Vermilion, Alberta remains under a severe thunderstorm watch as Environment Canada warns heavy rain could worsen already high flood risks across the region. The Yellow Watch, issued Monday afternoon, means conditions are right for storms that may bring strong winds, large hail, and more downpours. After a weekend of drenching rains and one of the wettest Junes on record, the ground is saturated and local rivers are running high.
The Environment Canada alert notes the severe thunderstorm threat will continue into the evening. While the heavy rainfall that triggered earlier orange warnings is easing, the saturated ground means any additional rain could quickly lead to flooding. Earlier warnings had called for 40 to 70 mm of rain across central Alberta, and some areas have already seen more.
Edmonton just logged its wettest June ever, recording 244 mm of rain by June 27, smashing the old record of 216.5 mm set in 1914. The same weather pattern that soaked the capital also hit Vermilion, leaving fields and ditches full. The Vermilion River, which stretches 255 km and flows through the county in its lower course, is dammed at the town and is swollen from days of steady rain. A separate flood study for Vegreville, finalized in November 2025, mapped 19 km of the Vermilion River and 24 km of its tributaries through Vegreville and Minburn County to help regional communities prepare for exactly this kind of event.
The situation in nearby Tofield, about 50 km away, shows how serious the flooding can get. That town declared a state of emergency and cancelled its Canada Day events after heavy rain overwhelmed its wastewater system. Vermilion residents are being told to steer clear of rivers, creeks, and low-lying roads, and never try to drive through flooded areas.
There is relief in sight: the forecast calls for a mix of sun and cloud starting July 4, with a high of 23°C, and 25°C by July 5. That drier weather should help water levels start to drop, but officials caution that the risk will linger until then. Local leaders in the County of Vermilion River are keeping a close eye on conditions and say emergency services are ready if needed.
