Sandy is moving slower now, but the storm is still packing high winds, rain, and snow on Tuesday, extending from New York City to Lake Michigan.
The storm that was Sandy isn't done just yet.
After lashing coastal cities and inundating parts of New York City with 13 feet of water, the core of the hybrid storm is beginning a long slog across Pennsylvania and upstate New York, with its effects spreading as far west as Wisconsin and Illinois.
"This is going to be an event that for a period of time is going to alter the way we do things," Pennsylvania Gov. Tom Corbett said Monday, warning residents of his state they would not escape with just a glancing blow.
By midnight, what's left of Sandy was near Philadelphia and was forecast to spend most of Tuesday heading across Pennsylvania and then take a sharp turn Wednesday into western New York, weakening as it moved, said Daniel Brown, a hurricane specialist at the National Hurricane Center.
The once-tropical system has merged with a wintry cold front and is likely to produce heavy rain in the East for the next two or three days — adding up to more flooding, Brown said.
