Message:

Weather forecasters are currently tracking a low pressure system expected to bring widespread rain across the region this weekend. Environment Canada has issued a Special Weather Statement suggesting that rainfall totals of 20 to 40 mm could be seen, starting late this afternoon through Saturday. Localized areas of higher rainfall totals could be seen. Environment Canada advises that the message could be upgraded to a Rainfall Warning as the event develops. As the event tapers off late Saturday, the rain could change over to snow as temperatures drop.

The amount of rain in the forecasts could 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. If the higher rainfall amounts appear, the LTVCA may need to operate the McGregor Creek Diversion Channel at Chatham and is prepared to do so if necessary. Water levels should be expected to remain elevated through the weekend, possibly into early next week.

At this time, it is uncertain how much the Thames River may respond to these rains. Should a significant rise in the river be expected, a follow-up message will be issued. Flooding from the river is not expected at this time.

With students off for the March Break, parents and guardians are reminded to keep children and pets away from all watercourses. The combination of slippery banks, and fast-moving cold water can be dangerous. 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 March 11th, 2024.
