initial predictions for it to track through the eastern Gulf of Mexico as a major hurricane, Ernesto moved across eastern Florida as a weak tropical storm. After turning to the northeast, it re-intensified and made landfall on August 31 on the North Carolina coast just below hurricane status. Late the next day, Ernesto became extratropical after entering southern Virginia. The remnants spread moisture across the northeastern United States before dissipating over eastern Canada on September 4.
The 1972 Portland–Vancouver tornadoes were caused by an unusually intense squall line with embedded strong tornadoes that struck Oregon and Washington on Wednesday, April 5, 1972. Of the four tornadoes, the most catastrophic event was a deadly F3 tornado that struck Portland, Oregon, and Vancouver, Washington, the first F3 tornado to strike Oregon since June 3, 1894. It tracked 8.7 miles (14.0 km) across the heavily populated Portland–Vancouver metropolitan area, causing heavy damage, killing six people, and injuring 300 while causing $25.25 million in damage. It was tied as the deadliest tornado in the United States in 1972 and remains the deadliest tornado in the history of the Pacific Northwest. In all, the outbreak killed six, injured 301, and caused $25.55 million in damage.
The Early Winter 2006 North American storm complex was a severe winter storm that occurred on November 26, 2006, and continued into December 1. It affected much of North America in some form, producing various kinds of severe weather including a major ice storm, blizzard conditions, high winds, extreme cold, a serial derecho and some tornadoes.
In Maryland and Washington, D.C., the effects of Hurricane Isabel were among the most damaging from a tropical cyclone in the respective metropolitan area. Hurricane Isabel formed from a tropical wave on September 6, 2003, in the tropical Atlantic Ocean. It moved northwestward, and within an environment of light wind shear and warm waters, it steadily strengthened to reach peak winds of 165 miles per hour (266 km/h) on September 11. After fluctuating in intensity for four days, Isabel gradually weakened and made landfall on the Outer Banks of North Carolina with winds of 105 miles per hour (169 km/h) on September 18. It quickly weakened over land and became extratropical over western Pennsylvania the next day.
The effects of Hurricane Isabel in Virginia proved to be the costliest disaster in the history of Virginia. Hurricane Isabel formed from a tropical wave on September 6, 2003, in the tropical Atlantic Ocean. It moved northwestward, and within an environment of light wind shear and warm waters it steadily strengthened to reach peak winds of 265 km/h (165 mph) on September 11. After fluctuating in intensity for four days, Isabel gradually weakened and made landfall on the Outer Banks of North Carolina with winds of 165 km/h (103 mph) on September 18. It quickly weakened over land as it passed through central Virginia, and Isabel became extratropical over western Pennsylvania on September 19.
The Great Coastal Storm of 2007 was a series of three powerful Pacific storms that affected the U.S. states of Oregon and Washington and the Canadian province of British Columbia between December 1, 2007 and December 4, 2007.
The January 2008 North American storm complex was a powerful Pacific extratropical cyclone that affected a large portion of North America, primarily stretching from western British Columbia to near the Tijuana, Mexico area, starting on January 3, 2008. The system was responsible for flooding rains across many areas in California along with very strong winds locally exceeding hurricane force strength as well as heavy mountain snows across the Cascade and Sierra Nevada mountain chains as well as those in Idaho, Utah and Colorado. The storms were responsible for the death of at least 12 people across three states, and extensive damage to utility services as well, as damage to some other structures. The storm was also responsible for most of the January 2008 tornado outbreak from January 7–8.
Cyclone Klaus was a European windstorm or cyclone that made landfall over large parts of central and southern France, Spain and parts of Italy in January 2009. The storm was the most damaging since Lothar and Martin in December 1999. The storm caused widespread damage across France and Spain, especially in northern Spain.
A high wind storm which began early in the morning of December 1, 2011, reached wind speeds as high as 102 miles per hour (164 km/h) in Centerville, Utah, United States and surrounding cities. Fruit Heights, a neighborhood just 15 miles from the Utah State Capitol, saw gusts of up to 146 mph (235 km/h) during the event. Damage was reported throughout Davis County, and extending into Weber and Salt Lake counties, ranging from Ogden down to Salt Lake City. That morning Mayor Ron Russell of Centerville declared a local state of emergency. Due to the extensive damage, Davis County declared a state of emergency later that evening. The windstorm extended throughout the Western United States, with power outages and structural damage also reported in California and Nevada.
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.
Pacific Northwest windstorms, sometimes colloquially known as Big Blows, are extratropical cyclones which form in the Pacific basin, and affect land areas in the Pacific Northwest of the United States and British Columbia, Canada. They form as cyclonic windstorms associated with areas of low atmospheric pressure that track across the North Pacific Ocean towards western North America. Deep low pressure areas are relatively common over the North Pacific. They are most common in the winter months. On average, the month when most windstorms form is November or December.
The St. Jude storm, also known as Cyclone Christian, and other names, was a severe hurricane-force European windstorm that hit Northwestern Europe on 27 and 28 October 2013 causing at least 17 deaths. The highest windspeed was in Denmark, where a gust of 194.4 km/h (120.8 mph) was recorded in the south of the country on the afternoon of 28 October, the strongest wind recorded in the country's history.
Electricity in the Puget Sound region is a significant factor in people's lives, an enabler for the modern economy, and has a unique relationship with the region's environment.
Several storms struck the coast of British Columbia in December 2018, some causing damage, and one death.
The Great Olympic Blowdown, also called the Big Blow, was a compact, intense windstorm that struck the coast of Washington on January 29, 1921. The storm is remembered for the massive number of trees destroyed. At the time, it was the greatest loss of timber in the country, according to the Forest Service. In the twentieth century, only the Columbus Day Storm of 1962 was stronger.
