Binghamton, N.Y. – Flash flooding and triple-digit heat index values threaten Central New York this afternoon as tropical moisture collides with a slow-moving cold front. Cities along the I-81 corridor—especially from Syracuse to Binghamton—could see storms with up to 3 inches of rain and damaging winds by late evening.
According to the National Weather Service in Binghamton, storms will begin forming between 1 p.m. and 2 p.m. Monday, with the greatest rainfall and flood risk west of I-81. A Heat Advisory remains in effect until 8 p.m. for areas including Ithaca, Elmira, and Cortland, where heat index values are expected to reach or exceed 100°F.
Localized flash flooding is most likely near Steuben, Chemung, and Broome counties, where repeated thunderstorms could dump heavy rain in short bursts. Isolated wind gusts could down trees or power lines. Residents are urged to avoid flooded roadways and charge devices ahead of potential outages.
The storm system is expected to stall just south of the region Tuesday, continuing flood risks into the Catskills and Northeast Pennsylvania. Another round of storms is possible during Tuesday’s afternoon heating.
⚠️ Warnings remain in effect through Monday night. Additional watches are possible Tuesday.
