Anyone who's ever lived in a chilly climate knows snowstorms well. Sometimes the weather forecast gives ample warning, but other times these storms catch us by surprise. Plows struggle to keep roads clear, schools are closed, events are canceled, flights are delayed and everyone gets sore backs from all the shoveling and snowblowing.
But there are those rare snowstorms that exceed all forecasts, break all records and cause mass devastation (even if it's devastation that will melt in a few days or weeks). These storms are the worst of the worst, weather events that seem more like elemental blasts of pure winter rather than a simple combination of wind, temperature and precipitation.
Defining the 10 "biggest" snowstorms can be a tricky task. You can't simply rely on objective measures like the amount of snow. Often, the worst storms involve relatively modest snowfalls whipped into zero-visibility by hurricane-force winds. Some storms are worse than others because they impact major urban areas, or are so widespread that they affect several major urban areas. Timing can play a role as well -- a storm during weekday rush hour is worse than one on a Saturday morning, and a freak early storm when leaves are still on the trees can cause enormous amounts of damage. In fact, meteorologists have developed a system similar to the one used to classify hurricanes to measure the severity of winter storms. The Northeast Snowfall Impact Scale (NESIS) takes in account a variety of factors and generates a single number that signifies a storm's severity, usually on a scale from one to 10 -- and sometimes higher.
10. The Blizzard of 1888 -- Northeastern United States
This
snowstorm was so massive it became a historical event. In terms
of storm severity factors, this one had it all: enormous amounts of
snow, frigid temperatures, howling winds whipping up monstrous snow
drifts -- and a widespread area of effect that covered the entire
northeastern United States from New England to the Chesapeake Bay,
including major metropolitan areas like New York City. More than 400
people died during the storm, including more than 100 who were lost at
sea.
The storm struck in early March and started out as a serious rain storm. From Sunday night to Monday morning, the temperature plummeted and the rain turned to snow. In the end, New York City received 22 inches (56 centimeters) of snow, shutting the city down and causing floods when the snow melted. Other places received much more: 58 inches (1.5 meters) of snow in Saratoga Springs, N.Y., and 45 inches (1.14 m) in New Haven, Conn. Snow drifts as high as 50 or 60 feet (15.2 to 18.3 m) were reported on Long Island, and wind gusts were reported as fast as 80 mph (128.7 kph).

9. The Storm of the Century, 1993 -- Eastern United States
In 1993, an early March storm surged up the east coast of the United States,
unleashing snow and wind on a wider area than any other storm in
recorded history. Massive snowfalls were recorded from eastern Canada to
Alabama. Parts of 26 states were hit; roughly half of the entire U.S.
population was affected, including many large cities.
Two hundred and seventy Americans were killed. This storm is often
compared to the Blizzard of 1888 -- in many areas, it wasn't as severe
and didn't drop as much snow, but it covered a much larger area.
This storm broke numerous weather records. A low temperature of minus 12 degrees Fahrenheit (minus 24.4 degrees Celsius) was recorded at Burlington, Vt., while even Daytona Beach, Fla., felt the effects, with a low of 31 degrees Fahrenheit (minus 0.56 degrees Celsius). Birmingham, Ala., received more than a foot of snow (30.5 cm), with four inches (10.2 cm) falling as far south as Atlanta, Ga. Snowfall totals were amplified farther north -- Syracuse, N.Y. got more than 40 inches (1.02 m), for example. Mountainous areas in the Appalachians and Catskills got the most snow, with recorded totals of 50 inches (1.27 m) or more. Wind speeds topped 70 mph (112.7 kph) in many places, and topped 100 mph (161 kph) in a few locations. Using storm surge and barometric pressure data, meteorologists say the Storm of the Century was the equivalent of a category three hurricane; it ranked a 13.2 on the NESIS scale.

8. New York City Blizzard of 2006
This storm was relatively mild; it covered a smaller area than other
major snow storms and didn't have high winds. In fact, it wasn't
technically a blizzard at all, since the scientific definition of a
blizzard requires sustained wind speeds above 35 mph (56.3 kph) and
visibility under 500 feet (152.4 meters). But this storm is notable for
the one place it did hit: New York City.
The weather station at New York's Central Park Zoo recorded a total of 26.9 inches (68.3 cm) of snow from the storm. That total equals the greatest snowfall in New York City recorded history and breaks a record that had been set in 1947.
7. Lhunze County, Tibet -- 2008

7. Lhunze County, Tibet -- 2008
Tibet is known for some of the world's tallest mountains, including Mount Everest.
It gets bitterly cold there in the winter, but the climate is generally
very arid. Some passes through the Himalayas remain passable throughout
the year because of the low snowfall rates. For that reason, the snow
storm that hit Lhunze County in October 2008 was a shock to its
citizens.
Chinese officials reported an average snow depth of 59 inches (1.5 m). Some villages experienced continuous snow for 36 hours, dropping five or six feet (1.52 or 1.83 m) of snow on the ground. The amount of snow was so great that many buildings collapsed, resulting in seven deaths. Roads were closed for days as rescue crews fought to clear them and bring food to people trapped by the storm.
The economic effects of the storm were particularly harsh, as many locals were forced to slaughter or sell off large parts of their yak herds, or lost them entirely in the storm's aftermath.
6. Mount Shasta, Calif. -- 1959
In 1959, a storm dumped a huge amount of snow on Mount Shasta, Calif. The 189 inches (4.8 m) of snow recorded at the Mount Shasta Ski Bowl is the largest snowfall from a single storm in North America. However, many believe that 1993's "Storm of the Century" has eclipsed this mark in terms of the actual volume of snow, due to heavy snowfall across such a massive area.

Oddly enough, the
storm didn't have
much of an effect on locals. For one thing, residents of the Mount
Shasta area were used to big snowstorms, so aside from some delays while
they waited for plows to clear the wet, heavy snow, it didn't affect
them much. Also, the bulk of the snow fell away from the communities of
Weed and Mount Shasta City, covering unpopulated mountainous areas. Few
people at the time even noted that the town had broken the single storm
snowfall record.
5. The Eastern Canadian Blizzard of 1971 -- Quebec and Ontario, Canada
5. The Eastern Canadian Blizzard of 1971 -- Quebec and Ontario, Canada
This March nor'easter (a powerful storm that blows in from the
Atlantic Ocean) created classic blizzard conditions throughout eastern Canada,
dumping a foot and a half (45.7 cm) of snow on Montreal and more than
two feet (61 cm) elsewhere in the region. On top of the snowfall, the
storm produced heavy winds that whipped the snow into the air and
obliterated visibility. These conditions, combined with frigid
temperatures, resulted in more than 20 fatalities.
Although many Canadians took the wintry blast in stride -- residents of Cornwall, Ontario were encouraged to come to work despite the storm -- this blizzard caused a event virtually unheard of in Canadian history: the cancellation of a Montreal Canadiens hockey game. It was the first time that a game at the Montreal Forum had been postponed since the flu epidemic of 1918.
4. The New England Blizzard of 1978
This dreadful storm stalled over New England for more than a day, dropping up to 4 inches (10.2 cm) of snow per hour. Boston, Mass. and several communities in Rhode Island were hit hardest, but even New York City -- located some four hours south of Boston -- felt the storm's effects. Meteorologists estimate snow totals between 1 and 3 feet (30.5 and 91.4 cm), with Boston's total accumulation of 27.1 inches (68.8 cm) setting the city's single-storm record. Wind speeds measured well over 100 mph (161 kph), causing severe visibility and drifting problems.
