Special Weather Statement Issued for Eastern Ontario: Significant Rainfall Expected

Tuesday, May 6, 2025 — At 1:20 p.m., Environment Canada issued a Special Weather Statement for parts of eastern Ontario, warning of the potential for significant rainfall beginning tonight through Wednesday morning.

Rainfall totals are expected to range between 30 and 50 mm, with some localized areas possibly exceeding that amount due to slow-moving showers and thunderstorms.

Residents in low-lying areas are advised to remain vigilant, as localized flooding is possible. For updates regarding flood risks, the public is encouraged to check with local Conservation Authorities, the Ontario Ministry of Natural Resources, or visit Ontario.ca/floods.

Environment Canada urges the public to monitor forecasts and alerts and report severe weather by emailing onstorm@ec.gc.ca or posting on X (formerly Twitter) with the hashtag #ONStorm.
