RCMP in southern Alberta are dealing with four semi tractor-trailer rollovers on Highway 22 and say winds in the area are excessive.

The rollovers are on the highway between Maycroft and Highway 3 and police say truck drivers should avoid the area until the winds die down.

The winds are so strong that RCMP officers are having a hard time staying on their feet to investigate the crashes and assist the truckers.

The occupants of the trucks have reported only minor injuries so far.

Environment Canada has issued a wind warning for the Crowsnest Pass, Pincher Creek and Waterton Lakes areas and says gusts could exceed 100 km/h by noon.

Conditions are expected to improve by Tuesday afternoon.
