After a night of nasty storms, streets were clogged with snow, mail delivery was cancelled and school buses weren't running in many Saskatchewan communities.

Saskatchewan was digging itself out on Friday, although many communities were struggling with continued blustery conditions.

According to Environment Canada, 15 to 25 centimetres of snow fell during the storm. Another five centimetres was expected to fall in some areas, before the end of the day Friday.

The Trans-Canada Highway was closed all around Moose Jaw early Friday morning, but it has reopened.

Starting at around 3 a.m. CST, the highways ministry closed the Trans-Canada, also known as Highway 1, all the way from Belle Plaine in the east to Mortlach in the west. It reopened the section around 9 a.m.

Before the sun came up, some provincial routes north of Moose Jaw and around Swift Current were closed. Throughout the day, travel was not recommended over a wide area from the Alberta border to east of Regina.

With conditions changing rapidly people were being advised to check the Highway Hotline before heading out.

No mail

Meanwhile, poor travel conditions and road closures led Canada Post to cancel letter carrier delivery in Moose Jaw and Swift Current.

The postal service said once the weather and travel conditions improve, it will reassess the situation.

Some flights out of Regina were cancelled or delayed.

In Regina, both the public and Catholic school boards said the buses had been cancelled, but the schools were still open. The French school board cancelled bus service to École Monseigneur de Laval.

Many rural school buses were not running. There were a few "snow days" around the province, although schools in Gravelbourg were closed for the day.

Further north, the storm didn't hit as hard. In Saskatoon, there were normal winter driving conditions reported by highway officials in the morning.

The additional snow will have some communities facing a total of 30 centimetres.

"It's going to be a big cleanup day to be sure," CBC Saskatchewan weather consultant Wayne Miskolczi said.
