Where: Lancaster forecast zone
Reported by: EMERGENCY MANAGER

Heavy rain caused flooding in Lancaster county during the evening of June 17. Minor flooding began during the late afternoon, but more significant flooding began around 10 pm. Several roads were closed in the city of Lancaster. In addition, flooding forced the closing of Manheim Pike in Manheim Township north of Lancaster, and Mount Joy Road in Rapho Township.
