Syracuse, N.Y. – Slow-moving thunderstorms are expected to drench parts of central and southern New York beginning Tuesday afternoon, with flash flooding possible from Syracuse through Binghamton and into the Finger Lakes by early Wednesday.
According to the National Weather Service in Binghamton, a Flood Watch is in effect from 2 p.m. Tuesday through Wednesday afternoon for counties including Onondaga, Broome, Chemung, Tioga, and Tompkins. The alert also covers parts of northeast Pennsylvania, including Bradford and Susquehanna counties.
The heaviest rain is forecast to fall Tuesday evening as thunderstorms develop along an upper-level low pressure system. These storms may repeatedly pass over the same areas—a phenomenon known as “training”—increasing the risk of rapid flooding. Creeks, small rivers, and poor-drainage zones are most vulnerable, especially in urban areas like Elmira, Ithaca, and Cortland.
Drivers should avoid flooded roads and remain alert for rising water, particularly near Route 17, I-81, and low-lying rural roads. Residents are urged to charge devices, monitor weather alerts, and have a go-bag ready in case evacuation becomes necessary.
Rain may linger into Wednesday morning, especially across the Finger Lakes and Syracuse region. Additional warnings could be issued overnight if flash flooding intensifies.
