A low pressure system will develop along the American Seaboard and intensify as it approaches this province mid-week.
The system is currently forecast to track just east of the Avalon Peninsula early Thursday then move out to sea later Thursday, Environment Canada said in its statement.
At this point, heavy rain is expected over southeastern Newfoundland including the Avalon Peninsula Wednesday night into early Thursday.
Over central regions of the Island, as well as the northeast and east coasts, rain showers Wednesday will give way to steadier rain before changing to snow, at times heavy, Wednesday evening, the national weather forecaster said in its statement.
Accumulations could be significant and are likely to be quite variable depending on elevation and proximity to the coast, Environment Canada said. Conditions should improve throughout the day Thursday.
