The severe storms have caused widespread disruptions, including power outages, flight cancellations, and public transit delays. The hardest-hit areas include west and northwest suburbs, with tree limbs down and streets flooded. Heavy rainfall may lead to localized flooding, and damaging winds pose risks to outdoor activities. Residents are advised to stay indoors during the storms and avoid flooded areas. The heat advisory adds further risks, particularly for vulnerable populations, with cooling centers available for relief.
