Precipitation will begin in southern areas during the wee-morning hours on Monday, steadily filling in over the Maritimes as the day progresses.
Periods of rain and snow will continue into Monday night before tapering off as the system moves on. Rain and snow will begin to move into Newfoundland through the latter half of Monday.

Portions of New Brunswick, P.E.I., and eastern Nova Scotia could see 5-10 cm of snow by Tuesday, with a light dusting possible anywhere else where rain changes to snow.
Forecasters are keeping an eye on the potential for another impactful storm to push into Eastern Canada by the middle of the week, which could bring an additional opportunity for wet snow across the region.
