'''Tropical Depression Ten''' was a short-lived and weak [[tropical cyclone]] that was the tenth system of the record-breaking [[2005 Atlantic hurricane season]]. It formed on August 13 from a [[tropical wave]] that emerged from the west coast of Africa on August 8. As a result of strong [[wind shear]], the depression remained weak and did not strengthen beyond tropical depression status. It degenerated into a remnant low on August 14, but its remnants partially contributed to the formation of [[Hurricane Katrina]], after merging with a tropical wave on August 19. Thus, it is often referred to as "the precursor to Katrina". The cyclone had no effect on land and did not directly result in any fatalities or damage.

==Meteorological history==
{{storm path|10-L 2005 track.png|alt=Track map of tropical depression}}
On August 8, a [[tropical wave]] emerged from the west coast of Africa and entered the Atlantic Ocean. Tracking toward the west, the depression began to exhibit signs of [[Atmospheric convection|convective organization]] on August 11. The system continued to develop, and it is estimated that Tropical Depression Ten formed at 1200 UTC on August 13, located about {{convert|1600|mi|km}} east of [[Barbados]].<ref name="TCR">{{cite web|author=Beven, Jack L.|title=Tropical Cyclone Report: Tropical Depression Ten|url={{NHC TCR url|id=AL102005_Ten}}|publisher=National Oceanic and Atmospheric Administration|work=National Hurricane Center|date=2006-01-17|accessdate=2009-01-21|location=Miami, Florida|format=PDF}}</ref> Upon its designation, the depression consisted of a large area of thunderstorm activity, with curved [[tropical cyclone#Physical structure|banding features]] and expanding [[outflow (meteorology)|outflow]]. The environmental conditions were predicted to quickly become unfavorable, however.<ref>{{cite web|author=Avila, Lixion A.|title=Tropical Depression Ten Discussion Number 1|url=https://www.nhc.noaa.gov/archive/2005/dis/al102005.discus.001.shtml|publisher=National Oceanic and Atmospheric Administration|work=National Hurricane Center|date=2005-08-13|accessdate=2009-01-21|location=Miami, Florida}}</ref> The depression moved erratically and slowly towards the west, and [[wind shear]] inhibited any significant intensification. Late on August 13, it was "beginning to look like [[Hurricane Irene (2005)|Irene]]-junior as it undergoes southwesterly mid-level shear beneath the otherwise favorable upper-level outflow pattern".<ref name="disc2"/> The wind shear was expected to relent within 48 hours, prompting some forecast models to suggest the depression would eventually attain hurricane status.<ref name="disc2">{{cite web|author=Stewart, Stacy R.|title=Tropical Depression Ten Discussion Number 2|url=https://www.nhc.noaa.gov/archive/2005/dis/al102005.discus.002.shtml|publisher=National Oceanic and Atmospheric Administration|work=National Hurricane Center|date=2005-08-13|accessdate=2008-01-21|location=Miami, Florida}}</ref>

By early August 14, the shear had substantially disrupted the storm, leaving the low-level [[atmospheric circulation|center of circulation]] exposed from the area of convection, which was also deteriorating. After meandering, the storm began to move westward. Forecasters expected it to resume a northwestward track as [[high pressure area|high pressure]] to the south of [[Bermuda]] was forecast to weaken and another high was predicted to form southwest of the [[Azores]].<ref>{{cite web|author=Knabb, Richard D.|title=Tropical Depression Ten Discussion Number 3|url=https://www.nhc.noaa.gov/archive/2005/dis/al102005.discus.003.shtml|publisher=National Oceanic and Atmospheric Administration|work=National Hurricane Center|date=2005-08-14|accessdate=2009-01-21|location=Miami, Florida}}</ref> By 1800 UTC on August 14, the strong shear had further weakened the storm, and it no longer met the criteria for a tropical cyclone. It degenerated into a remnant low, and the National Hurricane Center issued their final advisory on the cyclone. Moving westward, it occasionally produced bursts of convective activity, before merging with another tropical wave on August 19.<ref name="TCR"/>

Tropical Depression Twelve formed over the southeastern [[Bahamas]] at 2100 UTC on August 23, partially from the remnants of Tropical Depression Ten.<ref>{{cite book|page=61|url=https://books.google.com/?id=-a8DRl1HuwoC&q=%22tropical+depression+ten%22+2005&dq=%22tropical+depression+ten%22+2005|author=United States Senate|title=Hurricane Katrina: a nation still unprepared|publisher=U.S. Government Printing Office|year=2006|isbn=0-16-076749-0|accessdate=2014-11-05}}</ref><ref>{{cite web|author=Michael P.

As a result, the criteria for keeping the same name and identity were not met. Tropical Depression Twelve later became [[Hurricane Katrina]].<ref name="Ktcr">{{cite report|author=Knabb, Richard D.|author2=Rhome, Jamie R.|author3=Brown, Daniel P.|title=Tropical Cyclone Report: Hurricane Katrina|url={{NHC TCR url|id=AL122005_Katrina}}|publisher=National Oceanic and Atmospheric Administration|work=National Hurricane Center|date=2005-12-20|accessdate=2009-01-21|location=Miami, Florida|format=PDF}}</ref>

==Impact==
Because Tropical Depression Ten never approached land as a [[tropical cyclone]], no [[tropical cyclone watches and warnings]] were issued. No effects, damages, or fatalities were reported, and no ships reported tropical storm-force winds in association with the depression. The system did not attain tropical storm status and was not given a name by the [[National Hurricane Center]].<ref name="TCR"/> The storm partially contributed to the formation of Hurricane Katrina, which became a [[List of Category 5 Atlantic hurricanes|Category 5]] hurricane on the [[Saffir–Simpson Hurricane Scale]] and made landfall in [[Louisiana]] and Mississippi, causing catastrophic damage, becoming one of the five deadliest hurricanes in the history of the United States.<ref name="Ktcr"/>
