Severe Thunderstorm Watch

Issued at 15:17 Tuesday 19 September 2017

Conditions are favourable for the development of very dangerous thunderstorms that may be capable of producing damaging wind gusts and flooding rain.

A low pressure system now in Saskatchewan will slowly track through southern Manitoba tonight. This weather system will continue to spread rain through southern Manitoba tonight with widespread rainfall amounts of 20 to 30 mm.

There is the likelihood that intense embedded thunderstorms will accompany this rain. These severe thunderstorms may bring rainfall totals over 50 mm as well as locally strong wind gusts.

The potential for these intense rainfalls will begin in the Westman area and then move through the Red River Valley and interlake areas this evening. These severe thunderstorms may persist past midnight as they continue towards the Ontario boundary.


Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Heavy downpours are likely to cause flash floods and water pooling on roads.

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.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #MBStorm.
