Southern Alberta is bracing for a significant weather event as Environment Canada issued a yellow severe thunderstorm watch Tuesday covering Calgary, Lethbridge, Medicine Hat, and surrounding communities.
The national weather agency forecasts conditions are ripe for severe thunderstorm development Tuesday afternoon and evening, with the potential to produce dangerous wind gusts, large hail, and torrential rainfall. Environment Canada also noted a slight risk of tornado activity in the region.
Weather experts anticipate the most intense storm activity will peak around 4 p.m., with residents advised to monitor conditions closely and prepare for rapid weather changes.
What Albertans Should Expect
In the Lethbridge and Medicine Hat areas, wind gusts could reach up to 80 kilometres per hour—powerful enough to cause significant damage to trees, buildings, and vehicles. Calgary residents can expect somewhat lighter conditions, with wind gusts up to 60 km/h forecasted, tapering to around 20 km/h by Tuesday evening.
Heavy rainfall and hail of concerning size are also possible across the watch area, presenting hazards for motorists and outdoor activities.
Context: Recent Tornado in Northern Alberta
The severe weather watch comes on the heels of a confirmed tornado that touched down near Girouxville in northern Alberta around 8:30 p.m. Tuesday. The tornado struck approximately 60 kilometres south of Peace River, adding urgency to the current weather warning across the southern province.
Residents across Calgary, Lethbridge, and Medicine Hat are encouraged to stay weather-aware, secure outdoor items, and have an emergency plan in place before conditions deteriorate.
