WATCH BELOW: THIS WEEK'S ACTIVE STORM TRACK THROUGH ATLANTIC CANADA

A new low, tapping somewhat into tropical moisture from Storm Sebastien, began having some impact on the Atlantic Region later Wednesday, though with Newfoundland seeing most of the brunt.

Set to begin impacting Newfoundland through the overnight, it will intensify through Thursday morning to bring a mixed bag of rain and snow to the island.

The heaviest snow will be through central portions of the island, with negligible amounts for the west coast and none for the Avalon.

It's the eastern half of the island which is set to see the heaviest downpours, though most of Newfoundland will get some rainfall.

In the Maritimes, rain will be ending by Thursday morning, lingering longest in Cape Breton Island.

Gusty conditions will impact Newfoundland through Thursday, with 50-70 km/h gusts, easing by Friday.

STORMS KEEP COMING

"By Friday, attention will then turn to the west, as the third system moves in from the Great Lakes," says Weather Network meteorologist Kevin MacKay. "This Colorado low will have a northerly track, which keeps the cold air and heavier snow along and north of the St. Lawrence, with rain spreading across areas to the south once again."

This also means it will have a greater ability to pull arctic air southward behind it, resulting in some mixing and cooler temps across Atlantic Canada for the weekend.

Yet another significant system is expected by Sunday and Monday for the region, but the track of that fourth system is still highly uncertain at this time.
