Several local conservation authorities have issued flood watches and warnings this weekend, with anticipated rainfall and snowmelt expected to run off the frozen ground.
Maitland Valley Conservation Authority said that a survey conducted in the area on Thursday observed 60 to 100 mm of snow water equivalent on the ground in forested areas of the watershed.
The Upper Thames River Conservation Authority issued a similar warning, although it assured that flood control measures would likely control the majority of overflow.
With a near complete melt in Friday, and rainfall expected throughout the weekend, up to 25 mm of precipitation will join that snowmelt in filling local watercourses. Water levels could reach those experienced in Dec. 2008.
Sgt. Ed Sanchuck with OPP West Region took to X to issue some cautions to drivers, indicating that strong wind and heavy rain may cause pooling water and visibility issues. Hydroplaning is a hazard that drivers may encounter. Low lying areas also have a possibility of flooding.

Water levels will rise quickly on Saturday when a Colorado Low rolls through in the afternoon, likely exceeding bank full. There is the possibility of isolated thunderstorms that could bring higher levels of precipitation to isolated areas. The low pressure system will also cause temperatures to remain high, reaching nearly 20 degrees Celsius.
Southern parts of the region have lower levels of snow pack on the ground, which lowers the likelihood of flooding scenarios.
Municipal officials recommend checking drainage systems for obstructions, and monitor flood prone areas. Road closures due to flooding are likely.
