On March 11, 2026, Environment Canada issued a rainfall warning for Milton, Ontario, as a series of low-pressure systems are expected to bring significant rain to the region.
Forecasts show that between 20 and 40 mm of rain will fall throughout the day, with a risk of thunderstorms that could lead to even higher amounts in some neighbourhoods.
The primary concern for this weather event is that the ground remains frozen or soaked from the winter, which makes it difficult for the soil to absorb the new water.
Residents should expect to see water pooling on local roads and may experience minor flooding in low-lying areas during the storm.
Safety officials recommend that people avoid driving through flooded streets and stay away from areas known for poor drainage until the weather clears.
