Lake Huron Shoreline – Flood Outlook
Watershed Conditions Statement – Flood Outlook / Water Safety
Strong winds with gusts up to 70 km/hr may result in flooding and erosion problems along the Lake Huron shoreline.
A low-pressure system will move across Lake Huron today (Wednesday, January 8, 2020), bringing with it high winds. Strong northwest winds are expected to begin this morning and persist through the day, before decreasing this evening. Maximum sustained wind speeds of 45 kilometres (km) per hour, with gusts of up to 70 km/hr over Lake Huron are possible with this event.
The strong winds, combined with near record-high water levels on Lake Huron, will result in higher than normal waves hitting shoreline areas. This is expected to be a short duration event.
In addition to flooding of low-lying coastal areas, continued erosion of the lakeshore bluff is likely. Residents and municipal officials are reminded to stay well back from breaking waves, and also to stay away from top-of-bluff areas during and after the storm, in case there has been any movement of the lake bank. It is important to remember that there may be a delay between erosion at the toe (bottom) of the bluff and subsequent bluff failure.
This message will remain in effect until 9:00 a.m. on Thursday, January 9, 2020, unless local conditions warrant further updates. Maitland Conservation will continue to monitor watershed conditions and will provide an update if required.
