The unseasonable October storm that has dumped up to 70 centimetres of snow on parts of the northeastern United States surged into Atlantic Canada on Sunday, peppering areas with snow, rainfall and fierce winds.

Jay Scotland, CBC weather analyst, said the storm is bringing a mixed bag of weather.

"It depends where in the Maritimes you are," Scotland said. "It's a wind, rain and snow event."

Environment Canada put a snowfall warning in effect for Fredericton and the surrounding area, where flurries began overnight, but it was lifted Sunday night.

NB Power reported more than 3,300 outages Sunday evening in the areas of Fredericton, Miramichi, Moncton, Bouctouche and Rothesay.

High winds and pounding surf caused a boat carrying two men to crash against the rocks near the Royal Kennebeccasis Yacht Club in Saint John. The men were able to get to shore on their own. They were wet and cold, but otherwise OK.

RCMP believe road conditions may have been responsible for a three-vehicle crash near Kent Junction, N.B., in which three people were killed.

A snowfall warning is still in effect in several areas of Newfoundland. Those regions will see up to 15 centimetres of snow into Sunday evening, tapering off overnight. Winds gusting up to 120 km/h are expected in coastal areas.

On Prince Edward Island, the forecast calls for an additional 20 to 30 millimetres of rain Sunday evening, with coastal winds clocking 100 km/h but expected to diminish overnight. There were 2,000 Maritime Electric customers without power Sunday evening in the areas of East Point and Grand Tracadie.

Elsewhere, some of Nova Scotia was under wind warnings Sunday, with Environment Canada predicting gusts of up to 100 km/h and pounding surf in coastal areas. Rainfall all day Sunday in Halifax caused flooding in some streets.

"For Nova Scotia, this is mainly going to be a wind event for you, with a lot of rain to go along with it," Scotland said. "So the rain will be falling sideways, not vertically."

The Cobequid Pass toll plaza on Highway 104 saw snow, rain and high winds. The CBC's Donna Allen reported early Sunday evening there was heavy rain on either side of the pass with snow on the top of the pass. Road conditions were slippery in places.

Early Sunday evening, more than 35,000 customers were without power in the Nova Scotia communities of southern Cape Breton, Chester, Dartmouth, Bridgetown, Digby, Barrington, Kentville, Cheticamp and Ingonish.

Rough seas forced Northumberland Ferries to suspend service all day Sunday between P.E.I. and Nova Scotia. Confederation Bridge was closed to high-sided vehicles most of Sunday afternoon and into the evening due to strong gusts between 80 to 105 km/h.

The storm's effects were being felt as far away as Quebec City, which saw flurries early Sunday morning.

Storm linked to 3 deaths in U.S.

The storm dumped heavy, wet snow across the eastern United States on Saturday, knocking down trees and power lines and cutting electricity to more than three million homes and businesses.

It was linked to at least three deaths, including an 84-year-old man in Pennsylvania who was killed when a snow-covered tree fell on his home. 

In Massachusetts, authorities say a 20-year-old man died in Springfield after being electrocuted by a power line downed by high winds and wet, heavy snow.

And in Connecticut, Gov. Dannel Malloy said one person died in a traffic accident in the state that he blamed on slippery conditions.

Areas in the northern U.S. received nearly 70 centimetres of snow and a state of emergency was declared in New Jersey. Connecticut and Massachusetts also declared states of emergencies.

The storm disrupted air travel along the Eastern Seaboard, and lengthy delays were reported at airports in New York, Pennsylvania and New Jersey.
