WASHINGTON (AP) — An unusual nasty mix of a hurricane and a winter storm that forecasters are now calling "Frankenstorm" is likely to blast most of the 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 percent 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 damages.
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're 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 won't 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 the day after Halloween and Nov. 2 in the Northeast, Cisco said.
