The Niagara Peninsula Conservation Authority (NPCA) is advising the public and local municipalities of the potential for flooding within its jurisdiction late Wednesday June 17 into Thursday June 18, 2026. This includes the Niagara Peninsula, the southeastern portion of the City of Hamilton, and the eastern portion of Haldimand County. The Niagara Peninsula Watershed is currently under a Special Weather Statement, with forecasted rainfall up to 40 mm or greater with the risk of severe thunderstorms moving into the area this evening near midnight. These storms may also produce gusts of 70 to 90 km/h with heavy downpours of rain of up to 20 mm/hour in some locations. Some watercourses are still draining the precipitation/runoff from the storm this past Sunday and are expected to respond rapidly to these rainfall amounts and intensities. While the NPCA does not anticipate major flooding along larger watercourses, nuisance flooding in low-lying areas adjacent to smaller streams and creeks is likely. This notice remains in effect until 9:00 AM on Friday, June 19, 2026, and will be updated as conditions warrant.
