NEW YORK >> The winter-weary Northeast and upper Midwest were digging out Saturday from heavy snowfall while cleanup began in battered parts of the South and Midwest after a sprawling storm system produced ferocious winds that left widespread damage and caused multiple deaths.

Snow fell across a large swath of the Northeast, from western New York to New England, with some areas expecting more than a foot of snow Saturday. The mix of snow, sleet and rain prompted the National Weather Service to warn of possible coastal flooding in Massachusetts and Rhode Island.

The storm could bring as much as 18 inches of snow to parts of New Hampshire and Maine. It also could deliver strong winds that could cause power outages.

Hundreds of businesses were closed, many flights were canceled and some bus service was suspended. The heavy, wet snow was accompanied by winds gusting to 40-50 mph, raising concerns about toppled trees and power outages, said meteorologist Jon Palmer with the National Weather Service in Maine.

In the upper Midwest, residents dug out Saturday from heavy snowfall that caused widespread power outages and forced Detroit’s Metropolitan Wayne County Airport to briefly close late Friday. Passengers were advised to check with airlines for flight delays Saturday.

An Indiana state trooper was struck by a vehicle and killed Friday afternoon while assisting other troopers with traffic backups following weather-related crashes.

Master Trooper James R. Bailey, 50, was hit while deploying stop sticks on Interstate 69 near Auburn to stop a speeding vehicle fleeing Fort Wayne police, state police said. Bailey later died at a hospital. He had spent more than 15 years with the state police. A 42-year-old Marion, Indiana, man was arrested and faces a charge of resisting law enforcement causing death to a law enforcement officer.

In Michigan, an 80-year-old man was struck and killed Friday evening by a snowplow that was backing up while clearing snow from a driveway in Ann Arbor, MLive.com reported. The snowplow driver said he didn’t know he had struck the man until a bystander got his attention, police said.

Victoria Burnett felt a sense of foreboding as snow began falling Friday in Farmington Hills, northwest of Detroit. Burnett lost power for seven days following the first of two ice storms that slammed Michigan two weeks ago. She was able to use a generator until her service returned.

“At the end of the ice storm — Sunday and Monday — I was starting to get very depressed,” Burnett said Saturday. “When it started snowing (Friday) and I saw it was heavy, wet snow, I was really worried.”

Burnett said her lights flickered, but the power remained on.

The sprawling storm system spawned straight-line winds, possible tornadoes and powerful thunderstorms in the South on Friday.

At least five deaths were reported in hard-hit Kentucky, Gov. Andy Beshear said Saturday. The storm, with wind gusts surpassing 70 mph, downed trees and power lines and damaged homes and other buildings.

“This is very significant, widespread damage throughout Kentucky,” Beshear said.

In central Tennessee, where the severe weather took down power lines and damaged homes, at least two deaths were blamed on the storm. In both cases, the victims were struck by falling trees, authorities said.

About 780,000 utility customers in Kentucky, Tennessee and Michigan were without power, according to PowerOutage.us. More than 350,000 of those cutomers were in Kentucky, and the governor warned it would take days to fully restore service.

Kentucky’s electric cooperatives reported hundreds of snapped utility poles and thousands of power lines down across the Bluegrass State. Soft ground from heavy rains slowed the progress of heavy equipment to access damaged infrastructure.

At the height of the windstorm, more than 300,000 consumer-members lost power in Kentucky, the co-ops said. By early Saturday afternoon, about 148,000 members remained without power.

“The damage from this event is as widespread as any natural disaster I have ever seen in Kentucky co-op history,” said Chris Perry, president and CEO of Kentucky Electric Cooperatives.

In Alabama, a 70-year-old man sitting in his truck in Talledega County was killed when a tree fell onto his vehicle. A 43-year-old man in Lauderdale County and a man in Huntsville also were killed by falling trees Friday, local authorities said.
