An approaching nor’easter is expected to bring strong winds, heavy rain, and a significant amount of snow to parts of the Maritimes, with the most severe impacts anticipated from Tuesday evening through Wednesday afternoon.
While there is still some uncertainty regarding the storm’s exact path, residents should be prepared for potential power outages and disruptions to travel, such as ferry and bridge closures, as wind gusts could reach speeds of 70 to 90 kilometers per hour.
Environment Canada has issued yellow warnings for several regions in Nova Scotia, including northern Cape Breton, Yarmouth, Shelburne, Annapolis, Kings, Hants, Colchester, Pictou, Antigonish, and Cumberland counties. These warnings indicate the possibility of hazardous weather conditions that could lead to damage, disruptions, or health issues.
The risk of power outages is heightened by the heavy wet snow expected to fall in inland and higher-terrain areas of Nova Scotia, as well as Prince Edward Island and southern New Brunswick. Snowfall amounts are projected to range from 15 to 30 centimeters, with localized heavier accumulations likely in areas like the Cobequid Pass and Mount Thom.
The most challenging forecast is for the Annapolis Valley, Truro, and eastern P.E.I., where slight temperature variations could significantly impact snowfall amounts. Variability in snowfall is expected across this region, influenced by factors such as elevation and proximity to the coast.
Coastal regions of Nova Scotia are likely to experience mainly rain, though some snow may mix in on Tuesday evening and Wednesday morning. The transition between rain and snow accumulation will depend on elevation and distance from the coast.
Areas along the Bay of Fundy and near the Northumberland Strait may also see a mix of rain and snow overnight into Wednesday.
Environment Canada has issued yellow rainfall warnings for Shelburne and Yarmouth counties, along with yellow snowfall warnings for Annapolis, Antigonish, Colchester, Cumberland, Hants, Kings, and Pictou counties. Under the new weather warning system, yellow alerts signify potentially hazardous conditions that could affect travel and lead to delays or cancellations.
The storm is expected to begin affecting the region on Tuesday afternoon, with light snow for most areas and rain along the Atlantic coastline. As the storm center moves over the province on Tuesday night, heavier snowfall rates are anticipated. Coastal regions will likely see a mix of rain and snow, with some areas transitioning entirely to rain.
Wednesday morning will bring continued snow and rain, resulting in a messy commute for many residents. Colder air wrapping into the storm could lead to snow mixing in along the Atlantic coastline. Winds are forecasted to strengthen on Tuesday night, with gusts of 70 to 80 km/h expected for Nova Scotia, P.E.I., and southeastern New Brunswick. Coastal areas may experience gusts up to 90 km/h, especially in eastern P.E.I. and Cape Breton. Winds are forecasted to diminish from west to east by Wednesday evening.
