The warning includes communities in and around Greater Sudbury, North Bay and Parry Sound. The warnings in the vicinity of Sault Ste. Marie have now been lifted.

“Scattered showers continue this (Sunday) morning and are expected to become more widespread through the late morning and early afternoon,” Environment Canada said.

The rainfall is expected to be heavy at times, meteorologists predict, with an additional 10 to 25 mm in most areas.

“Heavy downpours can cause flash floods and water pooling on roads,” reads the warning.

“Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks and culverts.”
