ATL: HARVEY - Post-Tropical - Discussion

[RL3AO]

Just curious why has the NHC not labeled this potential TC at this point?

Because it's not close enough for watches to be issued.

not expected to make landfall within 48 hours

NHC won't issue PTC advisories on the remnants of named storms.

Can someone explain how it's possible for a system to not only maintain a TS as far north as San Antonio, but strengthen as well? Does this not seem incredibly absurd to anyone else?

That's more or less what Tropical Storm Hermine did in 2010.

Thanks, I had forgot about that requirement for the designation. I figured it would be "Potential TC Harvey" or something similar if that were to occur.

Impressively quick organization going on at the moment, in my opinion.

Based on latest GOES-16 imagery, possible CofC about 21 north, 91.5 west ... whaddya think?

[GCANE]

Took a little longer than I thought, but the pop ups across the Yucatan are starting to fire due to solar heating of the ground.
Should start to see a big MCS develop tonight and move out into the BoC.
IMHO, once the CoC moves directly south of the ULL's center, convection should get more intense for a sustained per of time.

[KWT]

Yes fairly impressive speed with which the convection is developing and starting to wrap around itself as well, doubt it will be long before it is a TD again, looking good for the more aggressive models (gotta be said, the models have been dreadful by in large for this one.)

[hd44]

Mid level RH is lacking right now, needs to moisten the environment a bit .

NEXSTAT provides a good SAT imagery loop. Looks to be organizing:

nice link and easier t load than the SLIDER...thanks!!

[TheStormExpert]

Like hd44 said RH seems to be lacking some probably in thanks to that ULL in the NW Gulf. This is why convection is limited at best.

[Blinhart]

So is there a good chance of RI once this does get consolidated? The water is warm enough, just don't know if the Upper levels are good enough for it.

[Frank P]

Initial banding features developing?

That's what I am seeing, but much improved conditions in 2 days as per the Gfs .

[Kingarabian]

Frank, do you think that's the start of a broader circulation that the models are depicting?

[TeamPlayersBlue]

Well i think its quite clear the center, although kind of broad, is now offshore and into the Gulf. It's go time for this system.

[Digital-TC-Chaser]

Strong wave.

[NDG]

Coming together fairly good.
