Its going to be a wet weekend.
Sarnia-Lambton is included in a special weather statement from Environment Canada.
The national weather agency says rain, heavy at times, is expected to move into southwestern Ontario Friday night and will persist into Saturday.
Total rainfall amounts of 25 to 40 mm are likely, although some areas may receive higher amounts. The rain is expected to taper off Saturday evening.
Environment Canada says the rainfall is associated with a developing low pressure system that will cross the lower great lakes.
