Hurricane season=2005 Atlantic hurricane season Tropical Storm Zeta was a late-developing
tropical storm over the centralAtlantic which formed after the2005 Atlantic hurricane season had officially ended, and continued into January. It extended the record number of storms in a season to twenty-eight.Zeta developed late on
December 29 and headed to the west. Throughout the storm's lifetime, theNational Hurricane Center continually predicted it would weaken rapidly. Like the previous tropical cyclone Hurricane Epsilon, Zeta defied these predictions. The storm reached its peak strength onJanuary 2 ,2006 before finally dissipating onJanuary 6 . As Zeta never approached land there was no impact from the storm.Meteorological history
Late on
December 29 ,2005 , a tropical depression developed in the east-central Atlantic from a frontal trough and became a tropical storm early the next day. As this was more than four weeks after the official end of the season, theNational Hurricane Center didn't operationally notice the system until after it had already become a tropical storm.cite web|author=National Hurricane Center|title=Tropical Cyclone Report: Tropical Storm Zeta|publisher=NOAA|accessdate=May 1|accessyear=2006|format=PDF|url=http://www.nhc.noaa.gov/pdf/TCR-AL312005_Zeta.pdf] Initially the storm headed to the northwest but stalled late onDecember 31 before heading westwards, gradually strengthening to winds of 60 mph (95 km/h) as it did so. As with the previous storm, Hurricane Epsilon, theNational Hurricane Center continuously forecast that Zeta would weaken in response to high level shear but Zeta held onto its strength, like Epsilon had done.cite web|author=National Hurricane Center|title=Discussion for Tropical Storm Zeta, 10 p.m. EST, January 1 2006|publisher=NOAA|accessdate=May 1|accessyear=2006|url=http://www.nhc.noaa.gov/archive/2005/dis/al302005.discus.011.shtml]Tropical Storm Zeta weakened slightly on
January 2 , before intensifying further to its peak strength with 65 mph (100 km/h) winds. One of the models suggested that Zeta could strengthen further and become a hurricane but this did not occur.cite web|author=National Hurricane Center|title=Discussion for Tropical Storm Zeta, 4 a.m. EST, January 3 2006|publisher=NOAA|accessdate=May 1|accessyear=2006|url=http://www.nhc.noaa.gov/archive/2005/dis/al302005.discus.016.shtml] Tropical Storm Zeta continued to defy forecasts of weakening and onJanuary 4 increasing frustration led NHC forecaster, Dr.Lixion Avila to say that he had "run out [of] things to say".cite web|author=National Hurricane Center|title=Discussion for Tropical Storm Zeta, 10 a.m. EST, January 4 2006|publisher=NOAA|accessdate=May 1|accessyear=2006|url=http://www.nhc.noaa.gov/archive/2005/dis/al302005.discus.021.shtml]The effects of wind shear finally took their toll late on
January 4 , and Zeta's convection began to die down. This led to Tropical Storm Zeta weakening to a minimal tropical storm. The NHC continued to overestimate how quickly Zeta would dissipate and early onJanuary 5 they operationally downgraded Zeta to a depression, which was later confirmed to have been an error.cite web|author=National Hurricane Center|title=Discussion for Tropical Storm Zeta, 4 a.m. EST, January 5 2006|publisher=NOAA|accessdate=May 1|accessyear=2006|url=http://www.nhc.noaa.gov/archive/2005/dis/al302005.discus.024.shtml] Zeta continued to move west-northwestward, barely holding on to tropical storm status before becoming disorganized again. Zeta weakened into a tropical depression onJanuary 6 and dissipated into a remnant later that day, finally ending the 2005 season. The remnant low retained its identity for a further day before it dissipated 660 miles (1060 km) southeast ofBermuda .Impact and records
Several of the crews that were taking part in the 2005
Atlantic Rowing Race were affected with heavy seas and strong adverse winds from Tropical Storm Zeta.cite web|author=Woodvale Events Ltd|title=Atlantic Rowing Race 2005 Press Release: Tropical Storm Zeta|accessdate=May 1|accessyear=2006|url=http://www.atlanticrowingrace.co.uk/news_releases/newsdetail.php?id=32] The ship "Liberty Star" made several reports of strong winds from Tropical Storm Zeta, including one of 40 mph (65 km/h) winds early onDecember 31 , when the ship was about 45 miles (75 km) north of the center of the storm.Tropical Storm Zeta never threatened land so no coastal watches or warnings were issued. There was no reported damage or fatalities from Zeta.
When Tropical Storm Zeta formed at 0600
UTC onDecember 31 , it became the second latest-forming tropical cyclone ever recorded in the Atlantic, forming about six hours earlier than Hurricane Alice did in 1954. Zeta is only the second Atlantic tropical cyclone on record to have existed in two calendar years (after Alice). However, lasting seven full days (six of them in 2006), Zeta is the longest-lasting tropical storm on record for the month of January. Tropical Storm Zeta also extended the record number of storms to form in the 2005 season to twenty-eight, seven more than the previous record held by the 1933 season. It was the only Atlantic storm to have a name beginning with the letter "Z", because the lists of names for Atlantic storms stop at "W".See also
