Conservation Halton advises that some areas of the watershed received over 25 mm of rain generated from the weather system that passed through the area last night. Environment Canada continues to have a Special Weather Statement in effect for the region 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. Conservation Halton reservoirs are still in range of 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.
The city of Hamilton is also reminding residents to take steps to prevent flooding in and around their homes.
The City is providing the following tips for residents to reduce the risk of flooding and monitoring the status of sewer overflows and wastewater treatment plant bypasses:
• Keep catch basins in front of your home clear of debris.
• If your home has a backwater valve installed, follow the manufacturer’s instructions for cleaning to ensure that it is functioning properly.
• Check your sump pump to make sure it is working properly.
• If your home or area is prone to flooding you may want to consider ensuring any valuables are up off of basement floors.
