Snowy weather has led to some traffic tie-ups in parts of Saskatchewan.

In Regina police were advising motorists be cautious on the Ring Road where conditions were reported to be icy in spots. According to police, there were 17 crashes — none with injuries — reported in the city between 6 a.m. and 4 p.m. Friday.

West of Regina, around Lumsden, a four-vehicle crash on Highway 11 was affecting traffic in the area. There was also a crash on the same highway south of Craik.

Police were also dealing with a crash involving two semi-trailers on Highway 2 north of Moose Jaw.

The weather outlook in Saskatchewan includes lots of blowing snow, the return of colder temperatures and warnings for drivers to stay off certain highways.

By mid-afternoon Friday travel was not recommended on many roads in southern Saskatchewan, due mainly to blowing snow.

Conditions were changing quickly and motorists were being advised to check the Highway Hotline before heading out.

Environment Canada had issued winter storm warnings on dozens of communities, including, Regina, Moose Jaw, Yorkton and Swift Current.

A storm system near Weyburn was expected to dump snow on a wide section of southern Saskatchewan.

The greatest snowfall is expected over the eastern part of the province where 10 to 15 centimetres is expected near the Manitoba border.

Winds gusting to between 60 and 70 kilometres per hour are expected.

The blowing snow is expected to taper off in the evening, but then temperatures will start to drop, Environment Canada says.

The weather service also issued wind chill warnings for communities in Saskatchewan's north.
