As the system intensified, a confirmed tornado near Union City was reported by the National Weather Service around 4:43 p.m. local time, indicating a broad, dangerous tornado outbreak in southwest Michigan.

Authorities confirmed multiple fatalities in Branch and Cass counties, along with injuries and widespread destruction to homes and structures.

A deadly tornado event on March 6, 2026, in southern Michigan caused at least four deaths and twelve injuries across Branch and Cass counties, with damage extending from Edwardsburg to Union City and Three Rivers.

Forecasts warned of additional thunderstorms with possible hail and damaging winds for Saturday, with temperatures in the Detroit area reaching near 68°F and a low around 38°F.

The outbreak arose from a powerful storm system that triggered tornado warnings from the National Weather Service offices in Grand Rapids and northern Indiana, with a path estimated at about 50 miles.

Officials urged people to seek shelter as severe weather persisted overnight, potentially delaying damage assessments and surveys.

Numerous hail reports were gathered from the affected areas by NWS officials.

A series of tornado reports flooded in Friday afternoon around Three Rivers, starting with a 3:11 p.m. touchdown in Edwardsburg and continuing through 3:46–3:52 p.m. with multiple sightings and a damaging roof impact at a Menards store, signaling a large, dangerous tornado path through Cass, St. Joseph, and Branch counties.

Storm chasers and emergency personnel documented at least four tornado events centered in Three Rivers within a short window, including ground-tornado sightings near the Three Rivers Waste Management facility and other nearby areas.

NWS researchers planned storm surveys across Cass, St. Joseph, and Branch counties to assess damage, with survey start times influenced by morning weather and potential overnight showers.

In total, eight tornado reports were logged within roughly 90 minutes in southwest Michigan, prompting formal NWS investigations.

The aftermath featured downed trees, damaged homes, and a Menards store in St. Joseph County, with extensive damage across southwest Three Rivers, leading to planned meteorology surveys to gauge intensity and confirm the number of tornadoes.
