Calgary is bracing for a significant weather event on Sunday, with meteorologists predicting the city could receive up to 10 per cent of its annual precipitation in a single day. Jodi Hughes, a meteorologist at the Sky Watch Weather Centre, reported that a powerful storm system is expected to bring heavy rainfall to the region, potentially breaking daily records.
Forecast Details
The current forecast indicates that Calgary will experience sunny and calm conditions initially, but a dramatic shift is expected by Sunday. Hughes noted that the storm could deliver a substantial amount of rain, equivalent to roughly a tenth of the city's yearly average. This event is part of a broader weather pattern affecting southern Alberta.
Impact and Preparedness
Residents are advised to prepare for potential flooding and road closures. City officials are monitoring the situation and have urged citizens to clear storm drains and avoid driving through standing water. The heavy precipitation could also impact outdoor events and travel plans. Emergency services are on standby as the storm approaches.
According to Environment Canada, Calgary's average annual precipitation is about 412 millimetres. If the forecast holds, Sunday's rainfall could exceed 40 millimetres in some areas, making it one of the wettest days in recent memory.
Broader Weather Context
This storm comes as parts of Western Canada experience unusual weather patterns. Meanwhile, other regions are dealing with extreme heat, as seen in France where 40 drowning deaths have been reported as residents seek relief from record temperatures. The contrast highlights the diverse climate challenges facing different parts of the world.
Hughes emphasized that while the precipitation is significant, it is not unprecedented. However, the concentration of such a large amount of rain in a single day poses risks for localized flooding and infrastructure strain.
