Residents of Port Colborne can expect a wet and windy week as Environment Canada forecasts rain and gusty conditions to impact the area through May 11, 2026. Showers are expected to begin this afternoon, accompanied by southwest winds gusting up to 60 km/h.
The rain is expected to persist through Tuesday night, with an accumulation of 10 to 15 mm, and continue into Wednesday before clearing.
