The North American blizzard of 2009 is a severe nor'easter that formed over the Gulf of Mexico in December 2009[6] and dropped snow in North Carolina, Kentucky, Tennessee, 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 about 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 the afternoon of 19 December, 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] Blizzard warnings were issued for many of the heavily affected areas, including Baltimore, Long Island, New York, and Washington, D.C.[1]

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] 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 26.3 inches (67 cm) of snow, the deepest since 1940.[10]

In Philadelphia, snowfall reached more than 2 inches (5.1 cm) per hour, disrupting Interstate 95.[1] By Sunday (December 20), snowfall there reached 23.2 inches (59 cm), surpassing the 21 inches (53 cm) snowfall of February 11–12, 1983, as the city's second-largest, and breaking 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), Asheville, North Carolina accumulated up to 12 inches (30 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]

By Sunday morning, over 11 inches (28 cm) of snow fell in Boston, Massachusetts.[13]

Winter storm warnings for New York and Blizzard Warning for Long Island expired at 11 a.m. 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.[14] 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.[15][5]

Some areas saw winds up to 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.[16] President Barack Obama, arriving at Andrews Air Force Base after the UN Climate Conference, was forced to return to the White House by motorcade instead of helicopter.[17] More than 800 flights were canceled at New York City's three major airports.[18]

Trains were also canceled or delayed. Washington, D.C.'s Metrorail service was suspended to all outdoor stations at 1 pm on December 19.[16] One Amtrak train, carrying 255 passengers, halted for six hours while a frozen track switch was fixed.[9]

On roads, snow plows were unable to keep up with fast snow accumulations. Road accidents and stuck vehicles further hindered snow removal. On some major highways, traffic slowed to five miles per hour. [19] 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.[20]

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.[21] States of emergency were declared in Kentucky, Maryland, Virginia, West Virginia and New Castle and Kent counties in Delaware.[20]

The storm is reported to have caused five deaths: four in automobile accidents in Ohio and Virginia and one from exposure in Virginia.[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.[22] It is estimated that 30% of this revenue comes from the northeastern United States.[21] Stores that managed to open saw reduced traffic.[23]
