Chilly winter-style weather, mixed with heavy rain and snow is due to arrive in Atlantic Canada Sunday as a storm moves north after rolling over the U.S. East Coast.

Environment Canada has issued snowfall and rainfall warnings for several areas in New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland.

The anticipated snowstorm is an offshoot of a storm moving up the U.S. East Coast. It is expected to combine with a cold air mass and coat the country's northeast states with snow before moving up to Canada.

Environment Canada said heavy rainfall is expected to douse much of the area with snow projected in parts of New Brunswick as well as Newfoundland.

The forecaster posted rainfall warnings calling for between 40 and 50 millimeters of rain in Nova Scotia, southern New Brunswick and Prince Edward Island.

A low pressure system near Cape Hatteras was expected to intensify as it moved towards the Maritimes, bringing the precipitation and strong coastal winds.

Parts of New Brunswick are under a snowfall warning, with Fredericton and area expecting 10 to 15 centimetres of snow.

Newfoundland is expected to get between 15 and 25 millimetres of rain on Sunday before changing over briefly to snow on Monday.

Numerous flights to New York and Newark were cancelled or delayed from airports in Toronto, Montreal, St. John, New Brunswick and Halifax.

U.S. buried by storm

The powerful nor'easter dumped heavy snow on sections of the U.S. mid-Atlantic region Saturday, knocking out electricity to some 1.7 million customers in a wide area from Maryland to Massachusetts.

The bizarre storm also prompted regions including New Jersey and Connecticut to declare states of emergency.

Some areas were hit with more than 15 centimetres of snow, while towns near the Maryland-Pennsylvania border saw 25 centimetres fall. And New York City's Central Park set a record for October with some 3.3 centimetres of snow measured by mid-afternoon.

"This is absolutely a lot more snow than I expected to see today. I can't believe it's not even Halloween and it's snowing already," Carole Shepherd of Washington Township, N.J., said after shoveling her driveway.

Travel was disrupted along the eastern seaboard with long delays reported at airports such as Philadelphia International Airport, Newark Liberty International Airport and John F. Kennedy International.

Train service was also disrupted on numerous lines due to fallen trees and signal problems.
