Rainfall amounts will likely be highly variable across the region, and some areas may receive in excess of 80 mm. Rain will taper to scattered showers from west to east tonight through early Thursday morning.
For information concerning flooding, please consult your local Conservation Authority or Ontario Ministry of Natural Resources and Forestry office. Visit Ontario.ca/floods for the latest details.
Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.
If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop. Watch for possible washouts near rivers, creeks and culverts.
