Both the Ausable Bayfield and Maitland Valley Conservation Authorities are warning of the potential for flooding and erosion along the Lake Huron shoreline.
In two releases this afternoon, officials said there are two weather systems moving through southern Ontario over the next several days.
A cold front is moving in today, bringing sustained winds over 40 kilometres per hour and gusts over 70 kilometres per hour. Those are expected to ease by tomorrow morning.
This weekend, the low-pressure system is expected to impact the watershed with winds over 50 kilometres per hour, gusting to 80 kilometres per hour. The wind is forecast to peak Sunday and diminish by Monday morning.
Yet again, the wind and high lake level are combining to continue the erosion of the shoreline bluffs and bring flooding to low-lying coastal areas. The Ausable Bayfield Conservation Authority warned the "saturated lake banks and absence of shoreline ice will increase the erosion potential with this event."
The Maitland Valley Conservation Authority said freezing spray will create hazardous walking conditions along the shoreline and cause ice build-up on low-lying shoreline structures.
Residents are asked to stay well back of breaking waves and avoid the top of the bluffs until well after the storms have passed.
