High tides washed through the streets of Jersey Shore towns, mixing with snow and pooling in driveways, televised images showed. Video footage on CNN showed water pouring into downtown Margate, New Jersey, near Atlantic City, an area still recovering from Superstorm Sandy three years ago.

The heaviest snow was engulfing New York City on Saturday but was expected to ease by early afternoon, though not end until Sunday.

At least six people were killed in car crashes due to icy roads in North Carolina, Kentucky and Tennessee.

The worst appeared to be over for Washington, although moderate snow was expected to keep falling until late Saturday, with the deepest accumulation of 23 inches recorded in Poolesville, Maryland, north of the nation's capital.
