BURLINGTON, ON
Conservation Halton advises that some areas of the watershed received over 25 mm of rain generated from the weather system that passed through our jurisdiction last night. Environment Canada continues to have a Special Weather Statement in effect for our area and advises that the development of thunderstorms is possible this afternoon producing local rainfall rates of 25 mm to 50 mm per hour before the system tapers off later tonight.
Soil conditions within the watershed are saturated from recent rainfall and any additional rainfall 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. Further, heavy downpours associated with thunderstorms could result in flooding of highly urbanized areas. Municipalities, emergency services and individual landowners in flood-prone areas should be on alert.
Water levels in watershed creeks will rise significantly during the weekend. Caution around the edges of creeks – especially with children.
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.
Conservation Halton will continue to monitor stream flow and weather conditions and will issue further messages as necessary. This Flood Outlook Statement will be in effect through Sunday July 12, 2020.
