Deadly tornado outbreak threatens Northeast with hail, flooding, power outages

A deadly severe-weather system that ripped through the Midwest is now aiming at the Northeast, carrying the risk of dangerous thunderstorms, large hail, damaging winds, power outages and scattered flooding. The same multiday outbreak has already produced more than 50 reported tornadoes, killed three people and left some neighborhoods flattened in Illinois and northwest Indiana.

The National Weather Service said that as of June 22 there were at least 51 tornadoes tied to the June 11 outbreak in the region, including 6 rated EF-2 or stronger. NWS Chicago later said the regional total had climbed to at least 57 tornadoes, with 23 in its warning area alone, making it the second-largest tornado outbreak on record there, behind July 15, 2024. During the outbreak, the Storm Prediction Center logged more than three dozen tornado reports as a cluster of supercell thunderstorms moved east.

The hardest-hit corridor ran through Illinois, Indiana, Wisconsin and Michigan, where strong tornadoes caused major structural damage and knocked out power to hundreds of thousands of customers. In parts of Illinois and northwest Indiana, media reports described flattened structures and neighborhoods stripped bare. CBS News reported that the Chicago area briefly faced a level 4 out of 5 severe-risk designation, a rare high-end forecast level typically seen only about once every two years.

The broader severe-weather siege stretched from June 7 through at least June 12, sweeping from the Central Plains through the Midwest, Great Lakes and Ohio Valley and into the Northeast. Weather.com said the system generated more than 1,700 storm reports over that stretch, while iAlert Weather counted 2,392 storm reports across 41 states from June 10 through June 12 alone. Those totals underscore the scale of the outbreak: not just a line of storms, but a wide regional emergency that combined tornadoes, damaging winds, hail and significant flooding.

Now the storm threat is shifting toward major Northeast cities. Forecasters warned that Philadelphia, New York City and Washington could face heavy rain, power outages and localized flooding as the system moves on. The geographic chain reaction from the Midwest to the Northeast shows how one prolonged outbreak can strain warning systems, utility crews and emergency planners across multiple regions at once.
