Chicago Area Braces for More Severe Weather After Tornadoes Strike LaSalle County The Chicago metropolitan area is preparing for additional severe weather on Tuesday as the region continues to recover from two tornadoes that struck LaSalle County on Sunday night and Monday morning. Emergency officials reported that the storms caused widespread damage, including downed trees, power outages, and flooding, while residents and crews worked to clear debris and assess the impact of the weekend storms. The National Weather Service issued updated alerts for severe weather, with a heightened risk of storms expected to intensify on Tuesday. The tornadoes that hit LaSalle County were confirmed as EF1 events, with peak winds reaching up to 100 mph. One tornado struck Ransom, Illinois, approximately 90 miles outside Chicago, while another touched down near Streator, leaving EF1 damage in its wake. A third tornado was reported east of Amboy in Lee County, with maximum estimated winds of 90 mph. The National Weather Service confirmed the tornadoes, noting that the storms were part of a larger weather system that brought multiple rounds of severe thunderstorms to the region. Cleanup efforts are ongoing in several neighborhoods affected by the storms. In Andersonville, a tree fell on parked cars near Catalpa Avenue and Clark Street on Monday morning, prompting crews to remove debris by midday. Residents expressed concern over the frequency of severe storms this summer, which has led to repeated incidents of property damage. In Oak Lawn, road flooding forced drivers to navigate slick conditions, with one car reportedly entering a retention pond in Mundelein. A separate incident in Bartlett saw a lightning strike ignite a tree, damaging an underground natural gas main and sparking a fire.#national_weather_service #chicago_metropolitan_area #lasalle_county #ransom_illinois #streator
