The severe weather poses significant risks to densely populated areas along the I-95 corridor, including New York City, New Jersey, and eastern Pennsylvania. Flash flooding is a major concern, especially in areas with already saturated soil, where even one inch of rain over six hours could lead to rapid runoff. Damaging wind gusts, large hail, and isolated tornadoes are also possible, particularly in western New York and eastern Pennsylvania. Air travel disruptions are widespread, with passengers advised to check flight statuses due to ongoing ground delays. Road travel is also impacted, with incidents like a bus rollover reported in Ulster County, New York.
