More than 38 million people across the Northeast, from New York City to Washington, D.C., are preparing for severe weather on Thursday. The forecast includes the possibility of flash flooding, damaging winds, large hail, and isolated tornadoes.

The threat encompasses a broad region, extending from Syracuse, New York, and Vermont southward into Virginia. This widespread outlook means a significant portion of the densely populated Northeast corridor is at risk for hazardous conditions.

For the critical Interstate 95 corridor between New York City and Washington, D.C., forecasters predict heavy thunderstorms capable of producing rainfall rates exceeding 2 inches per hour. Some areas could see total accumulations reach up to 5 inches.

The storms are expected to begin around 1 p.m. on Thursday, continuing in a scattered pattern through the afternoon and evening. New York City is likely to experience the most intense storm activity between 1 p.m. and 5 p.m., with Philadelphia and Washington, D.C., facing the peak between 5 p.m. and 8 p.m.

A flood watch has been issued for New York City, its Hudson Valley region, much of New Jersey, and Philadelphia, effective from noon through the evening hours. This indicates a heightened risk of localized flooding due to the anticipated heavy rainfall.

Residents and authorities are advised to monitor weather updates closely as the situation develops. The potential for rapid flooding poses a significant risk to transportation and infrastructure in affected urban and suburban areas.

Details regarding the specific timing and intensity of the storms are subject to change as meteorological models refine their predictions. The National Weather Service will provide updated advisories as necessary.

This forecast highlights the volatile nature of summer weather patterns in the region, underscoring the importance of preparedness for severe weather events.
