The St. Clair Region Conservation Authority (SCRCA) has issued a flood watch for the Sydenham River.
SCRCA officials say upwards of 35mm of rain has fallen over the course of the past week and 50 to 55 mm of precipitation is is the forecast for the remainder of the week and into the weekend.
Water levels are expected to rise, there is fast flowing water and slippery stream banks and road closures have begun to occur.
“A low pressure system with a leading warm front is expected to bring 5mm of rain to the region today, followed by an anticipated 15-20mm of rain Thursday with a possibility for thunderstorms,” SCRCA officials stated.
“Periods of intense rain are possible, with increased precipitation possible in localized areas. Into Friday, a cold front trailing a low pressure system is forecasted to bring another 10 mm of rain, followed by approximately 20 mm of rain on Saturday. Scattered rain showers are also predicted for Sunday, bringing an additional 1-3 mm.”
SCRCA officials added: “Recent rainfall in addition to the forecasted rain is anticipated to result in water levels rising and remaining elevated into next week as the water makes its way through the rivers. Localized flooding in floodplain areas, parks and farm fields throughout the region is possible. Soils are anticipated to be saturated in certain areas across the watershed, resulting in the potential for increased flooding and runoff.”
Currently, Waterworks Road between Courtright Line and Moore Line is closed.
“River banks are expected to be slippery, with possible minor erosion,” SCRCA officials stated.
“Residents are reminded to avoid watercourses and flooded areas due to 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 flood watch will remain in effect until Tuesday, April 23, 2019 unless otherwise updated.
