Chestermere is in for a wet start to the week as a slow-moving weather system brings heavy rain to the area. Environment Canada has issued a rainfall warning for Rocky View County near Chestermere, with total amounts of 50 to 80 mm expected. Showers and a risk of thunderstorms are forecast to continue through Monday, with local rainfall of 10 to 20 mm possible.
As of Monday afternoon, conditions at the Calgary International Airport were mostly cloudy with a temperature of 20°C and north winds gusting to 46 km/h. The rain is expected to ease Monday night, giving way to a mix of sun and cloud on Tuesday. Tuesday’s high will reach 25°C, though there is still a 30 percent chance of showers.
The heavy rain is part of a larger weather pattern affecting much of Alberta this month. The Weather Network says moisture from the Gulf of Mexico has been fuelling repeated heavy rainfall events across the province. A Rex block pattern is causing low-pressure systems to stall, acting like an atmospheric traffic jam and raising the risk of localized flooding.
While the rain may be a nuisance for some, it comes after a prolonged dry spell in the region. Chestermere Lake, which is part of a managed irrigation system run by the Western Irrigation District, has seen fluctuating water levels due to drought conditions. The district began refilling the lake in April 2024, but water levels can still vary depending on weather and demand.
Sunny skies and a high of 26°C are expected by Thursday, offering a break from the wet weather. For now, residents are advised to watch for ponding on roads and to stay alert for changing conditions.
