The Nor'easter of 2007 is steadily winding down, but will continue to bring high winds, minor coastal flooding, and up to one inch of rain to portions of the Northeast U.S. today. The nor'easter brought the heaviest rains since 1882 to New York City and northern New Jersey, triggering widespread flooding that will cost hundreds of millions of dollars. Hoboken, NJ became an island when roads surrounding the city flooded up to three feet deep, submerging cars, basements and parking lots. Over 1400 people were evacuated from homes along the Raritan River in New Jersey, which crested 10.5 feet above flood stage. At least 5000 people were evacuated in New Hampshire due to flooding, and over 400 roads closed. A woman and her 4-year-old granddaughter died when they were swept into fast-moving floodwaters as they tried to cross a washed-out section of a road in Lebanon, Maine, near the New Hampshire border. Winds gusting to 60 mph knocked out power to over 123,000 homes in Maine, the second largest power outage in state history. The record was set during an ice storm in 1998 that knocked out power to 340,000 homes.
Along the Massachusetts coast, tidal flooding has been minor to moderate, with overwash and erosion of dunes, flooding of coastal roads and some homes, but minimal damage to buildings. The peak storm surge in Boston at high tide was 2.2 feet yesterday, which added to the regular high tide to bring a 13.2 foot storm tide. Tonight's high tide may bring a storm tide half a foot higher, leading to moderate flooding. The new moon will bring a slightly higher high tide tonight than yesterday, and winds will remain gale-force, pushing 20-foot waves against the coast. Maine has already seen its highest storm surge from the storm--2.5-3.5 feet of surge during high tide yesterday. This was the fourth highest storm surge along the Maine coast since 1990. Storm surges of 1.5-2 feet are likely along the Maine coast during today's high tide cycles. Storm surges of 1-2 feet are likely at high tide today in New York City and Long Island Sound, which will cause additional minor to moderate flooding. The storm caused major erosion at Jones Beach, Robert Moses State Park and beaches in Montauk on Long Island.
Winds and snow
Tupper Lake, NY recorded 26 inches of snow. Winds gusts of 72 mph were observed in Milton, MA; 81 mph in Cape Elizabeth, ME, and 156 mph at Mount Washington in New Hampshire.
