Environment Canada has issued a rainfall warning for Burlington, Ontario, on Wednesday, March 11, 2026. The city is expected to receive between 20 and 40 mm of rain today, with higher amounts possible if thunderstorms develop.
Weather experts are concerned about flooding because the ground is currently frozen or already soaked, which prevents it from soaking up the rain. As a result, water is expected to pool on local streets and in low-lying parts of the community.
The weather will change quickly as temperatures drop from an unseasonably warm high of 15°C today to -4°C overnight. This sharp cooling could cause standing water on the roads to freeze rapidly, creating slick and hazardous conditions for anyone traveling late at night or early tomorrow morning.
Residents should avoid driving through flooded areas and watch for high wind gusts that could make travel more difficult. Local officials advise keeping an eye on the forecast as the heavy rain turns into freezing temperatures and potential flurries.
