Yes it does hinder development of future systems passing over, but also depends on the intensity of the system. Water is usually only heated to a certain depth- 30 meter's is usually the average for warm water 27 C and up, as you go down in temperature a more consistent temperature can be maintained. When weak disturbances pass over not much water is turned /upwelled, such as near Cape Verde; but once you get into major hurricanes region's (in the central atlantic and Gulf) significant upwelling can occur to such a point that it can hinder development of future systems. Hope that helps!.
