As a point of information, there have been no North Atlantic hurricanes in August to date. That's quite unusual, but can be explained via meteorological vicissitudes rather than global warming issues.

Tropical storms/ hurricanes/ tropical cyclones have very different origins from Atlantic depressions. The latter are always linked to the jet stream, unlike the former, which are not. A very active zonal flow of depressions is completely unconnected to the genesis of tropical storms.
