On a radar loop, looks like Josh’s location got a dry slot in the south eyewall (weak side) rather than the true eye. Though 110kt was based on an extrapolation of trends from the last flight so could see a bump down to 105.

Likely we'll see a downgrade to 105 kt for Grace's peak wit h a 100 kt landfall after figuring in the fact he was likely in a dry slot instead of the true eye, as Ubuntwo stated

Kate: Maybe a primary peak as a 35 kt TS added based on ASCAT data which showed 1 35 kt barb about 12 hours after the designation


There were 2-3 40kt barbs at the time they designated.

Danny's report got a small update BTW. It's just an adjustment to the storm surge levels.

actually, that was at naming. There was an earlier peak, about 12 hours after it was designated as a TD, with 1 35 kt barb. It was between advisories however, and by the next advisory, the presentation had degraded.

Pressure dropped a couple mb to 993 and it looks like the 50kt peak has been extended.

ETT was also put 6 hours later than operationally, and we had a fairly significant net ACE gain for such a short-lived storm. I expect the next TCR will likely be Kate, or possibly Claudette.

Changes I would make:
1. Upgrade Invest 92L (Unnamed subtropical storm)
2. Upgrade Invest 94L (Unnamed subtropical storm)

Though I agree that 92L was likely a subtropical storm for a short while, it may not have been long enough to breach the 6 hour rule. 94L still has a good chance to be named. If it forms though, its duration will likely be extended rather significantly in its TCR.

So how much ACE it Julian gain after that report? It probably more than doubled its tiny output.

You would be correct. Julian's ACE jumped from 0.5 to 1.1 with the TCR. The updated data is not in HURDAT yet, so if anyone wants to double check be my guest.

Tropical Storm Odette is up.

Time while a TC was knocked down to 12 hours, a decision which seems very reasonable given the multiple LLCs it had while it was supposedly a TC in real-time.

I still strongly disagree with their reanalysis given ASCAT clearly showed an elongated trough the duration of its existence. Not a TC and should have been removed from the database IMO.

That report probably only took a hour to complete considering this storm's very short existence.

Cindy in 2017, quite a few storms in the Gulf actually. Those are generally large vorts and not closed in their own right, despite their appearance on satellite.

This is blatantly false as there were no full passes on the 17th, and the partial pass that led to upgrade, along with cloud motion, indicated a tighter circulation under the convection.

Even on the 18th, before it started elongating later in the afternoon, there's a clear broad but circular location--something common with disorganized subtropical systems.

That said do not understand the reasoning of going with "tropical" vs "subtropical" designation.

Hurricane Sam could be upgraded to Category 5 status in the Tropical Cyclone Report (TCR)?
