A blizzard is a severe snowstorm characterized by strong sustained winds and low visibility, lasting for a prolonged period of time—typically at least three or four hours. A ground blizzard is a weather condition where snow is not falling but loose snow on the ground is lifted and blown by strong winds. Blizzards can have an immense size and usually stretch to hundreds or thousands of kilometres.
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 and subarctic 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 low visibility is called a blizzard.
The Northeastern United States blizzard of 1978 was a catastrophic, historic nor'easter that struck New England, New Jersey, Pennsylvania, and the New York metropolitan area. The Blizzard of '78 formed on Sunday, February 5, 1978 and broke up on February 7. The storm was initially known as "Storm Larry" in Connecticut, following the local convention promoted by the Travelers Weather Service on television and radio stations there. Snow fell mostly from Monday morning, February 6 to the evening of Tuesday, February 7. Connecticut, Rhode Island, and Massachusetts were hit especially hard by this storm.
The Great Blizzard of 1888, also known as the Great Blizzard of '88 or the Great White Hurricane, was one of the most severe recorded blizzards in American history. The storm paralyzed the East Coast from the Chesapeake Bay to Maine, as well as the Atlantic provinces of Canada. Snow fell from 10 to 58 inches in parts of New Jersey, New York, Massachusetts, Rhode Island, and Connecticut, and sustained winds of more than 45 miles per hour (72 km/h) produced snowdrifts in excess of 50 feet (15 m). Railroads were shut down and people were confined to their homes for up to a week. Railway and telegraph lines were disabled, and this provided the impetus to move these pieces of infrastructure underground. Emergency services were also affected during this blizzard.
The North American blizzard of 1996 was a severe nor'easter that paralyzed the United States East Coast with up to 4 feet (1.2 m) of wind-driven snow from January 6 to January 8, 1996. The City University of New York reported that the storm "dropped 20 inches of snow, had wind gusts of 50 mph and snow drifts up to 8 feet high." This storm was a classic example of a nor'easter, but the storm would not have been as historically significant without the presence of the arctic high pressure system located to the north of New York. It was followed by another storm, an Alberta Clipper, on January 12, then unusually warm weather and torrential rain which caused rapid melting and river flooding in the Northeast Floods later that month. Along with the March Superstorm of 1993 and the January 2016 United States blizzard, it is one of only three snowstorms to receive the top rating of 5, or "Extreme", on the Northeast Snowfall Impact Scale (NESIS).
The Blizzard of 2003, also known as the Presidents' Day Storm II or simply PDII, was a historic and record-breaking snowstorm on the East Coast of the United States and Canada, which lasted from February 14 to February 19, 2003. It spread heavy snow across the major cities of the Northeastern and Mid-Atlantic states, making it the defining snowstorm of the very snowy winter of 2002–2003.
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 1804 New England hurricane was the first tropical cyclone in recorded history known to have produced snowfall. An unusual late-season storm in 1804, it yielded vast amounts of snow, rain, and powerful winds across the northeastern United States. Prior to its approach towards the East Coast of the United States, it passed through the Caribbean Sea on October 4, and later emerged near Georgetown, South Carolina. By early on October 9, a trough near the Virginia Capes turned the disturbance toward New England. Soon thereafter, the hurricane's abundant moisture clashed with an influx of cold Canadian air, leading to the deepening of the resulting pressure gradient and provoking inland intensification. While situated over Massachusetts, it attained its peak intensity of 110 mph (175 km/h), undergoing an extratropical transition. Even as it drifted towards the Canadian maritimes, consequently gradually weakening, precipitation persisted for another two days before the snowstorm finally subsided on October 11.
The 1997 April Fool's Day blizzard was a major winter storm in the Northeastern United States on March 31 and April 1, 1997. The storm dumped rain, sleet, and snow from Maryland to Maine leaving hundreds of thousands without power and as much as three feet of snow on the ground.
The North American blizzard of 1947 was a record-breaking snowfall that began without prediction on Christmas and brought the northeastern United States to a standstill. The snowstorm was described as the worst blizzard in the region after that of 1888. The storm was not accompanied by high winds, but the snow fell silently and steadily. By the time it stopped on December 26, accumulation had reached 26.4 inches in Central Park in Manhattan. Similar or greater accumulations were noted in all of metropolitan New York and New Jersey, as well as in upstate New York, Connecticut, and most of the mid-Atlantic region.
The East Asian snowstorms of 2009–2010 were heavy winter storms, including blizzards, ice storms, and other winter events, that affected East Asia from 8 May 2009 to 28 February 2010. The areas affected included Mongolia, China, Nepal, the Korean Peninsula, Japan, Kuril Islands, Sea of Okhotsk, Primorsky, and Sakhalin Island.
The February 5–6, 2010 North American blizzard, commonly referred to as Snowmageddon, was a blizzard that had major and widespread impact in the Northeastern United States. The storm's center tracked from Baja California Sur on February 2, 2010, to the east coast on February 6, 2010, before heading east out into the Atlantic. Effects were felt to the north and west of this track in northern Mexico, California, and the southwestern, midwestern, southeastern, and most notably Mid-Atlantic states. Severe weather, including extensive flooding and landslides in Mexico, and historic snowfall totals in every one of the Mid-Atlantic states, brought deaths to Mexico, New Mexico, Virginia, Pennsylvania, and Maryland.
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.
Global weather activity of 2009 profiles the major worldwide storms, including blizzards, tornadoes, ice storms, tropical cyclones and other meteorogical events, from January 1, 2009, to December 31, 2009. Wintery 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. Summer storms including flooding, severe thunderstorms and extratropical cyclones are also included in this list to a certain extent.
The February 2013 North American blizzard, also known as Winter Storm Nemo and the Blizzard of 2013, was a powerful blizzard that developed from the combination of two areas of low pressure, primarily affecting the Northeastern United States and parts of Canada, causing heavy snowfall and hurricane-force winds. The storm crossed the Atlantic Ocean, affecting Ireland and the United Kingdom. The nor'easter's effects in the United States received a Category 3 rank on the Northeast Snowfall Impact Scale, classifying it as a "Major" Winter Storm.
The January 31 – February 2, 2015 North American blizzard was a major winter storm that plowed through the majority of the United States, dumping as much as 2 feet (24 in) of new snowfall across a path from Iowa to New England, as well as blizzard conditions in early February 2015. It came less than a week after another crippling blizzard which impacted the Northeast with 2–3 feet of snow. It was the first of many intense winter storms to occur in the nation during the month of February, partly in due to an ongoing cold wave that was beginning to take shape shortly after the storm subsided.
The 2009–10 North American winter saw several major blizzards affect the Northeastern United States. It refers to winter as it occurred across the North American continent from late 2009 to early 2010. While there is no well-agreed-upon date used to indicate the start of winter in the Northern Hemisphere, there are two definitions of winter which may be used. Based on the astronomical definition, winter begins at the winter solstice, which in 2009 occurred on December 21, and ends at the March equinox, which in 2010 occurred on March 20. Based on the meteorological definition, the first day of winter is December 1 and the last day February 28. Both definitions involve a period of approximately three months, with some variability.
The 2019–20 North American winter was unusually warm for many parts of the United States; in many areas, neutral ENSO conditions controlled the weather patterns, resulting in strong El Niño like conditions and the sixth-warmest winter on record, and many areas in the Northeastern United States saw one of the least snowy winters in years. In fact, Baltimore and Islip saw no snow in February for the first time. Some notable events still occurred, such as a powerful blizzard that impacted the Western United States in late November, a series of cold shots in January and February, a snowstorm within the Texas Panhandle and a late-season blizzard in the High Plains.
The January 2022 North American blizzard caused widespread and disruptive impacts to the Atlantic coast of North America from northern Delaware to Nova Scotia with as much as 2.5 feet (30 in) of snowfall, blizzard conditions and coastal flooding at the end of January 2022. Forming from the energy of a strong mid- to upper-level trough, the system developed into a low-pressure area off the Southeast United States on January 28. The system then quickly intensified that night as it traveled northeast parallel to the coast on January 29, bringing heavy snowfall blown by high winds to the upper East Coast of the continent. Further north, it also moved inland in Maine and its width meant it strongly impacted all three of Canada's Maritime provinces. In some areas, mainly the coastal regions due to the wind, areas of New Jersey, Long Island and Massachusetts, it was the first blizzard since a storm in January 2018. The storm was considered a "bomb cyclone" as it rapidly intensified and barometric pressure dropped at least 24 millibars over a 24-hour period. The storm was given names such as Blizzard of 2022 and Winter Storm Kenan.
The Great Snowstorm of 1944 was a disruptive winter storm that brought high winds and between 12 and 30 inches of snow to the eastern Great Lakes region of North America between Sunday, December 10, and Wednesday, December 13, 1944. The areas most affected included northeastern Ohio, western Pennsylvania, West Virginia, upstate New York, southern Ontario and southern Quebec.
