Residents in Burlington should prepare for wet conditions and the potential for storms as a weather system moves through the region starting Tuesday, May 5, 2026. While Environment Canada reports there are no active weather alerts currently in effect for the city, the forecast indicates a shift toward periods of rain throughout Tuesday afternoon and continuing into Wednesday.
According to The Weather Network, southern Ontario is facing a risk of nocturnal thunderstorms from Tuesday night through Wednesday morning. These storms could bring frequent lightning, heavy downpours, and the possibility of hail. Rainfall totals across the Greater Toronto Area are expected to reach between 20 and 30 mm as the system passes.
Officials are advising caution due to the current state of the ground. Because the soil is already saturated, it has a reduced capacity to absorb more water, which increases the likelihood of pooling on roads and in low-lying areas. Drivers are encouraged to exercise care on potentially slick surfaces, and residents should keep an eye on outdoor furniture or other items that could be affected by the weather.
The unsettled weather is expected to clear by Thursday, May 7, 2026, which is forecasted to be a sunny day. However, temperatures will see a significant drop, with a high of 11°C during the day and an overnight low near -1°C.
