At least 5 dead in Indiana's worst flooding in 30 years as severe storms batter Midwest and Northeast

A wave of severe storms struck multiple U.S. regions, spawning confirmed tornadoes, flooding, and at least one siren failure.

A multi-day severe weather pattern stretching from the Midwest to the Northeast has caused significant damage, deaths, and prolonged power outages across the region. In Indiana, at least five people have died amid what officials describe as the worst flooding in over 30 years. The National Weather Service reported more than 11 inches of rain fell in some areas over a two-day period. Tens of thousands of Indiana residents are now entering a ninth day without power after the deadly storm toppled trees and power lines. Schools remain closed and businesses have been unable to reopen, compounding the humanitarian toll. In Delaware, Dover declared a state of emergency after a confirmed tornado touched down Thursday night, causing significant damage to the city. In the New York metro area, rounds of heavy rain and damaging winds triggered flash flood and tornado warnings across parts of New York City and the broader Tri-State region. On Long Island, a possible tornado touched down in Atlantic Beach, with heavy rain slowing traffic across the area. In Wisconsin, West Allis residents faced a separate public-safety concern: when a tornado warning was issued Tuesday night, the city's outdoor warning sirens never sounded. Milwaukee County's Office of Emergency Management confirmed the silence was due to an equipment failure, prompting community concern about preparedness gaps. Indiana's death toll and extended power outages represent the most severe human impact reported across this storm system so far.

Why it matters

Confirmed tornadoes and widespread flooding across multiple states put lives and property at risk, while the West Allis siren failure highlights a potential gap in emergency alert systems that communities depend on during fast-moving severe weather.

What's next

Milwaukee County's Office of Emergency Management has not yet publicly stated when the failed sirens will be repaired or what caused the equipment malfunction.

Key facts

• Dover, a city, declared a state of emergency after a confirmed tornado touched down Thursday night
• A possible tornado touched down in Atlantic Beach on Long Island during the Tri-State storm event
• Flash flood and tornado warnings were issued for parts of New York City and surrounding Tri-State area
• Tornado warning sirens in West Allis failed to activate during Tuesday night's severe weather
• Milwaukee County's Office of Emergency Management confirmed the West Allis siren silence was caused by an equipment failure
• Severe weather events were reported across multiple regions, from Wisconsin to the mid-Atlantic, within the same week

Bias & framing notes

These four sources cover four distinct but related storm events, only loosely connected by the same broad severe weather pattern — they are not all reporting on a single incident. The West Allis siren failure story (TMJ4) is the most locally specific and adds a public-safety accountability angle absent from the other reports. ABC7 and Newsday focus on the New York metro area with overlapping geography but separate incidents. The 6abc Philadelphia report on Dover is the only one confirming a state of emergency, making it the most consequential single event reported, yet it receives no corroboration from a second source here. No source provides casualty figures or damage cost estimates.
