A stretch of wet and windy weather is settling over Lethbridge, Alberta, as Environment Canada has issued a Yellow Rainfall Warning for the city. The warning, in effect Monday, June 1, 2026, is expected to last through Tuesday, bringing significant rain and gusty winds before conditions improve later this week.
Rain, at times heavy, is forecast for Monday, with 10 to 20 mm likely and northwesterly winds of 40 km/h gusting to 60 km/h. The high is expected to reach 11°C. Tuesday will see rain continue with another 5 to 10 mm and winds of 30 km/h gusting to 50 km/h, again topping out near 11°C. By the time the system moves out, storm totals could range from 50 to 100 mm for most of the region, with localized amounts possibly hitting 150 mm, particularly for areas east of Edmonton.
Environment Canada warns that water will pool on roads and in low-lying areas. Residents should avoid driving through flooded streets and stay alert for washouts near rivers, creeks and culverts. The city and surrounding areas remain under a moderate-impact warning, but forecasters have very high confidence in the rainfall timeline.
The silver lining comes midweek. Wednesday, June 3, is expected to bring a mix of sun and cloud with a high of 18°C as skies begin to clear. Thursday warms up to 22°C under a mix of sun and cloud, with a 30 percent chance of showers and a risk of thunderstorms. Friday looks even brighter with sunny conditions and a high of 22°C, offering a pleasant end to the first week of June.
While the rain may seem dramatic, June is historically the wettest month in Lethbridge, with average precipitation ranging from 66 mm to 100 mm. This week’s downpour fits that pattern, but the rapid shift to sunshine by the weekend will be a welcome change for residents.
