Warnings

10:42 AM CDT Thursday 10 October 2019 Winter storm warning in effect for areas in red


Rain and snow has spread into southern Manitoba this morning, courtesy of an approaching Colorado low. As anticipated the rain/snow line has set up roughly along the Red River Valley, with western sections of the valley seeing snow and eastern sections seeing rain or a rain/snow mix. The weather is even sharply different across the city of Winnipeg, with significant snowfall accumulations in the west of the city and little in the east.

In the worst affected area...roughly from just west of Winnipeg to just east of Brandon...heavy, wet snow will continue throughout the day, accompanied by northerly winds gusting up to 70 km/h. Total accumulations by this evening in this area will range from 10-15 cm. Travelling will become increasingly difficult as the day wears on, with heavy, accumulating snow, strong winds and temperatures near zero resulting in treacherous conditions.

Periods of heavy snow will continue through Friday into Saturday. By Friday evening total snowfall accumulations of 30 to 50 cm are quite likely in this area.

In addition, very strong northerly winds are forecast for Friday, especially where winds blow onshore off the Manitoba Lakes. The extreme winds and heavy snowfall will persist into Saturday.

The combination of wind and wet snow may pose a problem with tree branches or power lines. Consider postponing non-essential travel until conditions improve. Prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow.
