Message:

A Severe Thunderstorm Warning has been issued by Environment Canada. The first of the thunderstorms are currently arriving in the west of the watershed and will be passing through the region over the next several hours. In addition to high winds and the possibility of hail, heavy rains are predicted. The region is predicted to receive at least 15 to 25 mm of rain, with thunderstorms possibly dropping 50 to 75 mm in some areas. Rainfall Warnings and/or Tornado Warnings could be issued later as the storms develop.

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. 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. It is too early to determine any potential impacts to Thames River water levels.

People should take extra caution and avoid the river, ditches, and streams. The combination of slippery banks, and fast-moving water can be dangerous. Standing water can also present its own unseen hazards. Children, pets and livestock should be kept away from the water. 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 July 28th, 2023.
