Statements

3:30 PM CST Thursday 20 December 2018 Special weather statement in effect for (areas in grey)


A low pressure system will bring a risk of freezing rain to portions of southern Saskatchewan and western Manitoba tonight into Friday.

An area of freezing rain is forecast to develop over central Alberta this evening. This freezing rain will then spread from west-central Saskatchewan to southeastern Saskatchewan and western Manitoba overnight through Friday. Regina, as well as many major highways including the Yellowhead, Highway 11, and the Trans-Canada Highway between Regina and Brandon, look to be at risk for seeing some amounts of freezing rain overnight into Friday.

There is still some uncertainty in the exact track of this band of freezing rain, but it should become apparent as the system develops in Alberta today. More details on the likelihood and timing of the freezing rain can be found in local forecasts. The public is advised to watch for updated forecasts and/or alerts issued by Environment and Climate Change Canada later today.
