There is only one tropical storm located in the Atlantic, T.S. Oscar, which is the 15th named storm this season. Oscar will pose no threat to the U.S. It is looking more and more likely that we have seen all of the tropical activity for the season.
T. S. Nadine departed as the #5 longest-lived atlantic tropical cyclone of all time. It is also tied with Ginger of 1971 as the 2nd longest lasting atlantic tropical storm on record at 21.25 days.
From time to time, I will show the Accumulated Cyclone Energy Index (ACE), which is a useful way to show how active the season has been. The current ACE is about 20% above normal for this time of year. However, the unusually-long-lasting Nadine was responsible for as much as 25% of this total. Without this anomaly (duration of Nadine), the season (as measured by theACE) would be below normal. Also, note the decrease in ACE over the past 2 seasons.
