Big storm threatens US East Coast

WASHINGTON - An unusual nasty mix of a hurricane and a winter storm that forecasters are now calling "Frankenstorm" is likely to blast most of the U.S. East Coast next week, focusing the worst of its weather mayhem around New York City and New Jersey.
Government forecasters on Thursday upped the odds of a major weather mess, now saying there's a 90 per cent chance that the East will get steady gale-force winds, heavy rain, flooding and maybe snow starting Sunday and stretching past Halloween on Wednesday.
Meteorologists say it is likely to cause $1 billion in damage.
The storm is a combination of Hurricane Sandy, now in the Caribbean, an early winter storm in the West, and a blast of arctic air from the North. They are predicted to collide and park over the country's most populous coastal corridor and reach as far inland as Ohio.
The hurricane part of the storm is likely to come ashore somewhere in New Jersey on Tuesday morning, said National Oceanic and Atmospheric Administration forecaster Jim Cisco. But this is a storm that will affect a far wider area, so people all along the East have to be wary, Cisco said.
Coastal areas from Florida to Maine will feel some effects, mostly from the hurricane part, he said, and the other parts of the storm will reach inland from North Carolina northward.
Once the hurricane part of the storm hits, "it will get broader. It won't be as intense, but its effects will be spread over a very large area," the National Hurricane Center's chief hurricane specialist, James Franklin, said Thursday.
One of the more messy aspects of the expected storm is that it just will not leave. The worst of it should peak early Tuesday, but it will stretch into midweek, forecasters say. Weather may start clearing in the mid-Atlantic Nov. 1 and Nov. 2 in the Northeast, Cisco said.
"It's almost a weeklong, five-day, six-day event," Cisco said Thursday from NOAA's northern storm forecast centre near Washington.. "It's going to be a widespread serious storm."
With every hour, meteorologists are getting more confident that this storm is going to be bad and they are able to focus their forecasts more.
The New York area could see around 5 inches (127 millimeters) of rain during the storm, while there could be snow southwest of where it comes inland, Cisco said.
Both private and federal meteorologists are calling this a storm that will likely go down in the history books.
"We don't have many modern precedents for what the models are suggesting," Cisco said.
It is likely to hit during a full moon when tides are near their highest, increasing coastal flooding potential, NOAA forecasts warn. And with some trees still leafy and the potential for snow, power outages could last to the Nov. 6 Election Day, some meteorologists fear.
