The Flood Watch for the Lake Erie shoreline has been upgraded to a Flood Warning. With high winds in the forecast, there is a risk of flooding in low-lying areas of the Lake Erie shoreline and downstream of the Dunnville Dam in Port Maitland.

The Ministry of Natural Resources and Forestry (MNRF) is forecasting sustained strong southwest and west winds ranging from 40 to 50 km/hr, and gusts in excess of 60 km/h Thursday afternoon continuing into Friday. Some light, mixed precipitation is also expected to accompany this event.

The MNRF surge model forecast for the eastern end of Lake Erie is indicating a rise in levels of 2.06 metres (6.8 feet) above chart datum of 173.5 m IGLD85 at the gauge in Port Colborne. The peak above critical level is forecast to occur Thursday evening between approximately 8:00 p.m. and 12:00 a.m. Waves of up to 0.85 m are expected.

After receding overnight, a second peak with surge forecast just below warning levels is forecast for Friday morning. Water levels are expected to remain elevated until Friday morning.

People are urged to stay away from Lake Erie shoreline areas experiencing strong wave action and elevated water levels. Parents are reminded to keep children and pets away from these areas.

Haldimand County Emergency Services will be actively monitoring lake conditions and is prepared to respond if necessary. Residents should pay close attention to changing weather conditions and watch for updated flood messages. A flood guide for lakeshore property owners and other emergency preparedness resources can be found at HaldimandCounty.ca/floods.
