An upper low pressure system over southern Alberta is producing thunderstorms this evening which may become severe. The thunderstorms will change to heavy rain overnight and continue on Thursday. Total rainfall amounts of 50 to 70 mm are expected by Thursday evening.

Heavy downpours can cause flash floods and water pooling on roads. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop. Avoid driving through water on roads. Even shallow, fast-moving water across a road can sweep a vehicle or a person away.

Stay up to date with the latest weather updates.

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.
