Going with 4 storms, including 2 hurricanes (both majors).

Went with 6 or more, 2022 might keep trolling us with a hyperactive October after what we've seen this month

Re: How many named storms will form in October?
Yeah my vote of zero was prematurely bearish lol. I now think we’ll see between 2-4 storms.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Re: How many named storms will form in October?
I am going to be ballsy and go with 6 storms, including 4 hurricanes and 2 major hurricanes with a season-to-date total of 16 storms, 8 hurricanes, and 4 major hurricanes (yes I think 99L will develop). I think November will divide October in half and feature 3 storms, 2 hurricanes, and 1 major (sorta similar to 2020 but the major here would be 115 mph instead of two 155s). Then I think one more named storm in December and the season ends with 20 named storms, 10 hurricanes, and 5 major hurricanes tying it with 1933 as the fourth-busiest season and being a historically backloaded season with 5 storms forming before peak and 15 after (75%). Let's see how my prediction pans out. Edit* apparently models are still showing MDR development for the first week of October provide a further case that we're experiencing a delayed season.

Observations
Over the past 27 years, it seems the Atlantic liked to switch from frontloaded to backloaded phases, stay normal for a bit, then go to switching. The 3-year period 1995-1997 were back-to-back frontloaded or at least slightly frontloaded (in '95's case) seasons. 1997 was EXTREMELY frontloaded with 92% of its total storms forming before September 10. Then we get a 5-year streak of backloaded seasons 1998-2002 aside from 1999 which was normal (2000 and 2002 were both VERY backloaded). Then we get a 10-year streak of frontloaded seasons from 2003-2012 aside from 2005 and 2010 which were only slightly frontloaded (though 2010 was backloaded hurricane-wise) and 2006 which was backloaded (though it was very frontloaded named-storm-wise). Then comes the string of seasons (6 years) with even distribution from 2013-2018 aside from 2014 which was backloaded (though it was even for both named storms and hurricanes; it was the majors that made it backloaded, 2016 was only slightly backloaded despite late season majors). Then we return to primary backloaded seasons from 2019 to now which the exception of 2021 which was unusually frontloaded and had an anomalously inactive October. This year looks to contine the trend of backloaded seasons! Truly fascinating stuff.
1995-1997: Frontloaded Phase
1998-2002: Backloaded Phase (5 years)
2003-2012: Frontloaded Phase (10 years)
2013-2018: Normal Phase (6 years)
2019-Present: Backloaded Phase (minus 2021 anomaly)

Re: How many named storms will form in October?
awesome analysis Ryxn!! This was really neat to read and yep you may be onto something.
Something was telling me this season was going to be backloaded as heck, almost like 2019-2020.
2022 may have us kinda fooled so far, so perhaps we do get to 19-20 NS afterall, at least this is back on the table especially if 99L gets the J name soon.
October will likely be above average, especially given the model runs still showing MDR activity. It's as if this season is running a month behind, so perhaps October will keep acting as September and November as October. Imagine if instead of 2 155mph systems in Nov, we get 1 175+ mph beast instead! It would be even crazier if it was the last Nov system in Late November, this year would be that weird to have stuff like this imo. Gonna be interesting times ahead, after Ian.

I appreciate the support! Aha yeah it took a few hours to lay out these stats. I find it fascinating.

Can't decide between 4 or 5 because I'm thinking that the Momentum of September will carry into October.

Re: How many named storms will form in October?
The winner was 3: Julia, Karl, and Lisa (barely). While it’s possible Invest 94L gets a post-season upgrade, it was probably nothing more than a brief TD and wouldn’t change the winning number.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

I think more likely is that Martin's genesis is moved forward 12+ hours
