were recorded. Elsewhere, or more of precipitation fell throughout parts of Pennsylvania, New Jersey, New York and Connecticut. At least 22 states received rainfall from Hurricane Eloise and its remnant moisture. Nearby Hurricane Faye may have also contributed to the heavy rainfall, although this connection was never confirmed. In Washington, D.C., of rain contributed to the wettest September on record since 1934. The excessive rainfall led to extensive flooding throughout the region, in some areas exceeding 50- to 100-year levels. Pennsylvania and New York bore the brunt of the flooding, which culminated in loss of life and severe property damage. Along the central Southern Tier region of New York, the storm damaged or destroyed over 700 structures. Flooding throughout the Northeastern United States disabled over a dozen water plants and at least 16 sewage treatment plants, prompting a boil-water advisory in Pennsylvania's capital city of Harrisburg. Infrastructure further south also suffered; in Maryland, the Monocacy River—a tributary of the Potomac—swelled to above flood stage, inundating the city of Frederick and compromising the city's supply of fresh drinking water. A final downpour of rain on the night of September 25–26 led to an additional of rain in central Maryland triggered severe flash flooding. In some cases, this onslaught affected the same areas that were still recovering from Hurricane Agnes several years earlier, including Ellicott City, Elkridge, and Laurel, where two major rivers breached their banks and engulfed nearby areas. Many homes and businesses were lost, along with numerous vehicles; in the aftermath, looters entered on boats to access the devastated cities. The floodgates at the Rocky Gorge Dam in Laurel were opened, forcing 500 residents downstream to leave their homes. The consequences of the flooding rains were the worst seen in areas of the interior Mid-Atlantic states since Agnes, and comparisons were often drawn between the two hurricanes. In Pennsylvania alone, flooding from the remnants of Eloise forced 20,000 residents out of their homes; thousands further south in the Washington, D.C. area, where severe flooding impacted the city's southern suburbs, also fled to seek refuge. Further, many motorists throughout the region became stranded on highways inundated by floodwaters. Four Mile Run and nearby streams overflowed and "tumbled through residential neighborhoods". Hundreds of families in the Alexandria and Arlington, Virginia area suffered flood-related losses. Across the Northeastern U.S., the storm system killed 17 people and inflicted $300 million in damage. An instance
