It was a year ago that Sault Ste. Marie experienced it’s worse flood in decades. Heavy rain fell non-stop for hours as roads were washed away, rivers overflowed, the underpass was under water and several homes were flooded out. Could today bring an encore?
Not likely, but the rain could produce some localized flooding in areas.
Rain is expected to start by noon and last through Thursday morning. A slow moving system tracking from the southwest to northeast could leave 50mm in its wake. An upper level system with an extended cold front will move through tonight dropping temperatures to very cool values – with highs only expected to reach 11c. The chilly air will stick around for at least four days.
Here’s the latest from Environment Canada:
A low pressure system over Iowa will be tracking northeastward towards the Great Lakes today. A broad area of rain ahead of the low will begin moving into Northeastern Ontario today and continue into early Thursday. Rain could be heavy at times and may be accompanied by thunderstorms tonight. General rainfall amounts in the 20 to 40 range are expected, but higher amounts may be possible locally.
A rainfall warning is in effect for areas northeast of Lake Superior where 50 mm or more of rain is expected within 24 hours.
