Rainfall Warning Issued For Southwestern Alberta, Calgary

Environment Canada has issued a rainfall warning for much of southwest Alberta, with the possibility of localized flooding.

Kananaskis, Canmore, Crowsnest Pass, Pincher Creek, Waterton Lakes National Park and Fort Macleod have all been issued rainfall warnings Monday morning.

According to Environment Canada, a low pressure system moving into the northern United States will bring significant rainfall to the area.

The heaviest rainfall is expected Monday afternoon, with 50 to 80 millimetres of precipitation expected to fall in some areas.

Alberta Environment issued a flood alert shortly after noon Monday for the Wallaceville Area of High River, Crowsnest River and Willow Creek.

The provincial agency has also issued high stream flow advisories for streams and rivers in the Bow, Oldman, Milk and South Saskatchewan River basins.

Additionally, the City of Calgary warns the Calgary area is expecting five to 10 millimetres of rain between Monday afternoon and Wednesday, which will cause the Elbow River to receive between 30 millimetres of rain Monday and an additional 15 millimetres Tuesday.

The city says this is expected to increase the flow rate into the Glenmore Reservoir to 120 to 170 cubic metres per second by Tuesday.

The seasonal norm for the Elbow River above the Glenmore Reservoir, says the city, is 30 cubic metres per second. During last year’s flood, the Elbow River above the reservoir peaked at 1,200 cubic metres per second.

The city says they will lower the water level in the reservoir to make room for the incoming flow.

No overland is expected at this time, but the city says pathways along Calgary's rivers could be closed.

The fire department is asking all Calgarians to stay off the rivers and way from the water's edge.

Environment Canada says rainfall should taper off by Wednesday morning.
