NEW YORK - Another snowstorm delivered a crippling blow to the United States northeast early Thursday, dumping more than a foot of snow, closing airports and schools, stranding commuters and shattering January records. The storm seemed to land hardest in New York and the surrounding area. Nineteen inches of heavy, wet snow fell on Central Park, tied for the highest total in the region and only an inch less than the 20 inches that paralysed the city a month ago, according to the National Weather Service. But parts of Connecticut and New Jersey received nearly as much, and snowfalls totalled at least a foot from Boston to Philadelphia. New York City Mayor Michael Bloomberg declared a weather emergency. Schools and offices were closed, as were Newark, Teterboro and John F Kennedy airports. Commuter bus service was suspended throughout New Jersey, Long Island and most of New York City, as hobbled train systems struggled to absorb the overload. The storm created a fresh sense of snow fatigue in a region that has been unusually battered by storms. By suspending bus service in the city, the Metropolitan Transportation Authority avoided a rerun of the December storm, when hundreds of buses got stuck in the snow, blocking the traffic. Even before the storm started walloping the region overnight, the National Weather Service had estimated that more than 37 inches of snow - almost double the winter average - had fallen in Central Park this winter. The overnight storms broke January snowfall records for Central Park, Newark, LaGuardia Airport, Bridgeport and Islip, the Weather Service said Thursday morning. In addition to the 19 inches in Central Park, the heaviest totals included 19 inches in Clifton, NJ; 18.5 inches in North Haven, Conn.; 18.9 at Newark airport; and 16.5 inches in Northport, NY, on Long Island, the Weather Service said.
