Impact & Risks
Flash flooding poses a significant risk to urban areas along the I-95 corridor, including Washington, D.C., Philadelphia, and New York City. The storms could lead to rising water levels in streets, creeks, and streams, especially in densely populated regions. The risk is heightened by the possibility of two rounds of storms, one midday and another between 5 p.m. and 8 p.m. Residents in flood-prone areas should remain vigilant as rainfall rates may exceed 1 inch per hour, increasing the likelihood of flash flooding.
