Special Weather Statement

Issued at 23:27 Monday 20 August 2018

Potential for heavy rainfall on Tuesday.

A few rounds of showers and thunderstorms are expected on Tuesday across portions of southern Ontario. The rain is expected to develop after midnight in southwestern Ontario and advance eastward to reach the Golden Horseshoe after daybreak.

The rain is expected to be periodic in nature with significant breaks from time to time. However, as the air mass will be very moist, torrential downpours giving significant rainfall amounts in relatively short periods of time are likely.

At this point, it appears that many areas will receive between 20 to 40 mm of rain by Tuesday evening. However, areas that get several thunderstorms may receive significantly higher amounts.


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