Intense low to push across Newfoundland

A disorganized area of low pressure will push across Newfoundland and parts of Labrador beginning this afternoon.

Snow will spread across western and central Newfoundland this afternoon while rain is expected for the south coast and the Avalon Peninsula.

Precipitation will continue overnight and into Monday. For southeastern Labrador 10 to 25 cm of snow is likely. Across western Newfoundland, central, and parts of the south coast, east to about Harbour Breton, 10 to 25 cm of snow is expected.

Across the Avalon, Burin, and Bonavista Peninsulas, rain will be the dominant form of precipitation. Rainfall amounts will range from 10 to 20 mm.

On Monday some areas will see the precipitation wind down in the afternoon but very strong winds are expected behind the low. For southeastern Labrador wind gusts to 100 km/h are expected. The Northern Peninsula through to the Corner Brook area will see wind gusts to 80 km/h, in Gander wind gusts to 90 km/h are expected, and for the Avalon Peninsula wind gusts to 110 km/h are expected. Power outages are possible.

In Nova Scotia this is a winter storm warning in effect for Inverness County - Mabou and north and Victoria County. 35 cm of snow is expected along winth wind gusts to 90 km/h this evening through Monday afternoon.

Marine Atlantic has cancelled departures for this evening and anticipates a potential impact to departures on Monday morning.
