Atlantic Canada will start the week with unsettled weather due to a potent system tracking into the region. The winds will be far-reaching and potentially damaging in many areas. That's in addition to the heavy rain, snow, and brief periods of freezing rain and ice pellets in the Maritimes and Newfoundland. The most intense wind gusts could exceed 100 km/h on Monday in many communities and reach as high as 140-150 km/h in the Les Suêtes and Wreckhouse regions. Details and timing, below.

MONDAY: STRONG WINDS, HEAVY RAIN ACROSS THE REGION

New Brunswick could see brief periods of snow, ice pellets, and freezing rain on Monday. Snowfall amounts will be quite substantial in extreme northern areas of the province, where 20-30 cm is expected.

Rainfall warnings are widespread in Nova Scotia and New Brunswick, where 20-40 mm of rain could occur. “In addition, higher than normal water levels and rough pounding surf are possible at high tide Monday morning along the Atlantic Coast from Yarmouth to Canso. Heavy downpours can cause flash floods and water pooling on roads,” warns Environment Canada.

In Newfoundland, the system will begin to spread snow and ice pellets onto the western coast by the pre-dawn hours Monday, spreading east through the morning. Precipitation will switch to rain in the afternoon from west to east, with the heaviest rainfall along the Burgeo shores.

The most impactful part of the storm will be the winds, which may be damaging as they trail behind the system as it passes through and exits the region. Power outages will be a possibility in many areas along with heightened storm surges and high tides for the Atlantic shorelines.

Gusts could reach 100 km/h in much of Nova Scotia and Prince Edward Island, peaking early Monday morning and remaining strong until the evening hours, when they will start to subside. Wind warnings are in place including the Les Suêtes region, where gusts could hit 140 km/h.

The winds will pick up Monday morning in Newfoundland, reaching their peak in the afternoon and evening as they spread east. They will be slightly higher than in the Maritimes, with peak gusts of 120 km/h not out of the question for coastal areas. The Wreckhouse region may even see gusts reach 150 km/h.

The rain will depart the Maritimes by Monday evening, while Newfoundland will see sea-effect snow behind the system continue into Tuesday morning.
