On April 5, 2023, the 2023 Canadian ice storm devastated Quebec and Ontario, knocked out electricity for more than a million people, resulted in fatalities, and severely damaged property and infrastructure. [1]
The two most populous provinces in Canada, Ontario and Quebec, were most severely impacted by the natural catastrophe, with the worst power outage in Quebec since the 1998 ice storm brought on by toppled power lines and blocked roadways. Two people died as a consequence of the storm's effects: one was crushed by a falling limb in Quebec and another was killed by a falling tree in Ontario. While encouraging locals to stay away from downed power lines and to avoid going in forested areas where trees loaded with ice may topple, emergency workers worked to clean roadways and reconnect power lines. [2]
The weather warnings were cancelled and the situation was under control, according to the authorities, but they nevertheless recommended care because it would take many weeks to repair the damage brought on by the ice storm. François Legault, the premier of Quebec, emphasized the dangers of extreme weather conditions and the rising probability that they may occur as a result of climate change. [3]
Canadian Prime Minister Justin Trudeau, who was present in Montreal at the time, described the storm as a trying period for residents of Montreal and others who had been impacted by the tragedy throughout the province. Long-lasting cleanup and restoration operations are needed to bring the afflicted communities back to normality after the ice storm. [4]
A winter storm is an event in which wind coincides with varieties of precipitation that only occur at freezing temperatures, such as snow, mixed snow and rain, or freezing rain. In temperate continental climates, these storms are not necessarily restricted to the winter season, but may occur in the late autumn and early spring as well. A snowstorm with strong winds and other conditions meeting certain criteria is called a blizzard.
The North American Ice Storm of 1998 was a massive combination of five smaller successive ice storms in January 1998 that struck a relatively narrow swath of land from eastern Ontario to southern Quebec, New Brunswick and Nova Scotia in Canada, and bordering areas from northern New York to central Maine in the United States. It caused massive damage to trees and electrical infrastructure throughout the area, leading to widespread long-term power outages. Millions were left in the dark for periods varying from days to several weeks, and in some instances, months. It led to 34 fatalities, a shutdown of activities in large cities like Montreal and Ottawa, and an unprecedented effort in reconstruction of the power grid. The ice storm led to the largest deployment of Canadian military personnel since the Korean War, with over 16,000 Canadian Forces personnel deployed, 12,000 in Quebec and 4,000 in Ontario at the height of the crisis.
Hurricane Carol was among the worst tropical cyclones on record to affect the states of Connecticut and Rhode Island in the United States. It developed from a tropical wave near the Bahamas on August 25, 1954, and slowly strengthened as it moved northwestward. On August 27, Carol intensified to reach winds of 105 mph (169 km/h), but weakened as its motion turned to a northwest drift. A strong trough of low pressure turned the hurricane northeastward, and Carol later intensified into a major hurricane. While paralleling the Mid-Atlantic and Southeastern United States, the storm produced strong winds and rough seas that caused minor coastal flooding and slight damage to houses in North Carolina, Virginia, Washington, D.C., Delaware, and New Jersey. The well-organized hurricane accelerated north-northeastward and made landfall on eastern Long Island, New York, and then over eastern Connecticut on August 31 with sustained winds estimated at 110-mph and a barometric pressure near 956 mb. Carol later transitioned into an extratropical cyclone over New Hampshire, on August 31, 1954.
The December 2005 North American ice storm was a damaging winter storm that produced extensive ice damage in a large portion of the Southern United States from December 14–16, 2005, while extensive snowfall was reported across portions of the Canadian provinces of Ontario and Quebec. The ice storm led to enormous and widespread power outages, and at least 7 deaths.
The heat wave of 2006 derecho series were a set of derechos — severe winds with powerful thunderstorms — that occurred on July 17–21, 2006. The first storms hit a wide swath of north-central and northeastern North America that stretched from the Upper Midwest through much of Ontario and into the northeastern United States. Another round struck the middle Mississippi River Valley, including two derechos that hit St. Louis, Missouri. The storms left more than three million people without power, some more than once and some for weeks.
The October 2006 Buffalo storm was an unusual early-season lake effect snow storm that hit the Buffalo, New York area and other surrounding areas of the United States and Canada, from the afternoon of Thursday, October 12 through the morning of Friday, October 13, 2006. It was called Lake Storm Aphid by the National Weather Service office in Buffalo, in accordance with their naming scheme for lake-effect snowstorms for that year, which related to insects, though locals never used that terminology and have simply referred to it as the October Surprise or the October Storm or Arborgeddon.
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.
The January 2007 North American ice storm was a severe ice storm that affected a large swath of North America from the Rio Grande Valley to New England and southeastern Canada, starting on January 11 and lasting until January 16. It was followed by a second wave in the Southern United States from Texas to the Carolinas from January 16 through January 18, and a third one that hit the southern Plains and mid-Atlantic states as well as Newfoundland and Labrador from January 19 to January 24. It resulted in at least 74 deaths across 12 U.S. states and three Canadian provinces, and caused hundreds of thousands of residents across the U.S. and Canada to lose electric power.
The February 2007 North American blizzard was a massive winter storm that affected most of the eastern half of North America, starting on February 12, 2007 and peaking on Valentine's Day, February 14. The storm produced heavy snowfalls across the midwestern United States from Nebraska to Ohio and produced similar conditions across parts of the northeastern United States, and into Canada in Ontario, Quebec and New Brunswick. Significant sleet and freezing rain fell across the southern Ohio Valley and affected portions of the east coast of the United States, including the cities of Boston, Baltimore, Washington, D.C., New York City and Philadelphia.
The Mid-December 2007 North American winter storms were a series of two winter storms that affected much of central and eastern North America, from December 8 to December 18, 2007. The systems affected areas from Oklahoma to Newfoundland and Labrador with freezing rain, thunderstorms, sleet, snow, damaging winds, and blizzard-like conditions in various areas. The first two storms produced copious amounts of ice across the Midwestern United States and Great Plains from December 8 to December 11, knocking out power to approximately 1.5 million customers from Oklahoma north to Iowa. The second storm moved northeast, producing heavy snow across New York and New England. A third storm was responsible for a major winter storm from Kansas to the Canadian Maritimes, bringing locally record-breaking snowfalls to Ontario, an icestorm across the Appalachians, and thunderstorms and tornadoes to the Southeastern United States.
The effects of Hurricane Ike in inland North America, in September 2008, were unusually intense and included widespread damage across all or parts of eleven states - Arkansas, Illinois, Indiana, Kentucky, Michigan, Missouri, New York, Ohio, Pennsylvania, Tennessee and West Virginia, and into parts of Ontario as Ike, which had rapidly become an extratropical cyclone, was enhanced by an adjacent frontal boundary and produced widespread winds with gusts to hurricane-force in several areas. In addition, significant flooding which was already underway due to heavy rain from the front to the north was worsened by rainfall brought on by Ike in parts of Missouri, Illinois and Indiana to the west of the center.
Global storm activity of 2008 profiles the major worldwide storms, including blizzards, ice storms, and other winter events, from January 1, 2008 to December 31, 2008. A winter storm is an event in which the dominant varieties of precipitation are forms that only occur at cold temperatures, such as snow or sleet, or a rainstorm where ground temperatures are cold enough to allow ice to form. It may be marked by strong wind, thunder and lightning, heavy precipitation, such as ice, or wind transporting some substance through the atmosphere. Major dust storms, Hurricanes, cyclones, tornados, gales, flooding and rainstorms are also caused by such phenomena to a lesser or greater existent.
Global weather activity of 2007 profiles the major worldwide weather events, including blizzards, ice storms, tornadoes, tropical cyclones, and other weather events, from January 1, 2007, to December 31, 2007. Winter storms are events in which the dominant varieties of precipitation are forms that only occur at cold temperatures, such as snow or sleet, or a rainstorm where ground temperatures are cold enough to allow ice to form. It may be marked by strong wind, thunder and lightning, heavy precipitation, such as ice, or wind transporting some substance through the atmosphere. Other major non winter events such as large dust storms, Hurricanes, cyclones, tornados, gales, flooding and rainstorms are also caused by such phenomena to a lesser or greater existent.
The December 1969 nor'easter was a strong winter storm that mainly affected the Northeastern United States and southern Quebec between December 25 and December 28, 1969. The multi-faceted storm system included a tornado outbreak, record snow accumulations, a damaging ice storm, and flooding rains.
The December 2013 North American storm complex was a significant storm complex that included many different types of severe weather, including a winter storm, a crippling ice storm and a tornado outbreak that impacted the central and eastern portions of Canada, parts of the Central Great Plains, the Southern United States, and the northeastern United States from 20 to 23 December 2013. Formed in the South Central United States, the storm headed across the Great Plains towards Canada into Atlantic Canada and northeastern United States where the storm dissipated on 23 December 2013. The storm produced freezing rain and snow to the affected areas which caused massive damage to electric power transmission and trees. The storm resulted in 29 deaths, loss of power to over a million residents and over $200 million in damages. The storm produced similar conditions to the ice storm of 1998 which affected similar areas.
The 2016–17 North American winter was quite warm across North America in general, due in part to a weak La Niña that was expected to influence weather conditions across the continent. Several notable events occurred during the season, including a potent winter storm that affected the East Coast of the United States in early January, the second-largest winter tornado outbreak on record later that month, and an unusually warm February. In addition, towards the end of the season, a large cyclonic storm system that caused a large tornado outbreak, flooding, and a potent blizzard occurred in the Heartland of the country. However, the most notable event of the winter was a powerful blizzard that impacted the Northeast and New England in mid-March, towards the end of the season.
The 2020–21 North American winter was the most significant winter season to affect North America in several years, and the costliest on record, with a damage total of at least $33.35 billion. The season featured 6 storms ranking on the Regional Snowfall Index scale, with 4 storms ranking as at least a Category 3. Most of the winter's damage and fatalities occurred due to a historic and major cold wave in mid-February. Several other significant events occurred, including a crippling early-season ice storm in the Southern Plains, a powerful nor'easter in mid-December, another major nor'easter in early February, two major and widespread winter storms in mid-February, and a major blizzard in the Rocky Mountains in mid-March. The winter-related events were responsible for at least 358 fatalities, making it the deadliest season since 1992–93. A La Niña pattern influenced much of the winter in North America.
The October 2017 North American storm complex was a major explosive cyclogenesis storm, also called bomb, in the Northeastern United States and Atlantic Canada from October 29–31, 2017. Forming from an extratropical cyclone on October 29 the system moved rapidly up the East Coast of the United States, bombing out with a minimum pressure of 975 millibars (28.8 inHg) on October 30. It brought heavy rain and extremely strong winds, and power outages, over 1.3 million customers being without power in the Northeast. Hurricane-force wind gusts resulted in downed trees, power lines, and widespread damage to buildings. The number of power outages in the state of Maine surpassed the Ice Storm of 1998.
The May 2022 Canadian derecho was a high-impact derecho event that affected the Quebec City-Windsor Corridor, Canada's most densely populated region, on May 21, 2022. Described by meteorologists as a historic derecho and one of the most impactful thunderstorms in Canadian history, winds up to 190 km/h (120 mph) as well as around four tornadoes caused widespread and extensive damage along a path that extended for 1,000 kilometres (620 mi).
