Jeff Masters sizes up Sandy:
In a stunning spectacle of atmospheric violence, Superstorm Sandy roared ashore in New Jersey last night with sustained winds of 90 mph and a devastating storm surge that crippled coastal New Jersey and New York. Sandy’s record size allowed the historic storm to bring extreme weather to over 100 million Americans, from Chicago to Maine and from Michigan to Florida. Sandy’s barometric pressure at landfall was 946 mb, tying the Great Long Island Express Hurricane of 1938 as the most powerful storm ever to hit the Northeast U.S. north of Cape Hatteras, NC. New York City experienced its worst hurricane since its founding in 1624, as Sandy’s 9-foot storm surge rode in on top of a high tide to bring water levels to 13.88′ at The Battery, smashing the record 11.2′ water level recorded during the great hurricane of 1821. Damage from Superstorm Sandy will likely be in the tens of billions, making the storm one of the five most expensive disasters in U.S. history.

The storm has claimed at least 33 lives in the United States and has caused massive flooding across much of the Atlantic seaboard.
