Rivers are rising in southern Alberta after as much as 45 millimetres of rain fell in an area from Waterton to Lethbridge yesterday.
About 70 mm of rain were recorded along the Milk River ridge.
Alberta Environment forecasters say another 20 to 40 mm of precipitation is possible between now and tomorrow, adding to saturated ground and causing rural road closures in the County of Warner and possibly others.
As of last night, high stream flow advisories have been issued for the Waterton River above and below the Waterton Dam, Belly River, Castle River, Crowsnest River and Oldman River downstream of the Oldman Dam.
Water levels in the creeks under advisory in the Oldman River basin are rising steadily, and the Oldman Dam has increased outflows to match inflows.
High stream flow advisories remain in effect for Lee, Pincher, Drywood and Pothole creeks, the Milk River and all its tributaries, and all the tributaries flowing north out of the Cypress Hills.
