Colorado Low impacting Manitoba and Ontario, eyes Quebec & Atlantic Canada

A Colorado Low is impacting parts of Manitoba and Ontario and will impact Quebec and eventually Atlantic Canada.

Southern Manitoba

Over extreme southern sections of the province, snowfall amounts of 20 to 30 cm are expected.

Snowfall totals will decrease to the west and northwest, with the Red River Valley seeing 10 to 15 cm of snow and western Manitoba looking at storm totals of 5 to 10 cm.


Snow is expected across most of Northern Ontario today. 20 to 40 cm is expected for areas west of Thunder Bay and 10 to 15 is expected east of Thunder Bay to the Quebec border and south to Sudbury. Freezing rain or ice pellets are possible in northeastern Ontario.

From near Sudbury to about Peterborough rainfall amounts of 30 to 60 mm is possible. There is a risk of freezing rain in areas where temperatures are near zero.

30 to 40 mm of rain is expected for the remainder of southern Ontario along with the risk of severe thunderstorms.


Across southwestern Quebec, widespread freezing rain is expected tonight and Thursday.

Amounts will vary from at little as 2 mm to as much as 20 m of ice accumulation.

Power outages are a possibility and travel will be difficult.

Atlantic Canada

Wednesday night and Thursday morning, freezing rain is expected across southern and eastern New Brunswick and parts of northern Mainland Nova Scotia.

On Thursday night and Friday, a similar event is expected in Newfoundland.

As this is still a couple of days out, it remains too early to provide precipitation amounts.

This storm has the potential to cause significant travel disruptions.
