Winter Weather Impacting Manitoba
Special weather statement in effect for:
- City of Winnipeg
Southern Manitoba remains in a very active storm track as another Colorado low will be developing tonight and moving northeastward. Current indications have this storm system tracking a little further south then the one last week, so the heaviest snow should remain south of the international border. Areas along the Trans Canada highway corridor will receive 5 to 10 cm with snowfall amounts increasing as you move further south. Areas near the international border over southeastern areas of Manitoba should expect 10 to 20 cm of snow by noon on Tuesday.
Light snow is expected to develop from the southwest late tonight and periods of light snow expected through the day on Monday. The heaviest snow should occur from Monday evening into the early morning hours of Tuesday. The snow should taper off from west to east on Tuesday. In addition to the snow, strong northerly winds gusting to 50 and 60 km/h will develop Monday evening especially over the southern Red River valley. This may produce poor visibilities in snow and blowing Monday evening and Tuesday morning.
Weather warnings may be issued tonight or tomorrow as the system continues to develop.
