Low pressure tracked up the east coast and interacted with a stalled frontal boundary and approaching upper level low pressure system. Strong southerly flow allowed for the transport of tropical moisture, including the remnants of Tropical Storm Nicole, up the coast which resulted in heavy rain and flooding in portions of New York City, Nassau and Rockland Counties.
