The combination of rain and melting snow could lead to some significant flooding in low-lying areas, according to the Upper Thames River Conservation Authority.
The UTRCA says between 20 and 50 mm of rain has fallen over the last 48 hours over the watershed, and an additional 5 to 10 mm is expected Thursday.
“Water levels will begin to peak later today in upstream locations, such as Mitchell, Stratford, and Innerkip,” said Mark Helsten, UTRCA Senior Water Resources Engineer.
“The crest will move downstream throughout today and the Thames River will peak in Byron early on Friday.”
Residents are being reminded to use extreme caution near all rivers, streams, ditches, and ponds and watch for flooding in low-lying areas, including Harris Park and potentially Gibbons Park.
Seasonal freezing temperatures are forecast to return Thursday, but warm temperatures and rain are again possible early next week.
The Catfish Creek Conservation Authority has issued a Flood Watch for low lying flood prone areas within the watershed. The watch will remain in effect for at least the next 24 hours.
The Kettle Creek Conservation Authority also issued a flood outlook on Thursday.
“Currently the creek is flowing higher than normal,” said Jennifer Dow, water conservation supervisor for Kettle Creek Conservation Authority.
“With additional rain in the forecast, the creek’s water levels will continue to increase however serious flooding is not expected.”
Parents are being advised to keep their children and pets away from watercourses at this time.
