Residents in western and north-central New York, including Buffalo, Rochester, and the Finger Lakes, should prepare for damaging winds and heavy rainfall. Flash flooding is a significant concern, particularly in low-lying and poor-drainage areas. Roads may experience water ponding, and small streams and creeks could rise rapidly. The storms may also disrupt travel and outdoor activities, especially near Lake Erie, Lake Ontario, and the St. Lawrence River. The risk of severe weather is highest Monday evening into the overnight hours, with continued flooding risks through Wednesday.
