Emergency responders received over 30 requests for assistance related to flooded basements and performed 16 water rescues to help affected residents.
Beyond residential impacts, significant property damage was reported, including the collapse of a basement wall on Detweiler Avenue. The Mount Joy Borough Authority also had to respond to a sewage backup situation, which involved dislodged manhole covers as the stormwater system struggled to cope with the sheer volume of rain.
As recovery efforts begin, local officials are urging residents who have experienced property damage to report their situations through designated local channels. Two debris disposal events are scheduled for July 18 and July 19, allowing community members to dispose of debris safely.

Flash flood warnings were in effect for Lancaster and York counties until 7 p.m. on Monday, and ongoing thunderstorms were anticipated to exacerbate conditions. The National Weather Service also issued flood watches for multiple counties, including Perry, Franklin, and Cumberland, highlighting the continued risk of flooding in the broader region.
As the afternoon turned to evening, emergency services remained on high alert as the rain continued to fall, prompting further monitoring of water levels and swift responses to emerging situations.
