Hurricane Gloria was a powerful hurricane that caused significant damage along the east coast of the United States and in Atlantic Canada during the 1985 Atlantic hurricane season. It was the first significant tropical cyclone to strike the northeastern United States since Hurricane Agnes in 1972 and the first major storm to affect New York City and Long Island directly since Hurricane Donna in 1960. Gloria was a Cape Verde hurricane originating from a tropical wave on September 16 in the eastern Atlantic Ocean. After remaining a weak tropical cyclone for several days, Gloria intensified into a hurricane on September 22 north of the Lesser Antilles. During that time, the storm had moved generally westward, although it turned to the northwest due to a weakening of the ridge. Gloria quickly intensified on September 24, and the next day reached peak winds of 145 mph (233 km/h). The hurricane weakened before striking the Outer Banks of North Carolina on September 27. Later that day, Gloria made two subsequent landfalls on Long Island and across the coastline of western Connecticut, before becoming extratropical on September 28 over New England. The remnants moved through Atlantic Canada and went on to impact Western Europe, eventually dissipating on October 4.
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 North American blizzard of 2006 was a nor'easter that began on the evening of February 11, 2006 and impacted much of eastern North America. It dumped heavy snow across the Mid-Atlantic and New England states, from Virginia to Maine through the early evening of February 12, and ended in Atlantic Canada on February 13. The major cities from Baltimore to Boston received at least a foot of snow, with a second-highest amount of 26.9 inches (68 cm) in New York City, the most since at least 1869, the start of record keeping, only broken by the January 2016 United States blizzard nearly 10 years later.
The Christmas 1994 nor'easter was an intense cyclone along the East Coast of the United States and Atlantic Canada. It developed from an area of low pressure in the southeast Gulf of Mexico near the Florida Keys, and moved across the state of Florida. As it entered the warm waters of the Gulf Stream in the Atlantic Ocean, it began to rapidly intensify, exhibiting traits of a tropical system, including the formation of an eye. It attained a pressure of 970 millibars on December 23 and 24, and after moving northward, it came ashore near New York City on Christmas Eve. Because of the uncertain nature of the storm, the National Hurricane Center (NHC) did not classify it as a tropical cyclone.
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 effects of Hurricane Isabel in New York and New England were relatively minor and primarily limited to wind damage. 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 mph (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 mph (169 km/h) on September 18. It quickly weakened over land and became extratropical over western Pennsylvania the next day.
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 9 tornadoes to the Southeastern United States.
The February 25–27, 2010 North American blizzard was a winter storm and severe weather event that occurred in the Mid-Atlantic and New England regions of the United States between February 24 and 26, 2010. The storm dropped its heaviest snow of 12 to 24 inches across a wide area of interior New England, New York, and Pennsylvania. The storm also brought flooding rains to coastal sections of New England, with some areas experiencing as much as 4 inches (10 cm). Aside from precipitation, the nor'easter brought hurricane-force sustained winds to coastal New England.
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 2011 Groundhog Day blizzard was a powerful and historic winter storm that affected large swaths of the United States and Canada from January 31 to February 2, 2011, especially on Groundhog Day. During the initial stages of the storm, some meteorologists predicted that the system would affect over 100 million people in the United States. The storm brought cold air, heavy snowfall, blowing snow, and mixed precipitation on a path from New Mexico and northern Texas to New England and Eastern Canada. The Chicago area saw 21.2 inches (54 cm) of snow and blizzard conditions, with winds of over 60 mph (100 km/h). With such continuous winds, the blizzard continued to the north and affected Eastern and Atlantic Canada. Blizzard conditions affected many other large cities along the storm's path, including Tulsa, Oklahoma City, Kansas City, St. Louis, Springfield, El Paso, Las Cruces, Des Moines, Milwaukee, Detroit, Indianapolis, Dayton, Cleveland, New York City, New York's Capital District, and Boston. Many other areas not normally used to extreme winter conditions, including Albuquerque, Dallas and Houston, experienced significant snowfall or ice accumulation. The central Illinois National Weather Service in Lincoln, Illinois, issued only their fourth blizzard warning in the forecast office's 16-year history. Snowfall amounts of 20 to 28 inches were forecast for much of Northern and Western Illinois.
The 2011 Halloween nor'easter, sometimes referred to as "Snowtober," "Shocktober," "Storm Alfred," and "Oktoberblast," was a large low pressure area that produced unusually early snowfall across the northeastern United States and the Canadian Maritimes. It formed early on October 29 along a cold front to the southeast of the Carolinas. As it moved up the East Coast, its associated snowfall broke records in at least 20 cities for total accumulations, resulting in a rare "white Halloween" two days later.
The December 1992 nor'easter produced record high tides and snowfall across the northeastern United States. It developed as a low pressure area on December 10 over Virginia, and for two days it remained over the Mid-Atlantic states before moving offshore. In Maryland, the snowfall unofficially reached 48 in (1,200 mm); if verified, the total would have been the highest in the state's history. About 120,000 people were left without power in the state due to high winds. Along the Maryland coast, the storm was less severe than the Perfect Storm in the previous year, although the strongest portion of the storm remained over New Jersey for several days. In the state, winds reached 80 mph (130 km/h) in Cape May, and tides peaked at 10.4 ft (3.2 m) in Perth Amboy. The combination of high tides and 25 ft (7.6 m) waves caused the most significant flooding in the state since the Ash Wednesday Storm of 1962. Several highways and portions of the New York City Subway and Port Authority Trans-Hudson systems were closed due to the storm. Throughout New Jersey, the nor'easter damaged about 3,200 homes and caused an estimated $750 million in damage (1992 USD).
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 severe 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 February 2019 North American winter storm was one of three powerful winter storms that affected the continent in early February. This storm, in particular, paralyzed travel in parts of the Midwest, Northeast as well as Eastern Canada.
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 six storms ranking on the Regional Snowfall Index scale (RSI), with four 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 December 15–17, 2020 nor'easter was a powerful nor'easter that hammered the Northeastern United States and produced widespread swaths of over 1 foot (12 in) of snow in much of the region from December 15–17, 2020, ending a 1,000+ day high-impact snowstorm drought in much of the Mid-Atlantic and coastal New England regions. The system developed out of a weak area of low-pressure that first developed over the Central United States producing some snowfall before moving eastward, and by December 16, a new, dominant area of low pressure began to develop along the Southeast coast. This low steadily deepened as it moved along and impacted the Mid-Atlantic coastline, prompting several winter-related advisories and warnings for much of the Northeast.
The October 2017 nor'easter was a major explosive cyclogenesis storm, also called a bomb cyclone, 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 2022–23 North American winter was an unusually warm winter for the east and an unusually cold winter for the west in North America, as it occurred across the continent from late 2022 to early 2023. The winter season in North America began at the winter solstice, which occurred on December 21, 2022, and it ended at the March equinox, which occurred on March 20, 2023. The first day of meteorological winter began on December 1 and unofficially ended on February 28; winter storms may still occur outside of these limits.
