The Lower Thames Valley Conservation Authority (LTVCA) has issued a flood outlook for smaller watercourses and the Thames River, warning of potential localized flooding as warm temperatures and rainfall increase runoff into waterways.
Daytime highs reached 10 degrees Celsius in Ridgetown, 12 degrees in Windsor, and 7 degrees in London on Tuesday, accelerating snowmelt across the region. Some areas with lower initial snow accumulation have already seen significant melt. Trace amounts of precipitation were also recorded.
A weather system moving into the region Wednesday afternoon is expected to bring between 3 and 10 millimetres of rain over the next 24 hours. Temperatures will remain slightly above freezing overnight before dipping below freezing again Thursday night into Friday morning. These conditions will contribute to additional snowmelt and runoff.
Smaller watercourses in the region have already been affected by the snowmelt, with some experiencing blockages due to broken ice and debris. This has led to ponding, standing water, and localized flooding in certain areas.
While water levels in some watercourses have begun to recede, further rain and melting could cause levels to rise again. The LTVCA has indicated that it may need to operate the McGregor Creek Diversion Channel if necessary. Authorities urge residents to consider any remaining ice on local waterways unsafe and to avoid it.
The Thames River is also responding to the recent thaw, with water levels rising and ice separating from the riverbanks in many areas. Some sections of the river have seen ice melt where warm water has entered, though a full breakup of river ice is not expected at this time. Officials warn that the ice on the Thames River remains unstable and should be avoided. Flooding from the river is not anticipated at this stage.
Residents are urged to stay clear of rivers, ditches, and streams, as slippery banks, unstable ice, and fast-moving cold water pose significant risks. Standing water may also conceal unseen hazards. Parents and pet owners are advised to keep children, pets, and livestock away from water bodies.
Officials will continue monitoring conditions and provide updates as needed. This advisory remains in effect until Feb. 28.
