A large low pressure area over the Northern Plains States will track across northwestern Ontario tonight, then over far northern Ontario on Tuesday. This storm track will keep areas near Lake Superior and northern Lake Huron in the milder air today and tonight, with a significant rainfall expected.

Rain has already begun near Lake Superior and will begin this afternoon for areas farther east. The rain will continue throughout the day into this evening before ending by Tuesday morning with the passage of a sharp cold front.

Total rainfall amounts of 25 to 50 mm are likely. Total rainfall amounts of 50 to 60 mm are possible in areas that receive a brief thunderstorm.

Heavy downpours can cause flash floods and water pooling on roads. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop.

Rainfall warnings are issued when significant rainfall is expected.
