A prolonged heavy rainfall event is drenching Sylvan Lake, Alberta, with Environment Canada warning that an additional 30 to 70 millimetres of rain could fall through Tuesday. The rainfall warning, which covers Red Deer County near Sylvan Lake, was updated late Monday morning and warns that storm totals could reach 50 to 100 millimetres for most areas, with localized amounts up to 150 millimetres possible further east. The downpour follows an unusually dry May across much of Alberta, meaning some communities could see more rain in just a few days than they normally get in all of June.
As of noon Monday, the Red Deer Regional Airport reported light rain, a temperature of 9°C, and northwest winds gusting to 58 km/h with 92 per cent humidity. While a wind warning that had been in place for Red Deer County was lifted Monday morning, residents are still urged to exercise caution around gusty conditions, especially near trees and power lines. The main threat remains the steady, heavy rain that is pooling water on roads and in low-lying areas.
Environment Canada is advising people not to drive through flooded roadways and to watch for washouts near rivers, creeks, and culverts. The Alberta River Forecast Centre is monitoring stream flow conditions, and officials say rapidly rising water levels could create dangerous situations. Homeowners should ensure sump pumps are working and clear any debris from storm drains to help prevent localized flooding.
The relentless rain, driven by a slow-moving low-pressure system, began over the weekend and is expected to taper off by Wednesday morning. Relief is on the horizon, with a mix of sun and cloud and temperatures reaching 21°C in the forecast for Thursday. For now, Sylvan Lake residents should stay off flooded roads, tie down loose outdoor items, and stay tuned to local alerts as the storm passes.
