WINNIPEG – WEATHER – There are Thunderstorm Watches out across southern Manitoba.
Severe thunderstorm watch in effect for:
- City of Winnipeg
Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing strong wind gusts, damaging hail and heavy rain.
A deepening low pressure system currently over northern Montana will track into southern Saskatchewan this afternoon. Warm, humid air is streaming rapidly northward ahead of this system and will set the stage for strong thunderstorm development over southeast Saskatchewan and southern Manitoba late this afternoon and tonight. Severe supercell thunderstorms are expected to develop over southeast Saskatchewan late this afternoon and move into southern Manitoba this evening and transition over to a line of storms in the Red River Valley this evening. There is strong shear to the atmosphere today with southeast winds at the surface and southwest winds aloft so there is a tornado risk especially over southwest Manitoba late this afternoon as storms start to develop.
Very large hail can damage property, break windows, dent vehicles and cause serious injury. Remember, severe thunderstorms can produce tornadoes. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
Severe thunderstorm watches are issued when atmospheric conditions are favourable for the development of thunderstorms that could produce one or more of the following: large hail, damaging winds, torrential rainfall.
