Environment Canada issued a warning on June 21, 2026 that the Montreal area and surrounding parts of southern Quebec could see another round of rain and storms after the flash flooding that struck the region on Saturday evening. The agency said atmospheric conditions are now aligned in a way that makes a repeat of the recent severe weather possible, prompting officials to alert residents to the heightened risk.

The warning follows the flash flooding that left many communities in the southern part of the province dealing with water damage and disrupted services. Emergency crews are still working to clear debris, restore power, and assist those affected by the sudden rise in water levels that occurred Saturday night. While the current alert does not specify exact timing, it emphasizes that the same weather patterns that caused the earlier event remain in place.

Environment Canada noted that the combination of moisture-laden air and favorable wind patterns could generate additional rainfall over the coming days. Residents in the Montreal metropolitan area and nearby municipalities are advised to stay informed about evolving conditions and to be prepared for possible localized flooding if the forecast materializes.

Authorities in the region have urged people to monitor local weather updates and to avoid traveling through low‑lying areas that could become inundated. The agency also reminded the public that repeated storms can compound damage to infrastructure, making it important for communities to remain vigilant until the situation stabilizes.

As the area continues to recover from Saturday’s flash flooding, the new warning serves as a reminder that the weather threat has not fully passed. Officials will continue to assess conditions and issue further guidance as needed, aiming to minimize additional impact on residents and critical services.
