Highlights:

• Rainfall Warning issued by Environment Canada
• Remnants of Hurricane Beryl will pass through the region and could drop significant amounts of rain
• Rainfall amounts will depend on the track of the system, which is still somewhat uncertain.
• Rainfall Warning suggests the region could see 40 to 60 mm of rain with torrential downpours at times.
• Thunderstorms could produce localized higher amounts of rain.
• Areas of ponding, standing water and localized flooding could be seen around the watershed.
• Smaller watercourses will rise, and some could spill their banks.

Message:

A Rainfall Warning has been issued by Environment Canada. As the remnants Hurricane Beryl pass through the region, the downgraded weather system is still expected to drop considerable amounts of rain. There is still some uncertainty in the track of the weather system and as a result, rainfall amounts could vary quite a bit from current predictions. The Rainfall Warning suggests the region could see 40 to 60 mm of rain, with torrential downpours at times, and the possibility of thunderstorms. As a result, localized areas could see more than these predictions suggest. Historically, remnant hurricanes tracking like this have dropped over 100 mm is some areas. The rain is expected to begin overnight and could last into Thursday.

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. If the higher rainfall amounts appear, the LTVCA may need to operate the McGregor Creek Diversion Channel at Chatham.

It is too early to say how much the Thames River may rise as a result of this weather system. 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.

People should take extra caution and avoid the river, ditches, and streams. The combination of slippery banks, and fast-moving 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 July 12th, 2024.
