Part of Highway 40 in Kananaskis Country closed Sunday due to a mud slide.

According to a 511 Alberta advisory issued around 8:30 a.m. MT Sunday, a washout on the highway closed it to all traffic between the Mount Lipsett and Mist Creek day-use areas. That section of Highway 40 is roughly 130 kilometres southeast of Banff, Alta.

RCMP said on Sunday they expect the road to be closed for two days.

Sunday morning's advisory was an update to a previous advisory issued around 10 p.m. Saturday.

At that time, 511 Alberta said the highway between Elbow Lake and Junction south of Kananaskis Village was closed due to the mudslide.

A mudslide was also reported on Highway 1, west of Banff. 511 Alberta said the weather event brought debris onto the highway, causing delays east of Redearth Creek.

Environment Canada says more rain, with the risk of a thunderstorm, is in Sunday's forecast for Kananaskis Village.
