On Sunday evening, the National Weather Service issued a flash flood warning for Onondaga County, in effect from 7:17 p.m. until 10:15 p.m. Doppler radar indicated thunderstorms producing heavy rain, leading to ongoing or imminent flash flooding.
The warning impacts various locations, including Syracuse, Manlius, and Lyndon. Residents are urged to take immediate action, especially in flood-prone areas, by moving to higher ground. The weather service stresses the critical safety message: "Turn around, don't drown" when encountering flooded roads, as the majority of flood-related fatalities occur within vehicles.
