A state of emergency was declared Tuesday in Saint John, N.B., after the third storm in less than a week pummelled the port city overnight and left its streets choked with snow.

Other areas across the Maritimes weren't spared, as road closings, school cancellations and flight delays were reported across the region.

From Montana to Maine, Americans also felt biting cold on Tuesday, with Boston rescheduling the New England Patriots' Super Bowl victory parade for Wednesday because of the weather.

NEW BRUNSWICK: PARKING RESTRICTIONS IN EFFECT

Saint John Mayor Mel Norton said the state of emergency, which allows the city to ban on-street parking, will be in effect for up to a week in the city's southern peninsula so that plows can clear heaps of snow that have reached levels not seen in recent years.

The city says as streets are returned to a stable state, they will be removed from the declaration, and the public will be notified.

The Trans-Canada Highway between Moncton and Nova Scotia has been closed, as have some roads along the coast in eastern New Brunswick.

NOVA SCOTIA: TREACHEROUS DRIVING IN HALIFAX

The streets of Halifax were slippery after ice pellets and freezing rain combined to make a frozen mess. Both Halifax and Yarmouth reported 24 centimetres of snow.

In northern Nova Scotia, another 20 to 30 centimetres of snow fell on the area with Greenwood, N.S., getting the most at 34 centimetres.

Meanwhile, winds gusting at more that 100 kilometres per hour have been reported in parts of Cape Breton.

UNITED STATES: A BIG CHILL

Frigid temperatures descended on the northern tier of the United States on Tuesday, as a biting chill followed a powerful snowstorm from the central Midwest into the Northeast, prompting warnings of flash freezing along the East Coast.

The Arctic blast brought frigid wind chills to parts of Pennsylvania, New York and the northern New England region.

School was cancelled in Boston and some suburbs for Tuesday and Governor Charlie Baker ordered a delayed start for nonessential state agency workers to allow more time for clearing roads. The storm was blamed for at least one death, a woman who was struck and killed by a snowplow in suburban Boston.

WINTER WEATHER: IT'S NOT OVER YET

Jean-Marc Couturier, a forecaster with Environment Canada in Halifax, says another low-pressure system is expected to hit the Maritimes on Thursday, bringing more snow and strong winds.
