Flood Warning issued for Lake Erie shoreline, residents advised to avoid unnecessary travel

A Flood Warning has been issued for areas along the Lake Erie shoreline, along the Grand River downstream of Dunnville Dam & Port Maitland. Strong southwesterly winds gusting to near 100 km/h will develop suddenly early this evening as a sharp cold front blasts through, causing high waves and hazardous conditions.

This event is particularly a concern due to the snow currently falling and predicted, as well as the cold temperatures. Visibility could be an issue, as well as icy road conditions, plus ice buildup on homes/cottages along the lakeshore.

“Residents should stay indoors and not travel unless absolutely necessary during this winter storm event,” said Haldimand County Fire Chief & Manager of Emergency Services Jason Gallagher. Gallagher noted that the Port Maitland Pier has been closed and members of the public should stay clear of all shoreline areas. Haldimand County Emergency Services & Public Works Operations crews are standing by to implement road closures and respond as necessary.
