 On September 10 , a strong tropical wave emerged off the western coast of Africa . Passing south of Cape Verde , its interaction with a convectively @-@ coupled kelvin wave resulted in increased convection and the formation of an area of low pressure . After further organization , the wave acquired sufficient organization to be declared a tropical depression by 12 : 00 UTC on September 16 while located within the central Atlantic . Unfavorable upper @-@ level winds caused the appearance of the cyclone to become disheveled almost immediately after formation , and despite sporadic bursts of convection atop the storm 's center , the depression dissipated at 18 : 00 UTC on September 19 without ever attaining tropical storm intensity .
