What was the LLC currently looks stretched out. Looks like it might be getting sucked under the convective blob. IDK either that circ will have to redefine itself or a new circ will have to take over under the convection for this to get classified I think. But it has time I think we get Josephine out of this

90/90 in the latest TWO! The NHC says that advisories on a TD could be initiated later today if its organizational trend continues.

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.

06Z GFS forecasting dry-air entrainment to begin in about 50 hrs.
We will see how well this is a protected pouch then.
It'll depend on mesoscale effects which GFS can't effectively model due to spatial-resolution limitations.

50 hrs out, GFS shows UL winds abating due to Anticyclone Wave Break directly to its north.
TUTT farther away to the NE.
Strengthens then as the anticyclone moves over the CoC.
Watching closely how well this protects itself from SAL.

Too far out to call what may happen in the Bahamas come early next week.
There are indications something may develop off the east coast then due to a stalled front.
The whole dynamics of the forecast will be dramatically altered if that happens.

That convection is fool's gold. No upgrade until at least tomorrow AM. It needs to rebuild

I think that’s the old LLC dying with a new one developing underneath. But the waning convection has me a bit skeptical. Not sure we see 11L at 11

I agree that LLC has no future, but I don't see a new one developing. Not much of a future for this disturbance.

IMHO there is enough convective debris to pinch off SAL, enough LL vort, enough warm core, and enough TPW infeed to get this to start pulsing.
Watching if the next pulse, if and when that may occur, will be closer to the CoC.

Sounds like Alex doesn’t want to wait until after the 20th but that’s looking like reality as this will die out due to SAL and mjo stability

Is it just shear that causes dissipation or is it also dry air?

Gotta satisfy that "hyperactive" prediction! 2005 was like that too - every little wisp with some spin was given a name. There were 3-4 "Tropical Storms" that lasted <24 hours.

Looks like the LL Center is east of the 700mb wave peak.
It appears the two will align in 24 hrs.
This is currently SE of an Antycyclonic Wave Break.
The AWB is forecast to move south somewhat in the next 24 hrs as the CoC gets directly south of it.
This should improve chances for development as long as this can stay protected from SAL.

I would not accuse the NHC of falsely trying to pump up the numbers. However, the requirements for what qualifies as a named storm have changed significantly during my 40+ years as a hurricane forecaster.

The ability of obtaining the qualifying data has changed as well I'd confidently assume. I guess looks can be deceiving? I dunno....
