Conservation Halton says the Ministry of Natural Resources is forecasting an incoming low-pressure system that will bring up to 40 mm of rain over our jurisdiction beginning Sunday afternoon with a chance of thunderstorms leading to an additional 10 to 25 mm locally. An additional 10 to 30 mm is possible on Monday before the system moves out of our jurisdiction.
Soil conditions within the watershed are saturated from recent rainfall meaning that much of the forecasted rain on Sunday and Monday will runoff into our rivers and streams. The combination of increased flows and water levels and slippery and unstable banks will create hazardous conditions close to any rivers, streams, or other water bodies.
Widespread flooding is not anticipated. Our reservoirs are still in range of our seasonal holding levels and have storage capacity available. However, fast flowing water and flooding of low-lying areas and natural floodplains may be expected. Municipalities, emergency services and individual landowners in flood-prone areas should be on alert.
Conservation Halton is asking all residents and children to keep a safe distance from all watercourses and structures such as bridges, culverts and dams. Elevated water levels, fast flowing water, and slippery conditions along stream banks continue to make these locations extremely dangerous. Please alert children in your care of these imminent dangers.
