The primary risks include flash flooding, particularly in urban areas like Houston, where intense rainfall could overwhelm drainage systems. Severe storms on Wednesday and Thursday pose threats of damaging winds, large hail, and tornadoes, potentially impacting major cities such as Kansas City, Chicago, and New York City. Power outages, property damage, and travel disruptions are likely in the affected regions. The tropical disturbance driving the rainfall could exacerbate flooding risks, especially in low-lying areas.
