The Hamilton Conservation Authority (HCA) is advising of the possibility for localized flooding in low-lying areas within the watershed, as a result of potential rain and thunderstorm activity forecasted for Monday night and Tuesday.
A complex low pressure system is forecast to cross southern Ontario Monday evening (August 11) and Tuesday (August 12).
The Hamilton area could potentially receive significant rain as a result of this system.
Current water levels within some major watercourses are at normal conditions. In other major watercourses (including Spencer Creek), water levels are slightly elevated, but well below critical levels and presently receding.
The forecasted rainfall could result in significant amounts of runoff. This may result in rapidly increasing water levels and flows in area watercourses, with the potential for localized flooding in low-lying areas. In addition, the forecasted rainfall may result in drainage issues in low-lying or poorly drained areas, and storm sewer systems may become overwhelmed in intense rainfalls over short durations.
A close watch on local conditions is recommended. It is advised that people exercise caution near all water bodies, as fast moving water and slippery banks may pose a significant hazard. Adults are advised to keep children and pets away from water bodies at this time.
The warning is in effect until Wednesday, Aug. 13, at which time it will either be updated or cancelled.
HCA continues to monitor weather and stream conditions closely.
