Duluth, Minnesota – Drivers and residents across northern Minnesota should prepare for a surge of severe weather, with storms capable of producing hail, damaging winds, and heavy rain expected along and north of Highway 2 through Wednesday morning.
According to the National Weather Service in Duluth, rain will continue overnight, intensifying Tuesday afternoon and evening as thunderstorm activity increases. Scattered severe storms may develop, bringing primary hazards of hail and wind, with heavy rainfall raising flash flooding concerns—especially from International Falls through Grand Rapids and the Iron Range. An isolated tornado cannot be ruled out Tuesday night.
Travelers on Highway 2 and area roads should watch for localized flooding, especially in low-lying areas and spots with poor drainage. Utility outages and hazardous driving are possible as storms move through. Residents are advised to secure loose outdoor items, avoid travel during severe weather, and have multiple ways to receive weather alerts. If flooding occurs, never drive through water-covered roads.
This is the most significant storm threat northern Minnesota has seen since early June, with rainfall totals of 1–2 inches likely, and locally higher amounts possible.
Severe weather watches and warnings may be issued with little notice.
Stay tuned: The risk of flash flooding and strong storms will persist through Wednesday morning, with updates expected from the National Weather Service.
