Subtropical Depression 22 was a subtropical depression in the 2005 Atlantic hurricane season, forming from a non-tropical low 450 miles southeast of Bermuda on October 8. After forming, the depression encountered unfavorable conditions, which caused a discontinuation of advisories the same night on the system at 11:00 PM EDT. The remnants of the system continued to be monitored by the NHC, with the extratropical system pulliing up tropical moisture (while strengthening into tropical storm intensity) into the northeastern United States. This system, along with the remnants Tropical Storm Tammy, contributed to severe flooding in the northeastern United States in the early to middle part of October, killing 10 people, and causing significant damage.

The system originated out of a non-tropical low, becoming a subtropical depression when that low was centered 450 miles southeast of Bermuda on October 8. After becoming a subtropical depression, the system moved northwest, and eventually north, and then moved very erratically in different directions before it reached the northeastern coast of the United States. The system dissipated at 11:00 PM EDT later on October 8, because it encountered unfavorable conditions, thus advisories from the National Hurricane Center were discontinued after that. The remnants of the system continued to be monitored. The system, as an extratropical system, continued to pull up tropical moisture into the northeastern United States (also reaching tropical storm strength later on) and it, combined with the remnants of Tropical Storm Tammy, contributed to severe flooding in the northeastern United States.
Naming and Records
If this system would've been named Subtropical Storm Vince (because it did indeed reach tropical storm strength shortly before making its way to the northeastern coast of the United States), it would've been the earliest in an Atlantic hurricane season that the 20th tropical or subtropical storm formed in the Atlantic basin.
Because this system was unnamed, it was not retired by the World Meteorological Organization in the Spring of 2006. Even if it would've been named, it would not have been retired, due to its minimal effects on the United States.
