So in last 25 years, the earliest D- storm was July 5 2005 (DENNIS), the latest formed D-storm in the same period was Sep 27 1983 (DEAN).

And in last 25 years, 14 D-storms have formed later than August 20.

Pretty interesting statistics.

Great summary! That's probably one of the reasons why the "peak" of the season September 10.

Yes, thanks for the info....it seems pretty normal for the D storm to wait until after mid august to form. Good work.

Yes this season's named storm totals is currently normal. But there is just one problem here. For now at least. If you take a look at the preseason forecasts, from this forum's members, most were forecasting anything but normal.

A good deal of them were forecasting 50-70 % above normal activty. Some even higher . So trying to save grace by bringing up average is quite misleading. Is the season over? Of course not and some recent spaace weather conditons during the past few days, (some was the strongest this year) can only help the tropics in my opinion.

I think senorpepr has a more comprehensive post over in the analysis forum.

Whem the D storm is after Sept 1 most seasons will then have less then 10storms.

[AussieMark]

1961 had a August will null activity

what happened next 10 storms formed in the Sep-Nov period
with 8 hurricanes
and 6 majors

also look at 1998
between AUgust 20 and September 24 a total of 10 storms formed
it was actually 10/7/2 in that month
the first hurricane never came till August 22

look at 2001
between August 17 and September 22 a total of 6 storms formed
it was 6/4/2
and October - November was
7/5/2
the first hurricane never came till September 9
