The St. Clair Region Conservation Authority has issued a Flood Watch as a result from the 25-50mm of rain over the past 24 hours and the forecasted 20-50mm this afternoon as well as the 20-35mm overnight into Thursday morning.
The total amount of rainfall in the 48 hour period could exceed 130mm, though it may vary. Due to all of this rain, it can lead to increased runoff and flash flooding, especially in urban areas. Water levels are beginning to rise already in the watershed and are anticipated to elevate into natural floodplain areas, parks and farm fields. Soils are expected to be saturated from the rain and could contribute to ponding, increased runoff into watercourses, and possible increased erosion and seepage issues
The Authority has extended the Flood Watch until Sunday September 26th, from the previous date of Friday September 24th.
