The Grey Sauble Conservation Authority says a low-pressure system is forecast to move across the Great Lakes region Wednesday.
It says strong west winds are expected to develop early in the morning and are forecasted to peak overnight and into Thursday morning. Maximum sustained wind speeds of 40-50 km per hour with gusts up to 80 km per hour are expected.
The conservation authority says offshore waves may exceed 3m in height.
They say, “Fortunately, water levels for Lake Huron have returned to near average conditions but there may still be a risk of shoreline erosion and near-shore flooding.”
The conservation authority notes, the areas most affected within the Grey Sauble Watershed will be the western shorelines along Lake Huron.
The Saugeen Valley Conservation Authority also put out a conditions statement:
“The Saugeen Valley Conservation Authority (SVCA) advises that a gale wind warning is in effect for the Lake Huron shoreline. By this evening, sustained wind speeds of 60 km/hr are expected from the south but will quickly change direction overnight to the west. Westerly winds gusting up to 90 km/hr will continue into Wednesday evening. Waves are expected to build to heights of 3 to 4m at this time.
Please note that strong winds and saturated soils will increase the risk of erosion along the Lake Huron shoreline. While significant shoreline flooding is not anticipated, wave uprush, shoreline erosion and flooding of low-lying areas is expected. Residents and municipal officials are reminded to stay well back from the Lake Huron shoreline at this time. Municipal staff are recommended to monitor problem areas into Thursday with forecast conditions.”
