The Saugeen Valley Conservation Authority (SVCA) advises that a Rainfall Warning is currently in effect over our jurisdiction. A strong low-pressure system will be moving across Ontario today and Wednesday, bringing thunderstorms and heavy rain to the area. The watershed could receive between 75 to 95 millimeters of rain in 48 hours, with locally heavier downpours possible in areas that receive multiple thunderstorms. A gale warning is also in effect for the southern Lake Huron shoreline, with south winds building to 40 km/h and gusting to 70.
Higher than normal water levels and flows can be expected in streams, especially in the vicinity of culverts and bridges. Minor flooding is possible in traditional low-lying areas, and heavy downpours may cause flash floods and water pooling on roads. More extensive flooding is possible should the region receive rainfall amounts greater than what are currently forecast. Municipal and County staff should monitor problem areas and prepare to close low-lying roads.
Residents are reminded to stay away from all watercourses and structures such as bridges, culverts, and dams. Elevated water levels, fast flowing water, and slippery conditions along stream banks make these locations extremely dangerous. Extra caution should also be taken along the Lake Huron shoreline due to strong winds and high wave action.
This Flood Outlook Statement will be in effect through Friday September 24, 2021, or until further notice. The Saugeen Valley Conservation Authority will continue to monitor stream conditions and will provide updates as required.
