Sherwood Park and the Edmonton area are under a Yellow Warning for heavy rainfall, with Environment Canada forecasting significant rain and potential flooding through Wednesday morning. The storm could bring 50 to 100 mm of rain to the region, with localized amounts possibly reaching 150 mm east of Edmonton.
The warning, first issued Sunday May 31 at 4:41 a.m. MDT and updated Monday, June 1, 2026, at 10:48 a.m. MDT, notes that heavy rain will continue, with additional accumulations of 30 to 70 mm expected through Tuesday. As of early Monday, some spots in Alberta had already recorded 60 to 80 mm of rain since the storm began. The deluge follows an unusually dry May, when Edmonton received just 5 mm of precipitation, well below the normal of 44 mm.
Strong north winds of 40 km/h gusting to 60 km/h are also expected Monday, with gusts up to 80 to 100 km/h possible in parts of central and southern Alberta, as a low-pressure system stalls near the Alberta-Saskatchewan border. The combination of heavy rain and wind increases the risk of localized flooding and washouts near rivers, creeks, and culverts.
The Alberta River Forecast Centre is monitoring rising river levels due to warm temperatures and faster-than-normal mountain snowpack melt. A flood watch is in effect for the Pipestone River and the Bow River near Lake Louise, with a high streamflow advisory for the Bow River from upstream of Banff to the Ghost Reservoir.
Strathcona County Emergency Services advises residents to avoid driving through flooded roadways and to report sewer backups or basement flooding by calling 780-467-7785 at any time. For emergencies, call 9-1-1. Conditions are expected to improve by Thursday, June 4, with a return to sunnier skies and highs of 20 to 22 C.
