Flood fears remain high across parts of the East Coast after the extreme deluges that washed out multiple roads across parts of Nova Scotia and Newfoundland earlier this week. Now, as we head into the weekend, more moisture is set to push into the region, though much less than the already excessive amounts. Heavy snow has also prompted warnings across parts of New Brunswick, with up to 20 cm possible in the hardest hit areas through Saturday. More on the timing and impacts, below.
FRIDAY INTO THE WEEKEND: MESSY MIX OF RAIN, FREEZING RAIN AND HEAVY SNOW
There'll be somewhat of a reprieve on Friday to allow for a bit more drying out before the next system begins to approach the Atlantic region, with its effects ramping up overnight into Saturday for the Maritimes, and Saturday into Sunday for Newfoundland.
This time, the heaviest rainfall totals look to be in central, eastern and northern New Brunswick, along with southern Newfoundland, where around 20-30 mm of rain is possible.
Though amounts in eastern Nova Scotia only range from 10-20 mm, it will come at a time when the hardest-hit areas will still be somewhat waterlogged. With limited ability to absorb the new showers, the runoff may lead to localized flooding in some areas.
This system will also feature some snow as cold temperatures descend Saturday. While amounts will be limited for most places, the northwest of New Brunswick could notch as much as 10-20 cm. A period of freezing rain will also spread across the region later Friday before the precipitation changes to straight snow. Snowfall warnings are in effect.
"Be prepared to adjust your driving with changing winter road conditions," says Environment and Climate Change Canada in the warning. "Rapidly accumulating snow could make travel difficult over some locations."
Across the gulf, western Newfoundland may see some sea-effect flurries Saturday, ending by Sunday morning.
BEYOND: STUBBORN STORM PARADE PERSISTS
On the heels of this system, forecasters are keeping an eye on the next low pressure system that looks to develop off the U.S. East Coast and rapidly intensify as it tracks into Atlantic Canada early next week.
This will bring widespread rain and windy conditions to the region, with temperatures remaining very mild to the east of the storm track and daytime highs into the lower teens possible for eastern Newfoundland.
"However, a swath of significant snow is expected to the west of the storm track and for parts of New Brunswick, eastern Quebec and into Labrador," warns Doug Gillham, a meteorologist at The Weather Network.
Conditions will then turn colder as the storm departs. Another system is possible by mid to late week.
