Overview

A deep plume of moisture along the East Coast of the United States developed on Thursday, the 30th of September. The moisture was associated with the remnants of Tropical Storm Nicole. This moisture was being drawn northward by a deep upper-level low pressure area over the eastern United States. The combined system produced a widespread heavy rainfall all along the East Coast, including Central and Eastern Pennsylvania.
