Highlights:

• High winds, wave action and freezing spray
• Possible erosion on southern Lake Huron

A low pressure system is expected to move through Ontario this week, bringing strong winds from a north-easterly direction starting today, switching to a westerly direction overnight into Thursday morning. Wind speeds upwards of 55 km/h are anticipated Thursday into early Saturday morning, with strong gusts upwards of 80 km/h starting later today through to Saturday.

A gale wind warning and freezing spray warning are in effect for southern Lake Huron; freezing spray is anticipated beginning later this evening. Waves one to one and a half metres are expected to build to two metres this evening and three metres Thursday morning.

Residents along the Lake Huron shoreline may experience wind-driven high water levels and wave action, with a potential for erosion. Winds from a westerly direction also have the potential to cause a backwater effect in the Wallaceburg area, slowing the flow of water out of the Sydenham River and contributing to elevated water levels.

River banks are expected to be slippery, with possible minor erosion. Residents are reminded to avoid watercourses and flooded areas due to slippery banks and cold, swift moving water. Children and pets should be kept away from the water.

The Conservation Authority continues to monitor watershed conditions and will issue advisories to municipalities and media should flood issues arise.

Municipal emergency response staff and road superintendents should monitor local conditions closely.

This message will remain in effect until Monday, March 2, 2020 unless otherwise updated.
