I notice NHC says the remnants of Gordon are possibly going to re-develop at some point...does anyone know if those would be named Gordon again, or would that be a whole new storm?

I expect the number of tropical storms in the next month to be on average near the climatological mean. Using a couple different climatological estimates, I get the 11-15 bin as the most likely, with 0-10 as the second most likely. This contrasts with the ACE market where I still expect above normal ACE with albeit fewer, more powerful storms.

Edit: Ran the same analysis again with Francine, still 11-15 bin as likely. With ACE, now I expect normal ACE (or near normal) ...

September 9 is when we have on average our 8th storm. Francine makes 7. This puts us a week behind the seasonal average of 14, right in the middle of the 11-15 bin.

NHC is also forceasting a TC in the next week at 70% chance, so this matches as well.

Standard linear regression: n_storms = 0.2857 year - 557.8

R^2=0.221 - so the year only captures a bit of the variance

Year-based estimate: 20.4568 storms

Data is at the bottom.

I also did a simulation with a linear model and increasing variance and then multiplied the posterior storms by 1+HalfNormal(0.1). (I'll post a notebook link when I have time.) It identified some of the items as under-estimated. But when I bet, they went haywire. So, I've provided some more liquidity. But I reached my limit. Someone else will need to correct the huge overestimate for 36+. It was fun, but a lot of time for 191 Manna (expected).

@EricMoyer You are counting (unnamed named storms) and tropical depressions in your count ...

Edit: Here is the count I get from IBtracks NA:

{1966: 15, 1967: 13, 1968: 9, 1969: 18, 1970: 14, 1971: 13, 1972: 7, 1973: 8, 1974: 11, 1975: 9, 1976: 10, 1977: 6, 1978: 12, 1979: 9, 1980: 11, 1981: 12, 1982: 6, 1983: 4, 1984: 13, 1985: 11, 1986: 6, 1987: 7, 1988: 12, 1989: 11, 1990: 14, 1991: 8, 1992: 7, 1993: 8, 1994: 7, 1995: 19, 1996: 13, 1997: 8, 1998: 14, 1999: 12, 2000: 15, 2001: 15, 2002: 12, 2003: 16, 2004: 15, 2005: 28, 2006: 10, 2007: 15, 2008: 16, 2009: 9, 2010: 19, 2011: 19, 2012: 19, 2013: 14, 2014: 8, 2015: 11, 2016: 15, 2017: 17, 2018: 15, 2019: 18, 2020: 30, 2021: 21, 2022: 14, 2023: 19}

Edit: deleted. Nevermind, this is satisfied by the resolution criteria.

@ScottSupak Just wondering, what makes you expect that this hurricane season will be so disastrous?

@TimothyJohnson5c16 Record high ssts and an emerging la Nina

NOAA predicts 17-25 named storms:
