Periods of heavy rainfall associated with the remnants of Hurricane Beryl will affect parts of southern Ontario starting tonight or Wednesday morning. While confidence in the exact track of the weather system is still somewhat uncertain, these types of systems have historically produced very high rainfall amounts in downpours.

Rainfall amounts are likely to vary widely across the region, with some areas receiving more than 60mm. Conditions are expected to improve on Thursday.

For flood information, contact your local Conservation Authority or the Ontario Ministry of Natural Resources and Forestry office. Visit Ontario.ca/floods for the latest details.

Heavy downpours may cause flash flooding and puddles on roads. Localised flooding in low-lying areas is possible.

If visibility is poor while driving, slow down, watch your tail lights, and be prepared to stop.
