Update: Heavy Freezing Rain Risk Extended Southeast, Eastern Newfoundland Impacts Increased

After reviewing the latest model data, we've updated our freezing rain forecast to reflect a southeast shift in the heaviest precipitation and to include additional freezing rain expected for Monday morning.

Corner Brook and Deer Lake will still get significant ice accretion, but it is a bit less than originally expected. From Gander, through Terra Nova, to Clarenville can now expect to impacted more by the storm.

Typically, 10mm of ice accretion from freezing rain is enough to damage trees and power lines. Beyond that, with 25+mm, we could be looking at extensive damage. Wind gusts appear to remain light through the day tomorrow and into Sunday morning, but will pick up by Sunday afternoon. Gusts will be in the 40-50km/h range and this could trigger additional damage to trees and power lines.

We've already begun to see some light freezing rain around Port aux Basques with the transition from snow to rain and in the early morning hours, there will be a pocket hitting the Corner Brook and Deer Lake area. It will spread south and east through the morning and by mid-afternoon, the heaviest freezing rain will start and it will last into overnight. The freezing rain will continue throughout the day Sunday and into Monday morning, but it will be focused over Central and Eastern Newfoundland, giving Western Newfoundland a reprieve.
