Heavy Snow, Strong Wind, and Rain Heading Toward Atlantic Canada

Posted by Kyle Brookings on Tuesday, November 13, 2018

An area of low pressure currently over the U.S. Northeast will bring heavy snow, strong winds, rain, and some mixed precipitation to Atlantic Canada over the next few days.

Snow will develop across most areas of New Brunswick this morning and then change to rain this afternoon. Snowfall amounts will range from 10 to 20 cm in the north and 5 to 10 cm over portions of the south. Precipitation is expected to end tonight with rainfall amounts of 20 to 35 mm likely in the south. Additionally, very strong wind will develop.

On Prince Edward Island wind is the main threat with winds gusting to 90 km/h expected on Wednesday.

Strong wind is expected across most of Nova Scotia with gusts to 100 km/h expected today and tonight. Les Suêtes winds gusting to 120 km/h are expected tonight. Periods of snow will develop Wednesday morning and amounts possibly exceeding 15 cm over the Highlands are forecast by Wednesday evening. Further snowfall accumulation is expected Wednesday night into Thursday. Elsewhere across the province, the system will give snow and rain but significant accumulations are not expected.

The low moves into Newfoundland overnight. Heavy snow is expected for central and western Newfoundland before a messy mix to rain. On the Avalon there will be a rain-snow mix followed by a transition to rain. Strong southeasterly winds with gusts up to 120 km/h are expected to develop in the Wreckhouse area overnight tonight. Snow will change to a brief period of rain before changing back to snow at times heavy by Wednesday afternoon on the west coast. Accumulations of 15 cm to 20 cm are possible combined with very strong wind. In central Newfoundland 10 to 15 cm is expected by Wednesday morning. For central and eastern Newfoundland wind gusts to 100 km/h are expected.
