According to the National Weather Service in St. Louis, survey teams confirmed an EF-0 tornado in Marine at 1:41 p.m. with 76 mph winds and a short 0.33-mile path, followed by two EF-1 tornadoes during the evening. The Mascoutah to Trenton tornado tracked 9.65 miles from 7:53 p.m. to 8:03 p.m., while a second EF-1 from Germantown to Carlyle traveled 11.66 miles between 8:06 p.m. and 8:18 p.m.
Damage included downed trees, minor structural impacts and debris on roadways, particularly near Mascoutah, Germantown, Carlyle and Trenton. Brief blockages were possible along I-64 and nearby local roads where debris and tree limbs fell, creating short-term travel hazards during and immediately after the storms.
The tornadoes developed as part of a broader system bringing strong instability and rotating thunderstorms into the region Monday evening, allowing brief but organized tornado formation.
Drivers should watch for remaining debris on rural roads and avoid damaged areas as cleanup continues, while residents should report additional damage to local officials.
The most significant impacts occurred between 7:53 p.m. and 8:18 p.m. Monday, when the two EF-1 tornadoes caused the longest damage paths and greatest disruption
