At least nine people died in storm-related accidents, and nearly half a million people were without electricity in Pennsylvania, New Jersey, New York and Connecticut at the peak of the storm.

The ferocious storm led to near-record numbers of 911 calls in New York. New York City experienced the second-highest volume of 911 calls ever. It got 65,000 calls between 11 p.m. Friday and 11 p.m. Saturday, second only to the 96,000 calls made during the 2003 blackout.

While the rain tapered off south of New York on Monday morning, wind-whipped precipitation continued to fall in New England.

In Boston, workers threw up sand bags around the entrance to a subway station near Fenway Park on Monday morning as the Muddy River rose and threatened the station. The Massachusetts Port Authority said the weather was causing some delays and cancellations at Logan International Airport and several low-lying roads and highway ramps in Massachusetts were closed.

There also were numerous road closures in southeastern New Hampshire due to flooding.

Schools were closed in Massachusetts, Connecticut and New York on Monday.
