Environment Canada has issued a special weather statement for Orangeville and the surrounding Grand Valley and southern Dufferin County area, warning residents to prepare for heavy rain this weekend. A weather system known as a Colorado low is expected to bring between 25 and 50 mm of rain to the region, with the most intense precipitation occurring from Saturday evening through Saturday night.
The weather service cautions that there is still some uncertainty regarding where the highest rainfall totals will fall. Thunderstorms are possible throughout the event, which could lead to locally higher amounts of rain. Because of these conditions, the agency may issue more specific rainfall warnings as the situation develops.
In response to the incoming storm, the Grand River Conservation Authority has placed the entire Grand River watershed under a flood watch, which remains in effect until 12 p.m. on Tuesday, April 7, 2026. Local officials have been advised to monitor water levels closely, particularly in flood-prone communities such as Grand Valley and Waldemar.
While the threat of flooding remains a concern, the conservation authority noted that their reservoirs are currently within their normal operating range for this time of year. These reservoirs will be managed to help reduce the potential impact of downstream flooding during the storm.
Orangeville residents may recall the severe flooding that occurred in June 2017, when a massive thunderstorm dumped 128 mm of rain on the area overnight, causing extensive damage to local streets. As the community prepares for this weekend, those living in areas historically prone to flooding are encouraged to review their emergency preparedness measures.
