Ahead of the Thanksgiving long weekend, fears of heavy rain are fueling a special weather statement for parts of north.

Environment Canada has issued a special weather statement for Elliot Lake - Ranger Lake, Manitoulin - Blind River - Killarney and Sault Ste. Marie - Superior East.

“Rain at times heavy is expected Saturday and Saturday evening,” reads a weather alert.

“Rain ahead of a low pressure system is expected to begin overnight and become heavy on Saturday. Total rainfall amounts of 30 to 40 mm are possible. However, some areas could receive rainfall amounts near 50 mm by the time the rain ends Saturday night.”

A rainfall warning is also in effect for Sault Ste. Marie - Superior East and Wawa - White River – Pukaskwa.

“At this time there is some uncertainty in the exact location of the highest rainfall amounts,” said Environment Canada.

“It appears that the heaviest rain will fall near Lake Superior to the north of Sault Ste. Marie where a rainfall warning is in effect. However, Environment and Climate Change Canada will closely monitor the situation and issue additional rainfall warnings if necessary.”
