Snowfall of 8 to 12 inches was forecast in central Massachusetts and parts of Rhode Island by Friday morning, with 6 to 10 inches in Boston and nearby areas.
National Weather Service meteorologist Alan Dunham says it will be a "conveyor belt of wave after wave of snow" coming in. "That will be continuing all night," he added.
But powerful ocean waves and high winds were expected to cause more trouble than snow from Rhode Island to Maine. A coastal flood warning was in effect for east-facing shores in Massachusetts, with possible 3-foot surges at high tide.
The late-winter storm that buried parts of the Midwest and Mid-Atlantic swept into New England on Thursday, and the region braced for the brunt of the storm overnight into Friday.
"The main problem," explains meteorologist Terry Eliasen, executive weather producer of CBS Boston station WBZ-TV, "is the persistent, strong east wind just will not relent, so the water which rushes in for high tide will not ever be able to fully escape back out to sea.
"Each successive high tide will only get worse, with a peak coming Friday morning.
"Astronomically speaking, Friday's 8 a.m. high tide is the greatest of the bunch and it will come after 48 hours of pounding easterly winds," Eliasen concluded.
The current forecast is for moderate to major coastal flooding, rivaling that of the blizzard about a month ago. Wave heights will be an astounding 25-to-30 feet just offshore. The beach erosion will be massive. Our coastline has been reshaped forever with all these recent storms and this event will likely be the worst yet.
In the seacoast town of Scituate, Mass., about 30 miles south of Boston, about a dozen streets were closed after Thursday morning's high tide sent 2 to 2-1/2 feet of water washing into some areas.
Emergency management officials said the evening tide brought fewer problems, but they worried about getting through Friday morning's high tide, before the storm was expected to wind down. No severe flooding was reported elsewhere.
"There are no mandatory evacuations, but it is strongly advised," said Scituate Police Chief Brian Stewart. "Why put yourself at risk? Folks have been through this before, and they know what happens in these areas. We're recommending that people in areas that have experienced coastal flooding to evacuate three hours before high tide."
In Salisbury, Mass., on the New Hampshire border, officials ordered evacuations for homes along several beachfront streets.
On Cape Cod, where the storm was expected to be mostly rain, officials were concerned about beach erosion. The area suffered extensive erosion from superstorm Sandy in October and a major snowstorm last month.
"We've really gotten more erosion in the last six months than we've experienced in the last decade," said Sandwich Town Manager George Dunham. "These three storms are really taking a toll."
Some in Massachusetts were taking the storm in stride.
Mail carrier Stephen Manning didn't even wear a coat as he delivered mail along Dorchester Avenue in Boston. Instead, he wore a hooded sweatshirt.
"This is warm," Manning said. "You wear a jacket when it's cold."
Dozens of car crashes were reported across Connecticut on Thursday morning. A FedEx tractor trailer overturned on Interstate 84 in Tolland, causing a chain-reaction crash involving about nine other vehicles, including a state police cruiser and two other tractor-trailers. No serious injuries were reported.
The storm pummeled the nation's midsection Tuesday, killing at least five people in weather-related traffic accidents.
On its way north, it called on Mantoloking, N.J., the shore town hit hardest by Superstorm Sandy. A pounding surf broke through a temporary dune during the early-morning high tide Thursday. The dune breach forced the closing of a major coastal highway for several hours.
In Virginia, three people were killed, including a 22-year-old man who died Thursday after his vehicle ran off an icy road, went over an embankment and landed upside down in a creek. No details were immediately available on the other two storm-related deaths.
Virginia Gov. Bob McDonnell declared a state of emergency and National Guard soldiers were sent to help clear roads. Up to 20 inches of snow piled up in central and western parts of the state. About 120,000 customers remained without electricity by mid-day Thursday, down from more than 200,000 outages at the height of the storm.
The storm dumped 2 feet of snow in parts of neighboring West Virginia, closing schools in more than half the state and leaving more than 20,000 customers without power.
A Coast Guard search for a missing North Carolina man and his nephew was called off Thursday. The Coast Guard said it had searched over 560 square miles of the Atlantic before suspending the search for Walter and Steven Tate, both of New Bern, N.C. A third crew member was rescued Wednesday afternoon.
Their 67-foot Seafarer became disabled Wednesday and was being towed by another ship about 15 miles east of Assateague Island when the two vessels became separated in heavy seas.
