NOAA: Early-season storms one indicator of active Atlantic hurricane season ahead

NOAA seem to believe that the signs are now there to indicate that the North Atlantic hurricane season is going to be a lot more lively that they thought back in June. So far we have had one short-lived North Atlantic hurricane, NOAA are now predicting between 5 and 9 this season. I’ve never seen them amend their forecast mid-season like this in the five years or so that I have been closely following the subject. I haven’t seen any tropical storm activity this year, although I could be wrong,  that has originated from around the Cape Verde Islands, which I would have thought would have been one of the prerequisites for hurricane development, but what the hell do I know.
