An intense winter storm will move across New England Sunday, then the Gulf of St. Lawrence on Monday. It will especially affect the Gaspé Peninsula, bringing significant snowfall amounts and generating very strong to high northeast winds that will cause widespread blowing snow. The storm is expected to begin Sunday morning and continue through Tuesday with total snowfall accumulations between 30 and 60 centimeters. Travel is expected to be hazardous due to reduced visibility in some locations. Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Winter storm watches are issued when multiple types of severe winter weather are expected to occur together.

Statements

10:47 AM AST Friday 18 January 2019 Special weather statement in effect for (areas in grey)


Winter storm expected to bring major impacts to the region Sunday and into Monday. A low pressure system will approach the region from the southwest on Sunday and track across the Gulf of St. Lawrence early Monday as a large winter storm. All indications show a major snowfall event for areas north of the track of the low, a major rainfall event south of the track of the low, and significant amounts of snow, rain and an extended period of freezing rain near the track of the low. The precipitation will be accompanied by very strong east to northeast winds ahead of the low's track, shifting to very strong southerly winds south of its track. Current indications suggest that the storm will track through the Bay of Fundy Sunday evening and then into the Gulf of St. Lawrence overnight. This track could give snowfall amounts of 20-30 cm and rainfall amounts of 30-40 mm. It should be noted that even a slight shift in its forecast track will have major effects on the type and amount of precipitation received.
