WThe 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 all over 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.
WThe North Carolina ice storm of 2002 caused up to an inch of freezing rain from December 4–5 in central North Carolina. A total of 24 people were killed, and as many as 1.8 million people were left without electricity on December 6. Power outages began December 4, and power was not completely restored until December 14. Raleigh received the most freezing rain from a single storm since 1948, and Bristol, Tennessee received the most ice it had seen in 28 years. The storm also produced heavy rain in both the mountains and coastal plain of North Carolina. Much of the Southern Plains and the Northeast received snow with this system.
WThe December 2008 Northeastern United States ice storm was a damaging ice storm that took out power for millions of people in the Northeastern United States. The storm was deemed the worst ice storm in a decade for New England and the most severe ice storm in 21 years for Upstate New York. Damage was primarily a result of fallen trees and fallen utility wires and poles, which were coated in a heavy layer of ice. The storm raised heavy controversy over the slow return of power, as at the storm's peak as many as 1.7 million customers were without power. Days after the storm more than 800,000 customers were still without power. Almost a week after the storm still more than 100,000 customers were without power, affecting the holiday shopping season and crippling the business and transportation of many northeast cities for days.
WThe December 2013 North American storm complex was a significant storm complex that had all sorts 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 27 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.
WThe Mid-December 2007 North American winter storms were a series of 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.
WCyclone Carmen was an extratropical cyclone and European windstorm which crossed the Atlantic Ocean and affected the United Kingdom, Ireland, France, Belgium, and the Netherlands in November 2010.
WThe early January 2017 North American winter storm was a major snow and ice storm that affected the Lower 48 of the United States with severe weather. Moving ashore on the West Coast on January 3, the system produced heavy snowfall in the Sierra Mountains, with nearly 4 feet of snowfall falling in the highest elevations. After impacting the Northwest and Southwest, the winter storm went on to strike the Southeast on January 5–6 with snow and ice, with snowfall accumulations up to 4 inches (10 cm). Afterwards, it began to morph into a nor'easter as it moved off the Southeast coast late on January 6, while producing blizzard conditions in the Carolinas. It then began to affect the Northeastern United States as it tracked northwards early on January 7. It produced a swath of moderate snowfall accumulations up the East Coast, with easternmost areas such as parts of Massachusetts receiving up to 1.5 feet (18 in) of snow.
WThe 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.
WThe 1991 Halloween blizzard was a powerful storm that caused a period of heavy snowfall and ice accumulation, which affected parts of the Upper Midwest of the United States, from October 31 to November 3, 1991. Over the last week of October 1991, a large storm system over the Atlantic Ocean blocked most of the weather patterns over the eastern half of the United States, and in turn, moisture from the Gulf of Mexico was funneled straight northward over the affected region. By the time the precipitation stopped falling, many cities in the eastern half of Minnesota and northwestern Wisconsin had witnessed record early-season snowfall accumulations, while parts of southern Minnesota and northern Iowa were crippled by a large ice storm. Arctic air that was pulled southward behind the storm had combined with the heavy snow pack to produce many record low temperatures. Between the blizzard and the ice storm, 22 people were killed and over 100 were injured.
WThe North American ice storm of mid-January 2017 was a major ice storm that impacted the Great Plains, Pacific Northwest, and American Midwest. During the storm, multiple U.S. states declared states of emergency, and icy road conditions caused traffic incidents and fatalities. An outbreak of 11 tornadoes also struck Texas, injuring two.
