A slow moving area of low pressure brought periods of steady rain to western New York. Embedded thunderstorms within the steadier rain caused heavier downpours at times during the evening on May 5th. Heavier rain, combined with the periods of steady rain resulted in Flash Flooding in Allegany and Livingston counties. The Town of Canaseraga experienced the brunt of the flooding.
