It was slightly stronger, at 990 mbar instead of 992 mbar. If it became extratropical later on it would’ve peaked at 55 kt and 989 mbar.

I am neither a meteorology student nor a professional, I'm just 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.

The last TCR probably won't come until well into springtime at this rate.

I wonder how long it will take the NHC to writeup all these tropical cyclone reports for the Atlantic when all is said and done?

How long did it take for them to finish analysis for 2005?...
Do they usually try to finish these before the Spring WMO meeting or not necessarily?

At this rate, we should see Dolly’s TCR within the next two weeks (Cristobal will likely take longer due to its 9-day life span and multiple land impacts). I’m excited to see if the NHC bumps up Dolly’s peak intensity, which I think was around 50-55 kt.

Elida was upped to a stronger Cat2 than operationally assessed. It’s ICE is now 39.45 (90 kt and 971 mbar), up from 33.10 operational.

Interesting that they were able to finish Elida before some of those other weak storms, like Tropical Slop Boris.

I am in no way a professional. Take what I say with a grain of salt as I could be totally wrong. Please refer to the NHC for official information.

If I recall right, the Katrina was the last storm to have its report released, on 28 April 2006, although there were further updates with few of the storms' reports since then.

Tropical Storm Cristina has been released. Now that the season is finally winding down, these reports will be getting published at a quicker pace.

Douglas’s TCR is out for its EPac portion is out. Peaked just prior to entering the CPac (which likely won’t have its part released till like 2022 based on how agonizingly slow they go). No changes to intensity, remains 115 kt despite some talk of a higher intensity. IMO, seems fair.

Tropical Storm Lowell is out. Looks like they want to get out the EPAC storms first so they can be out of the way.

Nana has been released. No change in peak intensity. No downgrade here.
The 72kt FL and 62kt SFMR as well as Nana having a tiny core was noted as being enough data to support a hurricane.

This is a borderline case, but since it was such a small circulation, it would be prone to swings in intensity with any convective bursts. There was a significant burst just before landfall which likely spun it back up a bit just before landfall.

I know they mentioned the Carrie Bow Cay reading, but that should have got additional weight. That 53 kt was in the RMW. It does not say if that was 1-min, 2-min or 10-min sustained though. I did figure they'd find a reason to keep it a hurricane even if many of us disagree with it. IMO, if they had operationally gone 60 kt, they would have left it there.

IMO, if they had operationally gone 60 kt, they would have left it there.

Reviewing the data, I noticed that the 72-knot FL reading occurred ~13 n mi NNW of the centre at 02:12:30 UTC on 3 October. (The fix at the time reported 996 mb with 15-knot winds, which would translate to a central pressure of 994 mb. A subsequent fix at 04:37:00Z on the same date indicated 999 mb with 36-knot winds, which again translates to a central pressure of 994 mb. So the MSLP was relatively steady up until nearshore.) According to the TCR, the MSW of 53 knots at Carrie Bow Cay occurred at 05:42 UTC, while the minimum observed pressure of 998 mb occurred at 05:30 UTC. Based on both fixes and station data, the centre of Nana passed within ~8 n mi of Carrie Bow Cay, so the station was clearly inside the RMW at some point, while the eye of Nana passed south of the station as it headed WSW. I’m assuming that the MSW at Carrie Bow Cay was a 1-min observation at 10 m, which would fit the reconnaissance data rather well. Interestingly, SFMR registered a peak wind of 49 knots about ~17 n mi to the NNW of the centre at 04:32:00 UTC. Given the size of the near-average RMW, while noting the compact circulation (meaning high background pressures), and taking into account the trajectory of the centre, one deduces that while Carrie Bow Cay (~55 knots) was certainly inside the RMW at one point, it is possible that slightly stronger (~60 knots) winds occurred just north of the station. If this is the case, then the land data from Carrie Bow Cay indicate that SFMR was underestimating surface winds somewhat, since the station was reporting stronger winds closer to the centre than SFMR was reporting. Adding another five knots to account for this would actually support 65 knots in a very small area. So actually now the NHC’s classification begins to make sense, once one fully explores the data and applies reasoning.
