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

A low pressure system in Eastern Saskatchewan is creating an unseasonably hot and humid air mass over Southeastern Saskatchewan and Southern Manitoba and will lead to scattered thunderstorm development over the region this afternoon and evening. Some of these thunderstorms could become severe.

Thunderstorms are expected to develop over Eastern Saskatchewan and Southwestern Manitoba this afternoon and gradually progress eastwards along an advancing cold front. The threat for severe weather will progress into Eastern Manitoba this evening which may require an expansion of the watch area.

The main threats with these thunderstorms will be heavy rainfall in excess of 50 millimeters, nickel to quarter-sized hail, and gusty winds.

A few funnel clouds cannot be ruled out over Eastern Saskatchewan, as well.

Very large hail can damage property, break windows, dent vehicles and cause serious injury. Very strong wind gusts can damage buildings, down trees and blow large vehicles off the road. Remember, severe thunderstorms can produce tornadoes. Heavy downpours can cause flash floods and water pooling on roads.

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