:Tropical Depression Five (2010)

{{storm path|5-L 2010 track.png}}

The origins of the depression were from a dissipating cold front that extended from the northeast Gulf of Mexico across Florida on August 7, connected to a weak non-tropical low-pressure area located several hundred miles east-southeast of Jacksonville, Florida. The system had disorganized convection– thunderstorms– and moved generally southwestward after drifting against the Gulf Stream.{{cite web|author=Michael Brennan|date=2010-11-04|publisher=National Hurricane Center|title=Tropical Depression Five Tropical Cyclone Report|access-date=January 1, 2012|url={{NHC TCR url|id=AL052010_Five}}|format=PDF}}{{cite web|author=Mike Formosa|date=August 8, 2010|title=Tropical Weather Discussion|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/text/TWDAT/2010/TWDAT.201008082357.txt}}{{cite web|author=Eric Blake|author2=Daniel Brown|date=August 8, 2010|title=Tropical Weather Outlook|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/text/TWOAT/2010/TWOAT.201008081735.txt}} Conditions were initially unfavorable for development, due to strong upper-level wind shear and land interaction.{{cite web|author=Richard Pasch|author2=Todd Kimberlain|date=August 8, 2010|title=Tropical Weather Outlook|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/text/TWOAT/2010/TWOAT.201008082332.txt}} By late August 9, the low reached the southeastern Gulf of Mexico, and the National Hurricane Center (NHC) noted a medium chance for tropical or subtropical development, due to an anticipated decrease in wind shear.{{cite web|author=Richard Pasch|author2=Todd Kimberlain|date=August 9, 2010|title=Tropical Weather Outlook|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/text/TWOAT/2010/TWOAT.201008092333.txt}} The convection gradually increased and became better organized,{{cite web|author=Stacy Stewart|date=August 10, 2010|title=Tropical Weather Outlook|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/text/TWOAT/2010/TWOAT.201008100534.txt}} and a hurricane hunters flight late on August 10 confirmed the development of Tropical Depression Five about {{convert|120|mi|km}} west of Fort Myers, Florida.{{cite web|author=Richard Pasch|author2=Todd Kimberlain|date=August 10, 2010|title=Tropical Depression Five Special Discussion One|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/2010/al05/al052010.discus.001.shtml?}}

Upon being classified as a tropical cyclone, the tropical depression had a broad circulation and organized deep convection. It was located over very warm water temperatures, although the upper-level environment was not conducive for significant intensification. Easterly wind shear was forecast, but the NHC anticipated the depression strengthening to {{convert|45|mph|km/h|abbr=on|round=5}} before making landfall in Louisiana. Under the influence of a mid-level ridge to its north, the depression was forecast to track generally northwestward. Early on August 11, the convection diminished significantly due to the entrainment of dry air and vertical wind shear from a nearby upper-level low. The circulation became difficult to locate; however, conditions favored the redevelopment of the thunderstorm activity. One tropical cyclone prediction model forecast significant intensification to a minimum pressure of 968 mbar, and other models forecast the depression would reach hurricane status upon making landfall.{{cite web|author=Stacy Stewart|date=August 10, 2010|title=Tropical Depression Five Discussion Three|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/2010/al05/al052010.discus.003.shtml?}} As it continued to the northwest, the circulation remained broad and disorganized, and convection remained minimal. Late on August 11, a hurricane hunters flight reported that the depression was no longer a tropical cyclone,{{cite web|author=Eric Brown|date=August 11, 2010|title=Tropical Depression Five Discussion Five|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/2010/al05/al052010.discus.005.shtml?}} and in post-analysis, the NHC determined that the depression was only a tropical cyclone for 12 hours. Redevelopment was not anticipated.{{cite web|author=Richard Pasch|author2=Todd Kimberlain|date=August 11, 2010|title=Tropical Weather Outlook|publisher=National Hurricane Center|access-date=August 15, 2010|url=http://www.nhc.noaa.gov/archive/text/TWOAT/2010/TWOAT.201008112331.txt}}

Prior to becoming a tropical cyclone, the system dropped locally heavy rainfall in portions of southern Florida. Palm Beach International Airport recorded {{convert|2.25|in|cm}} on August 8, a record for the date. The system spawned a weak tornado near Boca Raton, which downed a few trees and damaged shingles from one house.{{cite news|author=Sonja Isger and Eliot Kleinberg |date=August 9, 2010 |title=Tropical system dropped rain in Palm Beach County before moving into Gulf |agency=Palm Beach Post |access-date=August 15, 2010 |url=http://www.palmbeachpost.com/weather-news/tropical-system-dropped-rain-in-palm-beach-county-849030.html |url-status=dead |archive-url=https://web.archive.org/web/20100908134455/http://www.palmbeachpost.com/weather-news/tropical-system-dropped-rain-in-palm-beach-county-849030.html |archive-date=September 8, 2010 }} In Sarasota, high tides from the system affected 200 sea turtle nests, of which 20 had to be transported to a safer location.{{cite web|publisher=Bradenton Herald|date=August 14, 2010|title=T.D. 5 sent high water over sea turtle nests|access-date=August 16, 2010|url=http://www.bradenton.com/2010/08/14/2505410/td-5-sent-high-water-over-sea.html|url-status=dead|archive-url=https://archive.today/20120728002400/http://www.bradenton.com/2010/08/14/2505410/td-5-sent-high-water-over-sea.html|archive-date=July 28, 2012}} Once in the Gulf of Mexico, the developing system threatened the area affected by the Deepwater Horizon oil spill; this prompted BP to stop operations temporarily in constructing a relief well.{{cite news|author1=Jim Polson|author2=Brian K.
