The Grand River Conservation Authority has issued a flood warning for Lake Erie.
Officials say there will be winds gusting up to 70 km/h by early Sunday morning. After that, stronger winds will come in at 100 km/h on Sunday afternoon.
The strong winds are expected to ease by Monday morning, and the GRCA says there will be about 10-15 millimetres of rain in the Haldimand area on Sunday.
They say that according to a surge model forecast for the east end of Lake Erie, levels may rise by 2.98 metres (9.8 feet).
As a result, there may be potential flooding along the shoreline of Lake Erie and at Dunnville Dam, which is downstream on the Grand River.
You are being asked to stay away from Lake Erie because of dangerous conditions, with strong wind and high water levels.
Children and pets must be kept away from the area until the current high-level flood watch message expires on Monday at 8 a.m.
