The Catfish Creek Conservation Authority has issued a Watershed Condition Statement for the shoreline of Lake Erie.
As of 7 a.m. Monday, the Lake Erie water elevation at Port Stanley was 1.543 metres above normal, suggesting a high wave forecast.
Elevation may be higher along the Waneeta Beach area, Port Bruce Provincial Park beach and the harbour areas.
Winds are expected to increase into Tuesday, but diminish by the afternoon.
Residents are being asked to stay away from Lake Erie shoreline areas when experiencing strong waves and higher water levels.
This statement is in effect until noon on Wednesday.
