E pronto, acabou finalmente. Desde o 1º até ao 88º aviso, passaram 23 dias. Como sistema tropical foram 21.75 dias segundo o NHC, o 5ª ciclone com vida mais longa dos registos no Atlântico.

BYE BYE NADINE. AFTER TRAVELING FOR OVER THREE WEEKS ACROSS THE
EASTERN ATLANTIC...AFFECTING THE AZORES TWICE...AND AFTER 88 NHC
ADVISORIES...NADINE HAS FINALLY DISSIPATED. SATELLITE IMAGES AND
ASCAT DATA INDICATE THAT BY 1200 UTC THIS MORNING...NADINE NO
LONGER HAD A CLOSED CIRCULATION AND HAD BECOME ASSOCIATED WITH A
COLD FRONT. 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-LASTING
TROPICAL CYCLONE ON RECORD IN THE BASIN...AT 21.75 DAYS.

GLOBAL MODELS KEEP A VORTICITY MAXIMUM...ASSOCIATED WITH THE
REMNANTS OF NADINE...EMBEDDED WITHIN A LARGE EXTRATROPICAL CYCLONE.
THIS FEATURE IS EXPECTED TO MOVE RAPIDLY NORTHWARD AND DISSIPATE IN
A DAY OR TWO.

NHC has issued its last advisory on long-lived Nadine. After a long and strange trek over the Atlantic Ocean, Nadine no longer has a closed circulation and has become associated with a cold front.
The Tropical Storm Warning for the Azores has been discontinued.
Pending a post-storm analysis, Nadine is tied for 2nd place with 1971's Ginger as the longest time spent of at least tropical storm intensity in the Atlantic basin at 21.25 days. First place is held by the "San Ciriaco Hurricane" of 1899 at 28 days.
Nadine is also in 5th place as the longest time spent as a tropical cyclone (tropical depression, tropical storm, hurricane) in the Atlantic basin at 21.75 days, behind 2002's Kyle, 1969's Inga, 1971's Ginger, and the "San Ciriaco Hurricane" of 1899.

NHC emitiu seu último aviso sobre Nadine Long-lived. Após uma caminhada longa e estranha sobre o Oceano Atlântico, Nadine já não tem uma circulação fechada e tornou-se associado uma frente fria.
Aviso de tempestade Tropical para os Açores foi descontinuado.
Pendentes uma análises pós-tempestade, Nadine está empatada em 2º lugar com Ginger em 1971 como o maior tempo gasto pelo menos intensidade de tempestade tropical na bacia do atlântica em dias 21.25. Primeiro lugar é realizado pelo "San Ciriaco furacão" de 1899 em 28 dias.
Nadine é também em 5º lugar como o maior tempo gasto como um ciclone tropical (depressão tropical, tempestade tropical, furacão) na bacia do atlântica em dias 21.75, atrás do 2002 Kyle, do 1969 Inga, gengibre do 1971 e "San Ciriaco furacão" de 1899.

Um sistema deveras interessante e muito bom para estudos aprofundados da dinâmica da atmosfera.
Acredito que, nos próximos anos, muitos profissionais e estudantes na área da meteorologia vão centrar as suas atenções neste sistema tropical.
Durabilidade, percurso, temperatura da água do mar no seu trajecto, anticiclones\depressões que a afectaram, etc., vão permitir conhecer ainda melhor esta companheira dos Açorianos:D

You only die twice: Atlantic's 2nd longest TS of all-time is dead

The interminable, long-lived, pesky, persistent, perpetual, never-say-day, tenacious, non-stop, I'm-not-dead-yet, Energizer-bunny-like Methuselah of Atlantic tropical cyclones, Tropical Storm Nadine, finally met its permanent doom this morning, but not before bringing tropical storm conditions to the northwest Azores Islands. Sustained winds of 43 mph, gusting to 54 mph, were recorded at Lajes at 8 am local time, as Nadine was completing its transition to an extratropical storm. Today is Nadine's 2nd death; the storm also became extratropical for just over a day on September 22. Nadine logged 21.75 days as a tropical or subtropical cyclone as of 2 am today, making it the fifth longest-lived Atlantic tropical cyclone of all-time (tropical cyclones include tropical depressions, tropical storms, and hurricanes, but not extratropical storms.) Nadine's 21.25 days as a tropical or subtropical storm make it tied with Hurricane Ginger of 1971 as the Atlantic's second longest tropical storm on record. Only the San Ciriaco Hurricane of 1899 (28 days) was longer-lived. About one-quarter of this year's total Accumulated Cyclone Energy (ACE) in the Atlantic basin so far is due to Nadine. According to the official HURDAT Atlantic database, which goes back to 1851, here are the four previous Atlantic tropical cyclones have lasted longer than Nadine (thanks go to Brian McNoldy for these stats):

1) San Ciriaco Hurricane of 1899: 28 days
2) Ginger, 1971: 27.25 days
3) Inga, 1969: 24.75 days
4) Kyle, 2002: 22 days
5) Nadine, 2012: 21.75 days

The National Hurricane Center issued 88 advisories on Nadine, and lucky NHC hurricane specialist Lixion Avila got to write the final epitaph in today's 11 am EDT advisory: "Bye bye Nadine...what a long strange trip its been." See you again in 2018, Nadine.
