Special Weather Statement

Issued at 19:53 Wednesday 28 June 2017

A soaking significant rainfall on tap.

A low pressure area over Minnesota will slowly track east towards
Lake Superior tonight, reaching Northern Lake Huron on Thursday. This weather system will bring a large area of showers and embedded
thunderstorms with it tonight through Thursday night.

Latest indications suggest a general rainfall of 20 to 40 millimetres is possible by Friday morning. However, there is some potential for moisture laden thunderstorms to boost total amounts to near 50 millimetres or more, especially in areas that receive two or more thunderstorms in a row.

There remains some uncertainty to location of the heaviest rainfall
amounts at this time due to the track of the low, and locations where thunderstorms may develop.

Environment Canada continues to monitor this weather system closely.
