Duluth, Minn. – Flash flooding is possible across northeastern Minnesota and northwest Wisconsin late Sunday as several rounds of torrential thunderstorms are set to hit already saturated ground.
According to the National Weather Service in Duluth, a Flood Watch is in effect from 4 p.m. Sunday through 6 a.m. Monday for 13 counties including St. Louis, Cook, Carlton, Pine, and Aitkin in Minnesota, and Douglas, Bayfield, Burnett, and Washburn in Wisconsin. Low-lying areas, creeks, and urban drainage zones are especially vulnerable to fast-developing floods.
The affected area includes major roadways such as I-35 near Hinckley, Highway 53 near Duluth, and parts of the Apostle Islands National Lakeshore. Heavy rain may also impact tribal lands like the Fond du Lac Band and Red Cliff Band reservations.
Residents should avoid flooded roads, monitor alerts closely, and be prepared to seek higher ground if a Flash Flood Warning is issued. Charge devices, keep emergency kits ready, and check in on vulnerable neighbors, especially in rural or low-lying areas.
More rainfall could push streams beyond capacity, especially near the St. Louis River and Kettle River basins.
Flood Watches remain active until Monday morning. Additional alerts may be issued overnight if storm activity intensifies.
