Dangerous avalanche conditions are in place across much of Southern Alberta's mountain ranges and have led to a section of Highway 1 in eastern B.C.

Avalanche Canada's map shows very dangerous avalanche conditions in Kananaskis Country, including Banff National Park.

The area has a danger rating of 4, as do the mountainous regions to the north and south.

An overnight snowstorm is expected to worsen the conditions, heightening the risk of human-triggered avalanches.

Further to the west in B.C., similarly dangerous conditions in Glacier National Park and surrounding areas have led to closures, including the stretch of Highway 1 between Golden and Revelstoke being closed overnight.

⛔️ CLOSURE UPDATE #BCHwy1 - the highway is now closed in both directions between #RevelstokeBC and #GoldenBC due to high #avalanche danger. No detours are available.

No detours are available, and it's estimated to be reopened tomorrow (Feb. 29) afternoon.

K-Country area closures can be seen on the Parks Canada website.
