THUNDER BAY – WEATHER – From Manitoba to Northeastern Ontario, winter weather conditions range from blizzard warnings on the western side of the Colorado Clipper that is churning northerly, to winter storm warnings on the eastern side of the weather system.

In Manitoba, blizzard conditions are impacting the Brandon region.

In terms of travel conditions, James Richardson International Airport in Winnipeg is already seeing some flights cancelled. As the storm’s reach expands, it is possible that it could also impact Toronto Pearson as there is freezing rain in the forecast for Monday.

Blizzard warning in effect for:

  • City of Brandon
  • Mun. of Glenboro-South Cypress incl. Treesbank
  • Mun. of Norfolk Treherne
  • Mun. of North Cypress-Langford incl. Neepawa and Carberry
  • Mun. of North Norfolk incl. MacGregor Sydney and Austin
  • Mun. of Oakland-Wawanesa incl. Carroll
  • R.M. of Cornwallis west of Shilo incl. Chater
  • R.M. of Elton incl. Forrest
  • R.M. of Victoria incl. Holland and Cypress River

Blizzard conditions with poor visibility in snow and blowing snow are expected or occurring.

A major storm system will significantly disrupt holiday plans for all of southern Manitoba and southeastern Saskatchewan.

A Colorado low moving northeastward continues to develop and intensify. Radar imagery at 3 pm local time shows the main area of snow approaching the international border of North Dakota. Over the next few hours that area will continue to push northwards and intensify. Snowfall accumulation rates in this area are high; conditions will deteriorate rapidly. Current data indicates that generally 20 to 30 cm of snow will fall by Monday morning with some areas near the U.S. Border potentially seeing 40 to 50 cm.

Areas that will see the strongest northerly winds such as in the Red River valley and western Manitoba combining with the fresh snow will also see blizzard conditions. These conditions should gradually improve from west to east starting Monday afternoon as this system continues to track eastward away from the region with blowing snow and reduced visibilities persisting until the winds die down.

Travel is expected to be hazardous due to reduced visibility. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.

Blizzard warnings are issued when widespread reduced visibilities of 400 metres or less are expected for at least 4 hours.

In Toronto, there is a special weather statement in effect.

Special weather statement in effect for:
