Update on the Incoming System to Atlantic Canada


An area of low pressure will begin to impact the Maritimes overnight tonight.


Quebec

Snow is expected to begin Tuesday afternoon across southern and eastern Quebec. Precipitation will largely remain as snow. The Lower North Shore could see some mixed precipitation on Wednesday night. Winds will also be gusty.


Snowfall amounts between 20 and 40 centimetres are expected. This heavy snow combined with strong winds will result in reduced visibility with blowing snow.


Maritimes

Snow will start in southern Nova Scotia before dawn. Snow will spread across all three Maritime provinces. Snow is expected to change to ice pellets and then rain. All of Nova Scotia, PEI, and eastern New Brunswick will change to rain. New Brunswick will see a snow to ice pellet mix. There will be strong winds.


Across central and western New Brunswick 15 to 30 cm of snow is expected. On Prince Edward Island the heaviest snow is expected in western areas where 25 to 30 cm is possible. For central and eastern Prince Edward Island 10 to 15 cm of snow is expected followed by 20 mm of rain.


Heavy rain and strong winds are expected across Nova Scotia. Between 50 and 70 mm of rain is expected for the eastern half of Nova Scotia combined with wind gusts to 100 km/h except 140 km/h in Les Suetes winds.


Conditions improve on Thursday. A much smaller low will bring some rain to the Fundy Coast.


Newfoundland

On Wednesday night snow will spread across most of Newfoundland before changing to ice pellets, freezing rain, and rain over the course of the day on Wednesday. There will be strong winds. Conditions improve on Wednesday night.


Snowfall amounts will vary widely across Newfoundland with only about 2 cm expected on the south coast and the Avalon to 20 to 30 cm over the Great Northern Peninsula and between 5 and 15 cm elsewhere.
