Residents in the Susquehanna Valley should prepare for potentially hazardous weather conditions. The combination of high humidity and temperatures could lead to heat-related illnesses, especially for those spending extended periods outdoors. The evening storms may bring damaging wind gusts, heavy rainfall, and localized flash flooding, with small streams and creeks at risk of overflowing. Isolated large hail is also possible. Drivers are advised to avoid flooded roads and remain cautious during storm activity.
