Winter storm watch for Saskatoon and west central Sask.

Watch out for blizzard conditions to start the weekend as Environment Canada has issued a winter storm watch for parts of west and central Saskatchewan, including Saskatoon.

A winter storm developing in Alberta is expected to move into Saskatchewan Friday evening and last until Saturday night.

Lloydminster is already under a storm warning, while the watch extends from the Battlefords south to the Leader-Gull Lake area and west, covering all areas from Rosetown and Biggar to Martensville and Warman.

Weather conditions change fast, so check the Environment Canada website for updates.

The weather agency is forecasting total snowfall amounts to be between 10 to 20 centimetres or four to eight inches.

Snowfall combined with strong winds up to 40 to 50 kilometres per hour could create significant visibility problems on highways Friday and Saturday.

Anyone planning highway travel on Friday or Saturday might want to check the Highway Hotline for updated conditions before heading out.
