Weather Warnings and Advisories Across Northwestern Ontario

Sault Ste. Marie:

Lake effect snow squalls continue today. Hazards: Locally heavy snowfall with additional accumulations near 20 cm. Peak snowfall rates of 2 to 5 cm per hour. Very poor visibility at times in heavy snow and blowing snow. Power outages possible due to the heavy wet nature of the snow. Timing: Continuing through this evening. Discussion: Lake effect snow squalls off Lake Superior will continue today as a low pressure system moves across Lake Superior, enhancing snowfall amounts. Snow squalls will then move south of the region this evening. Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Road closures are likely.

  • December 4: Snow with additional accumulations; high of 0°C and low of -7°C.
  • December 5: Windy and colder with 5-10 cm of snow; high of -4°C and low of -9°C.

  • December 4: Cloudy and increasingly windy with some snow; high of -4°C and low of -10°C.
  • December 5: Breezy in the morning; otherwise, cold with some clouds, then sunshine; high of -7°C and low of -12°C.

Prairies

Winnipeg, Manitoba:

Poor visibility in snow and blowing snow is expected or occurring in some locations. Reduced visibilities in blowing snow are expected at times throughout the Red River Valley today. Lake-effect flurries occurring concurrently with northerly winds gusting from 70 to 80 km/h will produce poor visibilities in blowing snow on Wednesday.

In the city of Winnipeg, this reduction in visibility will occur most often in open areas and in the vicinity of the Perimeter Highway. Winds will abate and visibilities will improve over the northern Red River Valley, including the city of Winnipeg, by Wednesday afternoon.

Improvement over the south is expected by Wednesday evening. Travel is expected to be hazardous due to reduced visibility in some locations. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop.

Ensure that shelter is provided for pets and outdoor animals. Blowing snow advisories are issued when winds are expected to create blowing snow giving poor visibility to 800 metres or less for at least 3 hours.

Wardrobe Suggestions

Across Canada, proper winter attire is critical to navigating these wintry conditions. In areas experiencing snow squalls or extreme cold, residents should wear layered clothing, heavy winter coats, insulated boots, hats, gloves, and scarves to prevent frostbite. In the Prairie provinces, strong winds and sub-zero temperatures necessitate wind-resistant gear. Residents in Atlantic Canada should also prepare for wet snow and rain, requiring waterproof outerwear.


Weather Trivia

Did you know that snow squalls, like those currently impacting Sault Ste. Marie and surrounding areas, are among the most localized and intense weather phenomena in Canada? These storms, fueled by lake effect, can produce snowfall rates of 2-5 cm per hour, creating drastic visibility changes within minutes. Meanwhile, Alert, Nunavut, holds the record as the northernmost permanently inhabited settlement on Earth, where December daylight lasts only a few minutes each day.
