Rainy Week in the Forecast
Watershed Conditions Statement – Flood Outlook
2026 Flood Event 5, Bulletin Number 1 (Issued April 13, 2026, at 15:30; Valid until April 20, 2026, at 12:00 noon)
A moisture‑laden frontal system will be over the southern region of the province for the next four days, starting today (Monday). Widespread rainfall and shower activity is expected, with daily totals ranging from 15 to 25 mm across much of the region. Isolated thunderstorms could contribute an additional 10 to 20 mm per day over the next four days. The cumulative five‑day rainfall totals could exceed 75 mm in the Upper Thames River Conservation Authority (UTRCA) watershed.
Ground conditions are near saturated from last week’s rainfall and water levels remain slightly elevated. Much of the forecast rain will run off into local water bodies, should it materialize, raising water levels as the week progresses to close to, or higher than, what was experienced last week.
The UTRCA does not expect serious flooding at this time but will be watching this event closely and providing updates to this message if conditions change. The UTRCA will be operating its flood control reservoirs at Fanshawe, Wildwood, and Pittock Conservation Areas to reduce downstream flooding.
The public is reminded to use extreme caution near all local waterways. Stream banks may be slippery and unstable, and the water is very cold and fast-moving. Stay out of any flooded areas and do not drive through flooded roadways. Caregivers are reminded to keep children and pets away from watercourses. It is not safe to take shelter along riverbanks or in low lying areas that are prone to flooding.
