July 23-26, 2018 Flooding Event

Overview

On July 24-25th, 2018, a slow-moving frontal boundary moved through Pennsylvania, bringing heavy showers and thunderstorms and causing widespread flooding across the state. Rainfall totals across the state over the 4-day period (nearing a foot in some locations) were so high that multiple cities achieved their wettest July on record.

Muddy brown floodwaters in Spring Creek flow beneath the Skyrush roller coaster, painted yellow, and the Comet roller coaster at Hershey Park in Hershey, Pa. The park closed Monday and Wednesday this week.
