HALIFAX -- On Sunday, a Colorado low is forecast to reach the southwest of Nova Scotia before moving northeast along the Atlantic coastline and into southern Newfoundland. A fair bit of snow is expected for much of the Maritimes, along with some high winds.

The snow begins in southwestern New Brunswick and Nova Scotia just after midnight Saturday into Sunday. Snow will fall across the region Sunday morning through evening before easing to flurries Sunday night.

forecast timeline

Snow develops through Sunday morning for much of the Maritimes.

At this time, much of southern New Brunswick, P.E.I., and Nova Scotia look to pick up 15 to 25 cm of snow. Snowfall amounts will taper lower for the South Shore of Nova Scotia due to ice pellets and rain mixing in. Snowfall amounts will also taper lower into northern New Brunswick due to being on the outskirts of the system.

snowfall outlook

15 to 25 cm looks likely in the heaviest snow. Amounts taper lower for the South Shore of Nova Scotia and northern areas of New Brunswick.

East and southeast winds will increase through the day on Sunday, peaking with gusts of 50 to 80 km/h for Nova Scotia, 40 to 70 km/h for P.E.I., and 30 to 50 km/h for New Brunswick by afternoon and evening. The wind will turn to the northwest Sunday night and diminish into Monday morning. The wind will combine with the snowfall to reduce visibility and create drifts.

gust forecast

Increasing east and southeast winds will drive areas of blowing and drifting snow on Sunday.

Travel will likely be the biggest impact. There will be winter road conditions for a large area of the Maritimes on Sunday and services such as airports, ferries, and bridges should be monitored for disruption.

The system is still nearly 48 hours out in the forecast and there is time to see significant change to how much snow is expected for specific communities. It is highly recommended that you check in on your forecast again Saturday, no matter the source.
