The Maitland Conservation Flood Forecast Centre has issued a watershed statement for much of the area after last nights thunderstorms.
As of 6 a.m. this morning, 24-hour rainfall totals ranged from 30 to 125 mm, with heaviest amounts generally concentrated in a wide corridor extending from Goderich to Howick.
The greatest intensity of rainfall was recorded in the Wingham area, where a total of 125 mm was received, 80 mm of which fell in less than two hours.
Significant flooding is not expected but river levels will rise throughout the day, especially along the Lower Maitland downstream of Wingham.
Campgrounds and anyone participating in recreational activities within or near river lowlands are advised to use caution and be aware of the potential for fast changing conditions. People are encouraged to defer recreational activities on the river until next week.
Conservation staff will be closely monitoring the situation over the next 48 hours and will provide an update if conditions change.
This statement will remain in place until 4 p.m. on Monday, August 8.
