Environment Canada issued a yellow warning - severe thunderstorm for Montreal, Laval and parts of the South Shore at 1:25 p.m. The warning covered a wide stretch of the Montreal area as meteorologists tracked a storm capable of damaging wind gusts, quarter-size hail and heavy rain.
Environment Canada told people in the warning area: “Take immediate cover if a thunderstorm approaches. If outside, protect yourself from flying debris and hail.” That advice pointed to the practical step residents could take right away: get indoors before the storm reaches their location.
Montreal And Laval Coverage
The warning applied to Montreal, Laval and parts of the South Shore, placing multiple municipalities under the same yellow-coded alert. For people moving between those areas, the warning meant the storm could affect a broader part of the region rather than a single neighborhood.
Meteorologists said they were tracking a severe thunderstorm with three main hazards: damaging wind gusts, quarter-size hail and heavy rain. Those are the conditions most likely to interrupt outdoor plans and make travel more difficult during the warning window.
Environment Canada Warning
The yellow-coded warning was issued at 1:25 p.m., giving residents a specific time to check conditions before the storm arrived. Environment Canada’s wording focused on immediate shelter and protection from hail and flying debris, which is the clearest action available to anyone caught outdoors.
For readers in Montreal, Laval and the South Shore, the next step was straightforward: move under cover quickly if thunder was approaching and avoid remaining outside once the storm neared. The warning itself centered on the current threat, not a later forecast update, so the immediate concern was the storm already being tracked over the region.
