The North American blizzard of 2009 was a severe nor'easter that formed over the Gulf of Mexico in December 2009[6] and dropped snow in North Carolina, Kentucky, West Virginia, Virginia, Washington, D.C., Maryland, Delaware, Ohio, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, Massachusetts, and Nova Scotia.[1][3][7] The storm produced whiteout conditions in many areas, and dumped more than 16–20 inches (41–51 cm) of snow in many places, including major cities along the Eastern seaboard.

Formation

On December 16, 2009, meteorologists identified a storm forming in the Gulf of Mexico. It produced record rainfall in some areas of Texas, and had the potential to strengthen as it moved through Georgia and Florida and further north. Weather models accurately predicted that this storm would meet with cold air while retaining its record precipitation.[1] By Saturday afternoon, the large, low pressure region had moved up the east coast beyond Virginia, intensifying over the Washington Metropolitan Area and producing snow along its path.[7][8]

Snowfall

The storm produced record 24-hour snowfall in Washington, D.C. and Roanoke, Virginia, where nearly 2 feet (0.61 m) of snow accumulated. Some interior areas of West Virginia saw 30 inches (76 cm) of snow.[3] Blizzard warnings were issued for many of the heavily affected areas, including Baltimore, Long Island, New York, and Washington, D.C.[1] The storm broke the record for the amount of snow in a single event in December at Ronald Reagan Washington National Airport, where 16.3 inches (41 cm) of snow accumulated. The storm was also the 6th greatest snowfall in D.C. history.[8][9] The National Weather Service in Brookhaven, New York reported 25 inches (64 cm) of snow, the deepest since 1940.[10]

In Philadelphia, snowfall rates reached more than 2 inches (5.1 cm) per hour, resulting in disruption of Interstate 95.[1] By Sunday, the total snowfall in Philadelphia reached 23.2 inches (59 cm), which surpassed the snowstorm of February 11–12, 1983, which dumped 21 inches (53 cm) on the city, as the second-largest in city history, as well as exceeding a 100-year-old record for the largest single December storm, set on December 25–26, 1909 with 20.2 inches (51 cm). The largest storm in Philadelphia history was the North American blizzard of 1996, which produced 30.7 inches (78 cm) of snow.[11]

In more mountainous areas, snowfall was even heavier. By midnight Saturday morning, snowfall in Boone, North Carolina had reached 14–18 inches (36–46 cm), while Greensboro, North Carolina received 3–7 inches (7.6–17.8 cm). Portions of eastern Kentucky received as much as 16 inches (41 cm).[12]

Kevin Witt, a meteorologist for the National Weather Service, said that when the snow finished falling, it could rank in the top 10 winter snowstorms in the region.[13]

By Sunday morning, over 7 inches (18 cm) of snow fell in Boston, Massachusetts.[14] Winter storm warnings for New York and Long Island expired at 11 a.m. ET Sunday, and warnings for the Boston, Massachusetts, metro area and much of southeastern New England expired at noon. A blizzard warning for Cape Cod expired at 1 p.m.[15] The storm is expected to reach southwestern portions of Nova Scotia, delivering up to 25 centimetres (9.8 in) of snow in Digby, Yarmouth, Shelburne and Queens counties. Portions of Newfoundland and Labrador are expected to receive freezing rain.[16][5]

Impact

In addition to snowfall, the nor'easter produced winds that in some areas reached 25–30 miles per hour (40–48 km/h), with gusts of 45–50 miles per hour (72–80 km/h).[3] Many places saw whiteout conditions, including Washington National Airport, Washington Dulles International Airport, and Baltimore/Washington International Thurgood Marshall Airport, where many flights were delayed or canceled. Of 740 scheduled departures at Washington National and 530 at Dulles, only 14 and 12, respectively, were able to take off.[17] President Barack Obama, arriving at Andrews Air Force Base after the UN Climate Conference, was forced to return to the White House by motorcade in lieu of flying back in Marine One.[18] More than 800 flights were canceled at New York City's three major airports.[19]

Rail services also encountered problems. Washington, D.C.'s Metrorail service was suspended to all outdoor stations at 1 pm on December 19.[17] Regular rail services encountered problems as well. One Amtrak train was forced to a halt for six hours with 255 passengers on board while a frozen track switch was fixed.[9]

The storm also impacted road travel conditions, as snow plows were unable to keep up with fast snow accumulations. In some areas, traffic slowed to five miles per hour on major highways. Accidents on roadways compounded traffic issues, as some drivers decided to venture out into the storm which resulted in many vehicles becoming stuck in the snow, or otherwise disabled, hindering efforts to remove snow from the roads.[20] Greyhound Lines canceled 294 routes through Maryland, Virginia, Washington, D.C., and West Virginia on the 19th and suspended service in and out of New York late Saturday.[21]

Thousands of power outages were reported in Virginia, Kentucky, and North Carolina, reportedly caused by snow weighing down on tree branches. By midnight Saturday morning, when the storm had just begun to strike the area, reported power outages had already exceeded 40,000.[1] In Kentucky, 107,000 power outages were reported.[12] A snow emergency was declared in Washington, D.C., where Mayor Adrian Fenty asked residents to avoid venturing onto the roads.[22] States of emergency were declared in Kentucky, Maryland, Virginia, West Virginia and New Castle and Kent counties in Delaware.[21]

The storm is reported to have caused at least five deaths. Four of the deaths were caused by storm related automobile accidents in Ohio and Virginia. One death in Virginia was related to exposure to the storm.[4]

The nor'easter, which arrived on the last shopping weekend before Christmas, hurt sales at many retail stores, but boosted online sales. Super Saturday, the last Saturday before Christmas, typically nets $15 billion in retail sales.[23] It is estimated that 30% of this revenue comes from the northeastern United States.[22] Stores that managed to open saw reduced traffic.[24]
