A line of thunderstorms incoming from Lower Michigan will reach southwestern Ontario late this afternoon. Strong to damaging winds and heavy downpours associated with thunderstorms may produce local amounts of 50 to 75 mm of rain. This rainfall may occur over a relatively short period of time. Rainfall is expected to continue into Thursday morning.
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.
River banks are expected to be slippery, with possibility for minor erosion. Residents are reminded to avoid watercourses and flooded areas due to slippery banks and 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 Friday, July 28, 2023 at 12pm unless otherwise updated.
