Conservation Halton issued the following Watershed Conditions Statement – Flood Outlook at 1 p.m. on Tuesday, October 27, 2015.
Conservation Halton advises that the Environment Canada Weather Office is forecasting a low pressure system associated with the remnants of Hurricane Patricia will be moving into the Great Lakes region this evening. The system is expected to bring significant rainfall along with strong and gusty winds over the next couple of days. Rain will be heavy at times. Latest indications suggest 25 to 40 mm of rain in most areas with locally higher amounts of 40 to 50 mm possible, especially near Lakes Erie and Ontario. There is also the possibility of convective cells within the storm which could add an additional 10 to 20 mm in isolated locations.
The forecasted rainfall will result in higher than normal water levels and flows in all our streams and creeks, resulting in dangerous flow conditions. While no flooding is anticipated, watercourses will be flowing higher than normal causing local streams and creeks to become dangerous, especially in the vicinity of culverts and bridges.
Conservation Halton is recommending all residents and children 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 continue to make these locations extremely dangerous. Please alert children in your care of these imminent dangers.
Conservation Halton will continue to monitor stream and weather conditions and will issue further messages as necessary. This Watershed Condition Statement will be in effect through to Thursday, October 29, 2015.
