Snow is expected to spread across the island part of the province during the day Wednesday, in advance of a low-pressure system to track northeastward across Newfoundland Wednesday night and head out to sea Thursday.

According to Environment Canada, snow is expected to change to ice pellets and freezing rain to rain over eastern areas as temperatures rise, with some locations potentially receiving two to four hours of freezing rain before the changeover. 

Rainfall amounts with this system may reach 25 millimetres over southeastern parts of Newfoundland before tapering off Wednesday evening.

Environment Canada notes, however, there is some uncertainty regarding the exact track of the system, but latest indications suggest areas to the west of its track, including the west coast, and parts of central Newfoundland, may receive significant amounts of snowfall accumulation, with totals in excess of 15 centimetres. 

The snow will taper off Wednesday night into early Thursday as the low moves away.

In addition, a strong southwesterly flow will develop over eastern Newfoundland in the wake of this low late Wednesday night, with gusts potentially reaching warning criteria. Strong winds will then likely persist into Thursday morning before easing during the day.

This system may push higher than normal water levels onshore along the south coast and southern parts of the Avalon Peninsula Wednesday night.

Meantime, strong southwesterly winds gusting to 100 km/h are expected Tuesday night on the Northern Peninsula.

Winds are expected to be strongest over northern parts of the island where gusts are forecast to reach 100 km/h Tuesday evening. Winds will ease to below warning criteria later Tuesday night.
