Thunder Bay issues heavy rainfall warning: up to 50 mm expected

Environment Canada issued an alert on the evening of the 27th, forecasting that a heavy rainfall system will arrive in Thunder Bay on Monday afternoon and may last into the evening. Estimated cumulative rainfall is 30-50 mm, with a risk of localized ponding and even flash flooding in low-lying areas. The ground is still partially frozen, reducing its ability to absorb water. Residents are reminded to clear drains promptly, avoid driving through water, and monitor subsequent weather updates.
