Danny was reported to have become absorbed by an extra-tropical depression over North Carolina early on August 29, 2009. The National Hurricane Centre (NHC) reported that at 09:00 UTC on 29 August, the remnants of Danny were located around 80 miles (130 kilometers) southeast of Cape Hatteras, North Carolina and around 540 miles (875 kilometers) south-southwest of Nantucket, Massachusetts. As of 09:00 UTC on August 29, the tropical storm watch for the North Carolina coast from Cape Lookout northward to Duck, including the Pamlico and Albemarle sounds, had been discontinued.
The NHC forecasted the extra-tropical low to move rapidly towards the north-northeast and then northeast at around 30 mph (48 kmph) during the course of the August 29 to August 30. The NHC advised that large swells from the extra-tropical low were expected to produce dangerous surf conditions and life-threatening rip currents along the U.S. east coast during the course of the weekend. According to reports, New England and the Canadian Maritime provinces of Nova Scotia and New Brunswick were warned to monitor the progress of the low-pressure system as it moves northward.

Contrary to earlier expectations, Danny did not reach hurricane status on its approach to the U.S. east coast. Although no damage has been attributed to Danny, reports said that the heavy rain combined with dangerous currents emptied beaches on the U.S. east coast for a second consecutive weekend. As of August 30, a flood watch remained in effect for parts of Massachusetts following the heavy rain. Beaches were also ordered to remain closed and ferry services in and around Boston were cancelled.
Elsewhere in New York’s Long Island, Nassau County’s health department reportedly closed 20 beaches on Sunday due to the heavy rainfall. The storm water runoff from the passing remnants of Danny had the potential to cause sewage discharges and elevated bacteria levels along the Long Island sound.
