"Bye bye, Nadine. What a long, strange trip it's been."

That was the National Hurricane Center's farewell to Nadine, which has finally lost its closed circulation after its more than 22-day tour across the middle Atlantic Ocean.

Pending a post-storm analysis, Nadine will tie Ginger of 1971 as the second longest-lasting Atlantic tropical storm on record, at 21.25 days.

As a tropical cyclone, which includes the tropical depression stage, it is the fifth longest-lived cyclone on record in the Atlantic Basin, at 21.75 days.

The longest-lived tropical cyclone ever recorded in the Atlantic was a storm now known as the "San Cariaco Hurricane of 1899," which hung around for just shy of four full weeks.

  • Top 5 longest-lived Atlantic tropical cyclones
    1. San Cariaco Hurricane (1899) -- 27.75 days
    2. Ginger (1971) -- 27 days
    3. Inga (1969) -- 24.75 days
    4. Kyle (2002) -- 22 days
    5. Nadine (2012) -- 21.75 days

Meanwhile, Tropical Storm Oscar, which formed Wednesday, is gaining strength. Like Nadine, it is not expected to threaten the U.S., but unlike Nadine, it's not expected to stick around for long.
