Environment Canada has issued a rainfall warning for most of Southwestern Ontario, including Windsor-Essex and Chatham Kent.
According to the statement, rainfall combined with melting snow continues and frozen ground is leaving standing water throughout the region.
Rain is expected to continue into Sunday night — heavily at times with amounts likely in the 20 to 30 mm range — light rain is expected into Monday.
Environment Canada says the total rainfall amounts for the weekend may be in the 30 to 40 mm range with localized amounts of 50 to 60 mm.
Localized flooding in low-lying areas is possible as has been the case in parts of Essex County.
