Thunderstorm wind is the defining hazard at Lower Delaware National Wild and Scenic River, with 13 recorded events logged for Bucks County — making it by far the most frequent danger families will face along this stretch of river. Those storms can arrive fast over open water, turning a calm afternoon paddle or riverside campsite into a serious situation with little warning.
When thunderstorms are in the forecast, get your canoe or kayak off the water and move well away from the riverbank before the front arrives — open water and tall riparian trees are both lightning and wind hazards. Pack a NOAA weather radio or download a radar app that sends storm alerts, since cell service along the river corridor can be spotty. Stake your tent with extra ground anchors and store loose gear inside your vehicle or a dry bag before turning in each night.

About Lower Delaware National Wild and Scenic River
