LETHBRIDGE, AB – Many areas of Southern Alberta are under heavy rainfall warnings, flood warnings and watches, and high streamflow advisories.

Waterton Lakes National Park has been under a Flood Watch since Monday, June 13th, 2022, and Parks Canada officials say they are closely monitoring water levels, weather conditions, forecasts, and infrastructure status throughout the park.

Parks Canada says Waterton has received about 35 millimetres of precipitation in the past 48 hours, and an additional 10-20 mm of rain is expected before Wednesday, June 15.

As of 5:00 p.m. on Tuesday, June 14, Environment Canada states that heavy rainfall warnings are still in effect for Waterton and the following areas:

• Municipal District (M.D.) of Pincher Creek
• M.D. of Ranchland
• Municipality of Crowsnest Pass including Coleman and Frank
• Piikani First Nation
• Blood Tribe First Nation

Environment Canada says prolonged periods of heavy rain could bring between 50 and 70 mm of rain to these areas, and up to 150 mm or more in areas along the Foothills and the front range of the Rocky Mountains.

Environment Canada warns that this amount of precipitation could cause flash flooding and possible washouts near rivers, creeks, and culverts, so people are being asked to use caution and avoid going near fast-moving creeks and rivers.

West of the Crowsnest Pass, the continued rain and flood risk is leading to evacuations in southeastern BC.

A rainfall warning has not been issued for the Lethbridge region; however, more than 27 mm of rain has fallen since Monday, and another 10-35 mm is expected before Wednesday.

To the north, a local state of emergency was declared as Calgary prepares for potential flooding along the Bow and Elbow rivers.

In addition to the flood watches in Waterton and areas near Calgary, the provincial government has continued high streamflow advisories for several other waterways across southern Alberta.

High streamflow advisories are in effect for the Oldman River basin, the Belly River, the Waterton River, the Waterton Reservoir, Willow Creek and other waterways between the Crowsnest Pass and Lethbridge, as well as east toward Taber.

Environment Canada forecasts that the rain will ease in most areas of southern Alberta by late Wednesday, June 14, 2022.
