Flood and outage risk as heavy rain, winds blast through Atlantic Canada
A series of systems will pull in significant subtropical moisture, bringing heavy rainfall and powerful wind gusts over 100 km/h, with Newfoundland experiencing the strongest impacts
Atlantic Canada is set to remain active this week, with two low pressure systems bringing widespread rain and some snow by mid and late week. Substantial moisture from the subtropics will fuel these systems, the first arriving Thursday and the second on Friday. Extensive snowmelt could lead to localized flooding in some areas.

Looking ahead, a series of storms is expected to continue into next week, with colder temperatures forecast, especially across the Maritimes. This shift increases the potential for impactful winter storms in the region. You'll want to stay updated and check back for forecast details as conditions develop.
Localized flood threat with heavy rain and snowmelt
Widespread steady rain will move through the Maritimes Thursday morning into the afternoon before clearing by early evening. Northern New Brunswick, including areas such as Edmundston and Campbellton, is forecast to see up to 5 cm of snow, while most other areas will remain mild enough for rainfall.
Rain will also reach Newfoundland by late Thursday morning, continuing through the day. Rainfall from this system will be less intense for Newfoundland compared to the next round.
A brief overnight break is expected before heavier rain arrives again by daybreak Friday. The heaviest rainfall will impact Newfoundland and possibly eastern Nova Scotia.
Overall, Nova Scotia, southern New Brunswick, PEI, and Newfoundland are forecast to receive 15-25 mm, while southern and eastern Newfoundland could see totals between 50-80 mm.
Power outage potential with another round of strong winds
Wind gusts for Thursday will range from 30-50 km/h in the Maritimes and 40-80 km/h in Newfoundland. Friday looks windier, particularly for eastern Newfoundland, where gusts could exceed 110 km/h by the afternoon and evening. Elsewhere, wind gusts will increase to 50-80 km/h on Friday.
Localized flooding is possible due to rain and snowmelt, along with the risk of power outages in areas like the Avalon Peninsula.
A series of storms is expected to continue into next week, with temperatures trending colder, particularly in the Maritimes. This shift increases the potential for a few high-impact winter storms in the region.
