Heavy rain leads to major flooding, closed roadways in Northeast

Heavy rain spawned extreme flooding in New York's Hudson Valley that killed at least one person, swamped roadways and forced road closures on Sunday night, as much of the rest of the Northeast U.S. prepared for a major storm.

The National Weather Service issued flash flood warnings across parts of southeastern New York, describing it as "life-threatening," as well as warnings in northeastern New Jersey.

Orange County Executive Steve Neuhaus told CBS New York a woman in her mid-30s and her dog were swept away by floodwaters while she was evacuating her house in Highland Falls. The woman was later found dead. Neuhaus said the dog was found safe and taken in by a neighbor.
