Rainfall Warning

Issued at 04:24 Tuesday 20 February 2018

Rainfall, combined with melting snow, continues.

Significant rainfall continues until Wednesday morning.

Several rounds of rain will continue today and tonight giving rainfall amounts of 25 to locally 40 mm by Wednesday morning. Since very mild conditions are accompanying the rain, considerable snowmelt is anticipated. As a result, localized flooding is likely in low-lying areas.

This wet, record mild spell is attributed to a series of low pressure systems moving along a warm front draped across the lower Great Lakes. A final band of rain is likely along a cold front Wednesday, bringing the rain to an end. However, multi-day rainfall totals in the 30 to 50 mm range are likely in some areas.


Localized flooding in low-lying areas is possible.

Rainfall warnings are issued when significant rainfall is expected.

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