MINNEAPOLIS — Severe thunderstorms on April 13, 2026, generated large hail and at least three confirmed tornadoes across central and southern Minnesota, causing property damage and localized flooding in Wisconsin.
The National Weather Service (NWS) reported hail up to 3.5 inches in diameter in central and southern Minnesota. Preliminary damage assessments indicate an EF-1 tornado with 90 mph winds tracked east from near Truman to Amboy. Additional tornadoes were reported west of Elmore and southeast of Matawan. Damage included blown-out garage doors, outbuildings lifted off foundations, and extensive tree damage, according to NWS reports. Heavy rainfall associated with the storm system also led to localized flooding in parts of Wisconsin.
For restoration contractors, homeowners, and insurance adjusters, these events signal an immediate need for damage assessment and mitigation. The combination of large hail and tornado-force winds often results in complex structural damage, roof compromise, and water intrusion. Homeowners should document damage thoroughly for insurance claims, while contractors will focus on securing properties and preventing secondary damage from water or further weather exposure. Insurance adjusters will be evaluating claims for both wind and hail damage, which can sometimes present distinct challenges in assessment.
Emergency management officials across affected counties are continuing damage assessments. The NWS noted that the preliminary EF-1 tornado near Truman and Amboy is subject to further review as ground surveys are completed. The widespread nature of the hail events, particularly the large stone sizes, suggests a significant volume of property damage claims related to roofing, siding, and vehicle impacts. Localized flooding in Wisconsin will require attention to water extraction and structural drying in affected areas, adding another layer of complexity to the overall recovery effort.
Further updates on storm damage and recovery efforts are anticipated as emergency management agencies complete their assessments. Property owners affected by the storms are advised to contact their insurance providers and licensed restoration professionals promptly. Official resources for disaster assistance and damage reporting are available through local emergency management offices and the National Weather Service.
