EF-3 Tornado Confirmed in Porter County, Indiana. Streator, Illinois Also Hit Hard as Storm Cleanup Enters Second Day.

Since Thursday's outbreak brought tornadoes across eight states and killed one person in Iowa, the damage picture in Illinois and Indiana has sharpened considerably through Friday morning.

The National Weather Service confirmed to NBC Chicago that an EF-3 tornado struck Porter County in northwest Indiana during Thursday's storms. EF-3 is the fourth step on the six-point Enhanced Fujita scale, associated with wind speeds between 136 and 165 mph and capable of leveling well-constructed homes.

Streator and Merrillville

In Illinois, drone footage obtained by NBC Chicago shows a wide debris field across Streator, a city of roughly 11,000 in LaSalle County about 90 miles southwest of Chicago. NBC Chicago reporter Jenn Schanz described the Streator damage in video coverage as a "complete wake of destruction." A separate suspected tornado hit Merrillville, Indiana, where NBC Chicago correspondent Jorge DeSantiago reported residents describing their homes as a "complete loss."

AP News reported Friday that officials in both states are actively searching tornado-damaged areas and that cleanup efforts are underway as of June 12. No additional fatalities beyond Thursday's Iowa death have been confirmed in Illinois or Indiana based on available sourcing.

AP News' available text focused primarily on the ongoing search and recovery framing but did not include specific EF-scale ratings or community-level damage breakdowns for Illinois and Indiana—details that NBC Chicago's local coverage provided. Neither source has published confirmed injury tallies specifically for the Illinois and Indiana tornadoes as of this writing.

Residents and local officials in Porter County and LaSalle County have a legitimate grievance about warning lead times and shelter availability during fast-moving tornado outbreaks. When an EF-3 touches down in a densely populated suburban county like Porter, the margin between a bad night and a mass-casualty event is thin. Critics of the National Weather Service's current alert infrastructure argue that polygon-based tornado warnings, which replaced county-wide warnings in 2007, can still leave residents confused about whether they are inside the warning zone. That represents a real design tension in the system, not a fringe complaint.

The counterpoint is that Thursday's storms generated extensive advance coverage from Chicago-area meteorologists, and NBC Chicago published photos showing residents had largely cleared outdoor areas before impact. No mass-casualty event occurred in Illinois or Indiana, which suggests warnings were at least partially effective. The absence of deaths does not settle the question of whether alerting can be improved.

Illinois officials held a Friday update specifically on recovery resources, according to NBC Chicago, though the specific aid programs announced in that briefing were not detailed in available source text. Residents in affected counties in both states should monitor their county emergency management agencies for debris removal schedules and assistance applications.

As of June 12, formal EF-scale ratings for the Streator tornado and any other Illinois touchdowns have not yet been confirmed by the National Weather Service, per available sourcing. Porter County's EF-3 is confirmed; every other rating from Thursday's Illinois and Indiana storms is still preliminary. Those surveys typically conclude within 24 to 72 hours of an event, meaning official ratings for the remaining touchdowns could be released as early as Saturday.
