An intense disturbance tracking across the United States will bring strong northerly winds and snowfall to the southeastern Manitoba, Environment Canada warns this afternoon.
The late afternoon weather warning states motorists can expect poor visibility in snow and blowing snow in some locations.
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.
Snowfall associated with this disturbance will enter the region tonight and continue on Thursday before tapering off late Thursday morning or early Thursday afternoon. The highest snowfall amounts are expected over extreme southeastern Manitoba and will diminish rapidly as one heads northwestward into the northern Red River Valley and southwestern Manitoba. As a result, total snowfall amounts over the blowing snow advisory area will likely vary widely with some regions seeing trace amounts while others may see amounts closer to 10 cm.
In addition to the snow, intense northerly winds are expected to develop overnight and continue on Thursday. Winds gusting at times to 80 km/h will combine with the falling snow to produce widespread blowing snow resulting in near blizzard conditions in areas where the snowfall amounts accumulate. As the precipitation exits the region visibilities are expected to improve. However, the strong winds will likely continue to produce heavy drifting snow into Thursday.
Travel is expected to be hazardous due to reduced visibility in some locations. If visibility is reduced while driving, turn on your lights and maintain a safe following distance.
