Message:

A Special Weather Statement has been issued by Environment Canada due to significant rain in the forecast. Weather forecasters are currently tracking a strong low pressure weather system moving across the province. This system has already brought 10 to 15 mm of rain to the lower Thames River watershed since it began last night. Forecasts suggest an additional 15 to 30 mm of rain could be seen today, and another 10 to 15 mm could be seen on Friday. Localized areas of higher rainfall totals could be seen, and thunderstorms are also possible.

The amount of rain in the forecasts will create ponding, areas of standing water and localized flooding. This rain will also cause our smaller watercourses to rise, and some could spill their banks into adjacent low-lying areas. Based on the forecasted rainfall amounts, the LTVCA expects to operate the McGregor Creek Diversion Channel at Chatham. Water levels on the smaller watercourses should be expected to remain elevated through the weekend.

Significant flooding along the lower Thames River is not expected at this time. However, the river will rise and may reach into some low-lying areas immediately adjacent to the river. Should a significant rise in the river be expected, a follow-up message will be issued. Water levels on the river should be expected to remain high through the weekend into early next week.

People should take extra caution and avoid the river, ditches, and streams. The combination of slippery banks, and fast-moving cold water can be dangerous. Children, pets, and livestock should be kept away from the water.  Standing water can also present its own unseen hazards. As water levels rise, it is not safe to take shelter along riverbanks or in low-lying areas that are prone to flooding.

Officials will continue to monitor the situation and update this advisory as necessary.

This message will be in effect until April 15th, 2024.
