"There are no precedents for Sandy," Bill Read, former director of the National Hurricane Center told the Houston Chronicle.
That's because, according to science writer Eric Berger, "it's unprecedented for a storm to strike the mid-Atlantic states moving due west at landfall." Sandy is also remarkable, because she set the record for the lowest pressure of an Atlantic storm north of North Carolina and became the second largest Atlantic tropical cyclone since 1988. Superstorm Sandy is also much larger than other hurricanes -- also twice the size of Hurricane Ike!
4. Record-Setting Snowfall
As superstorm Sandy moves north, western North Carolina is seeing very atypical snowfall, the National Weather Service reported. Tuesday mornings' snowfall in the mountains was as much as five inches in the region, and residents are still expecting more. The weather service said that up to six inches of snow could fall in the region, which hasn't happened in Western North Carolina at this time of year since 1923, according to local NBC affiliate WYFF 4.
The snow has already caused power outages to about 4,000 homes in the region, and weathermen warn locals of icy, slippery roadways in the area.
5. Record Flooding And Associated Costs
Forecasters said it would be bad, but not this bad. Various meteorologists predicted that Sandy would bring a storm surge into New York Harbor on Monday evening between 6 and 10 feet. But, just after 7 p.m. on Monday evening, The Weather Channel reported that the surge in Battery Park had reached 14 feet, and had broken a record high set in 1821. The East River also reportedly crept into the East Village of Manhattan on Avenue C, and the Hudson River overflowed into the streets of lower Manhattan. Property damage caused by standing water and strong winds in New York and New Jersey will likely cost insurance providers billions of dollars.
Last year's Hurricane Irene, a significantly gentler storm, cost insurance companies more than $4 billion in damage claims, according to TIME Magazine. Some analysts have put Sandy's damages somewhere between $5 and $10 billion dollars, making it one of the top 10 most expensive storms in U.S. history.
"We knew that this was going to be a very dangerous storm, and the storm has met our expectations," Bloomberg said in a press conference on Monday evening. "This is a once-in-a-long-time storm."
