Rainfall Warning

Issued at 10:56 Friday 31 March 2023

Rainfall, combined with melting snow, is expected.

Rainfall amounts of 20 to 40 mm.

Tonight into Saturday morning.

Two weather systems will affect the area over the next two days. The first will move through today bringing some snow or rain. Any snow will change to rain this afternoon or evening and become heavy overnight as a second and much stronger system begins to move in. The frozen ground has a reduced ability to absorb this rainfall. Total amounts of 20 to 40 mm are possible, particularly in areas that receive thunderstorms tonight.

For information concerning flooding, please consult your local Conservation Authority or Ontario Ministry of Natural Resources and Forestry office. Visit for the latest details.


Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #ONStorm.
