Flood Messages

A large weather system is impacting much of the Grand River watershed and periods of heavy rain are expected to continue through the day today. Some areas in the watershed have already received over 30 mm of rain in the last 6 hours, with more rain expected. Thunderstorms may increase the amount of rainfall in localized areas.

No significant flooding is expected with this event. However, intense rain can cause flows in rivers and streams to increase quickly and without warning. While widespread riverine flooding is not expected, there may be some flooding in low lying areas near watercourses and water may be ponded on roads in urban areas, if drainage systems are overwhelmed.
