Winter storm warning for
Grande Prairie – Beaverlodge – Valleyview upgraded from Winter storm watch

Winter storm with heavy snow starting Sunday.

This is a warning that dangerous winter weather conditions are imminent or occurring in these regions. Monitor weather conditions…Listen for updated statements.

A low pressure system will move through Alberta today and bring patches of freezing rain from the Grande Prairie area towards Whitecourt and Rocky Mountain House this morning. The area of freezing rain will move slowly eastward this morning and early this afternoon. Freezing rain warnings may have to be expanded as the precipitation develops.

An intense winter storm is forecast to develop and move into Alberta on Sunday. Associated with this system, snow at times heavy will spread into Northwestern Alberta early Sunday morning. As the storm winds up, it will track southeastward into Central Alberta by Sunday evening and continue into Southern Alberta overnight. We expect a fairly wide swath with snowfall amounts of 15 to 25 cm while some areas could see more than 30 cm.

In the wake of the storm system on Monday, strong northerly winds will develop and usher in cold Arctic air. Winds gusting above 60 km/h will produce extensive blowing snow over Central and Southern Alberta. Over open areas including Major Highways, visibilities will deteriorate to blizzard conditions and travel would not be advised.

As the Arctic high builds into the province on Tuesday, winds will diminish gradually from the north and temperatures will drop to near minus twenty.

At this time there is still some uncertainty with the track of the storm system and the amount of heavy snow and blowing snow. As the arrival of the storm nears and the situation becomes clearer, warnings will be issued as necessary and watches may be expanded.

A winter storm watch is an alert of the potential development of severe winter weather. Persons in or near these areas should be prepared for developing adverse weather conditions and should listen for updated watches and possible warnings.
