Nobody can affirm that Puerto Rico is clear from a potential impact of this system. I just got a bad feeling, and they should monitor this system closely!

I wonder if future 13L will be one of those rare systems with a M in its first advisory. I think only Tomas and Sam had a 100kt forecast point in advisory 1, but with the model guidance going absolutely nuts, this could be our next candidate.

I’ll be honest given the amount of models being very bullish with this I’ll be a bit disappointed if this doesn’t become a Cat 5.

If this develops tonight or tomorrow AM, difficult to go straight to NE Caribbean, even more hard to the PR area. I don’t see the thought of “the longer it takes to develop the more west it goes”…

I have a nice overview for this. Posted it with Larry and Sam, here is the updated version for the first advisory peak intensity. Based on NHC advisories since 1998 (of which the 1998 - 2002 advisories only went to +72 hrs).

Irma of 2017 was in the 80kt group as well. I'm actually surprised it wasn't more bullish, given the fact that it was already designated a 45-kt TS at the time advisories were initiated. However the advisory discussion did mention some adverse conditions coming up, and the soon-to-be infamous cyclone did indeed struggle with them for a couple of days before blowing up as it approached the Leewards.

Re: ATL: INVEST 95L - Discussion
This has such a good mid-level spin. It just needs some convection over the center to work that down to the surface and tighten it. Most of the deep convection over the last two days has been limited to the northern border of the circulation.

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.

Sam 2021 had a very similar feature before it formed, which went on to become a long-track 135kt C4.

Re: ATL: INVEST 95L - Discussion
Short term motion is kind of interesting. Obviously there is no distinct center yet, so it's not possible to confirm a specific heading. But it appears to be tracking straight W 270 degrees. The cluster of models including the TVCN blended guidance suggest that the storm should already be moving more WNW, and continue for the next 5 days. This matters for the Leeward islands.

Re: ATL: INVEST 95L - Discussion
Global and hurricane models suggest at a minimum this will be a very close call for the far northern Leewards. Ironic since the ghost of this year's edition is still pinwheeling around in the belly of zombie Franklin; but perhaps a Jose 2017-like track would be a close analog.

I agree with you. I’ve been watching the visible for signs of a center and it does appear to be moving much more westerly all day today. And we don’t have an official center which could complicate the starting point of the models especially if it pulls a fast one and forms toward the southern half. I don’t think they have the track wrong as it crosses the Atlantic but we most certainly don’t want early track errors to start a trend

ATL: INVEST 95L - Models
While you can never say never, I'm really liking today's trends of bringing the storm even further offshore than before, probably due to quick anticipated strengthening. Now we just need to get it East of Bermuda and we will be in good shape! Feeling much much better today than a few days ago that's for sure...I've loving all of these storms moving out to sea. The one we had in Florida as enough for the year........

Re: ATL: INVEST 95L - Discussion
Believe me, I am watching from PR closely every motion 95L is doing as it will be important down the road. I am sure our friends in the Leewards and Virgin Islands are also watching.
