extratropical low-pressure area on November 26. After losing frontal characteristics, the system transitioned into Subtropical Storm Otto at 12:00 UTC on November 29, while located about east-southeast of Bermuda. Initially, the storm moved northwestward due to a weakness in a subtropical ridge. Late on November 29, Otto attained its maximum sustained wind speed of . Deep convection formed near the center and the storm began transitioning to a warm core system. The system was re-classified as Tropical Storm Otto at 12:00 UTC on November 30, although it is possible that Otto transitioned to a fully tropical cyclone one day earlier, on November 29. Although sea temperatures were relatively cold, Otto did not quickly weaken, because of low wind shear. On December 1, the storm curved southeastward and completed a cyclonic loop later that day. After wind shear began increasing, Otto started weakening and was downgraded to a tropical depression at 12:00 UTC on December 2. At that, Otto reached its minimum barometric pressure of . Early on December 3, the storm degenerated into a remnant low while located about southeast of Bermuda. Otto was the first tropical cyclone to form in the month of November since Olga of 2001. Season effects The following table lists all of the storms that formed in the 2004 Atlantic hurricane season. It includes their duration, names, intensities, areas affected, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2004 USD. Storm names The following names were used for named storms that formed in the North Atlantic in 2004. This is the same list used for the 1998 season except for Gaston and Matthew, which replaced Georges and Mitch. The names not retired from this list were used again in 2010. Storms were named Gaston, Matthew, and Otto for the first time in 2004. Retirement On April 5, 2005, The World Meteorological Organization retired four names – Charley, Frances, Ivan, and Jeanne due to extreme damages and death toll and will not be used again for an Atlantic hurricane. They were replaced in the 2010 season by Colin, Fiona, Igor, and Julia. The 2004 season is tied with the 1955, 1995, and
