The Lake Simcoe Region Conservation Authority advises that a slow-moving low-pressure system is expected to move across Lake Simcoe watershed starting late Friday through Monday. A series of precipitation events are forecast to bring a mix of snow, rain, freezing rain, and ice pellets. The forecast is currently calling for up to 60 mm of precipitation over the next four days. The temperatures will be well above seasonal values with daytime highs climbing above +10 degrees Celsius.
While widespread flooding is not expected, the possibility for flooding in various low-lying areas of the watershed exists due to the expected rainfall and saturated ground conditions. Watercourses will be flowing at higher-than-normal levels, causing local streams and rivers to become dangerous, especially in the vicinity of culverts and bridges. Children and pets should be warned to stay away from all watercourses and slippery banks.
This watershed conditions statement will be in effect through Wednesday, April 2, 2025, at 5 p.m.
