After a spring-like hiatus, winter is expected to return to the island later today with a storm watch for western Newfoundland and a snowfall warning for the southwest coast.
Environment Canada has issued a winter storm watch for the Bay St. George, Corner Brook and vicinity, Deer Lake and Humber Valley and the Green Bay-White Bay areas.
Total snowfall accumulations of 10 to 15 centimetres are expected in these areas tonight and Sunday morning. However, amounts may possibly exceed 15 centimetres.
Environment Canada said people should be on alert for the potential development of dangerous winter weather conditions in these regions.
A snowfall warning is in place for the Channel-Port aux Basques area and the Burgeo-Ramea area, with total snowfall accumulations of 15 to 20 centimetres expected tonight and Sunday morning.
The snow is expected to begin falling in the southwestern region this evening and turn to blowing snow overnight as wind gusts reach up to 60 kilometres per hour overnight.
The snow is expected to begin in the Bay St. George and Corner Brook areas after midnight and winds will reach gusts of 50 kilometres in the areas under the winter storm watch.
A low pressure system south of Cape Cod will move northeastward and intensify today then lie south of Cape Breton Island overnight. The low is forecast to cross southeastern Newfoundland Sunday morning then continue out to sea.
Snow, at times heavy, will develop over southwestern Newfoundland this evening and spread northeastward throughout the night. The heaviest snow is expected from the southwest coast to the northeast coast.
