'''Tropical Storm Debby''' was the fifth [[tropical cyclone|tropical storm]] of the [[2006 Atlantic hurricane season]]. Debby formed just off the coast of [[Africa]] on [[August 21]] from a [[tropical wave]]. After passing near the [[Cape Verde]] islands, Debby moved generally northwestward for much of its life, reaching a peak intensity of 50 mph (85 km/h). Strong [[wind shear]] weakened the storm, and Debby dissipated on [[August 27]] over the northern [[Atlantic Ocean]].

Early in its life, Debby was forecasted to pass through the southern [[Cape Verde]] [[island]]s as a tropical storm, possibly causing life-threatening [[flood]]ing. Most computer models consistently predicted Debby to move to the northwest throughout its lifetime, though intensity was more of a problem for forecasters. The [[National Hurricane Center]] continually predicted Debby to strengthen into hurricane status, though strong vertical shear eventually prevented the storm from becoming a hurricane.

==Storm history==
{{storm path|Debby 2006 track.png}}
A strong [[tropical wave]] moved off the coast of [[Africa]] late on [[August 20]], and almost convective banding and a broad circulation.<ref name="tcr">{{Cite web|author=James L.

Water temperatures remained warm enough for development, while upper level shear was minimal as the depression moved west-northwestward because of a ridge of high pressure to its north.<ref name="td1disc">{{cite web|author=Franklin|year=2006|title=Tropical Depression One Discussion|publisher=NHC|accessdate=2006-09-05|url=ftp://ftp.met.fsu.edu/pub/weather/tropical/Outlook-A/2006082115.ABNT20}}</ref> Original predictions by the [[National Hurricane Center]] also forecasted a turn to the northwest based computer model predictions, as quoted by forecaster James Franklin, "The models have also been excellently wrong thus far".<ref name="tddisc1">{{cite web|author=Franklin|year=2006|title=Tropical Depression Four Discussion Two|publisher=NHC|accessdate=2006-09-05|url=http://www.nhc.noaa.gov/archive/2006/dis/al042006.discus.002.shtml?}}</ref>

In spite of a decrease in convection shortly after forming, the large depression remained well organized, with a 575 mile wide wind field.<ref name="tddisc1"/> On [[August 22]], as it passed 140 miles (225&nbsp;km) miles to south of the [[Cape Verde]] islands, deep convection developed over the center of circulation,<ref name="td4disc3">{{cite web|author=Brown|year=2006|title=Tropical Depression Four Discussion Three|publisher=NHC|accessdate=2006-09-05|url=http://www.nhc.noaa.gov/archive/2006/dis/al042006.discus.003.shtml?}}</ref> and early on [[August 23]] the depression strengthened into Tropical Storm Debby about 300 miles southwest of Cape Verde.<ref name="tcr"/> Banding features continued to organize as the system slowly strengthened,<ref name="debbydisc7">{{cite web|author=Brown|year=2006|title=Tropical Storm Debby Discussion Seven|publisher=NHC|accessdate=2006-09-05|url=http://www.nhc.noaa.gov/archive/2006/dis/al042006.discus.007.shtml?}}</ref> and on [[August 23]] Debby reached its peak intensity of 50&nbsp;mph over the open waters of the [[Atlantic Ocean]].

Shortly after reaching its peak intensity, Debby encountered an area of dry air, and as a result weakened.

The low turned to the north and north-northeast ahead of an approaching [[trough (meteorology)|trough]], and on [[August 28]] the low dissipated.<ref name="tcr"/>

Though the storm was forecasted to remain far away from the [[Gulf of Mexico]], investors tracking the storm caused the price of [[crude oil]] to rise 60 cents a barrel due to the possible impact to oil installations.<ref name="oil">{{cite web|author=[[Agence France-Presse]]|year=2006|title=Oil prices up on new BP cut|accessdate=2006-09-05|url=http://www.news.com.au/dailytelegraph/story/0,22049,20246735-14334,00.html}}</ref>
