Environment Canada is tracking a line of severe thunderstorms that may be capable of producing strong wind gusts and heavy rain early this evening and into the overnight hours. Forecasts predict rainfall amounts of 25 to 30mm for the region, with the potential for higher precipitation amounts in localized areas. Due to the potential intensity of the thunderstorms flash flooding and ponding may occur. 

Water levels are anticipated to be elevated from the rainfall with the potential for minor flooding into natural floodplain areas, parks and fields; major flooding is not anticipated at this time.

Individuals are reminded to avoid watercourses and flooded areas due to dangerous conditions, slippery banks and cold, swift moving water. Children and pets should be kept away from the water.

The Conservation Authority continues to monitor watershed conditions and will issue advisories to municipalities and media should flood issues arise.

Municipal emergency response staff and road superintendents should monitor local conditions closely.

This message will remain in effect until Monday, May 27, 2024 at 12pm unless otherwise updated.
