Very cloudy over FL this morning.
Looks like minimal convection this afternoon.
Likely the ULL over it will stay in place.

Center appears to be west of that red circle. West of that convection.

Convective debris from the BoC ULL is taking out that LL Dry Air that 08L is going to be tracking into.

there are low level curved cloudlines going right through your location. it cant be there. it is just to the NE of that location.

Looking impressive watching the latest vis sat loops.. appears to be on the verge of TS status sooner rather than later.. very nice ll inflow, and some impressive convection building near the core ... system ready to launch IMO

this is coming together quite nicely.

nice MLC over top of the LLC convection building.

I would not go with global models on this one either..

TD8 is slightly better organized this morning....with several thunderstorms near the circulation center compared to the lone thunderstorm when it was upgraded last night. Should see slow intensification and could get upgraded to TS later today or tomorrow.....just going to bring more rain to Texas....MGC

Probably not the best scenario not to have recon out there.. lol

Surface obs all around the center indicate winds below 20 kts. Center is on the west side of the convection. It's a lot better-organized than it was yesterday. I'm wondering if there will be limited recon due to Hawaii flights added. I have a 45kt TS making landfall between Corpus Christi & Matagorda Bay around 9am Saturday.

They just started transmitting data, so they should take off any minute now.

Looks like we have a microwave pass now.

I was gonna say you can see the low level inflow pretty much in all directions. Find the middle of that and it would put the LLC around 90.3W and 25.7N. Which appears pretty inline with the microwave image.

A little closer cloud line mapping.. coming together pretty quickly now.

Still too far east. West of red circle. Recon will assist now.

Two months...

Maybe should have been a bit clearer. Meant when peak activity usually starts to significantly ramp up. But yes, if referring to the absolute peak, we are still several weeks away from that!

TD8 is in the process of building a more centralized structure, which will likely take most of today to complete. After that, there seems to be a trend to slow the storm down a bit in its approach to the coastline. Steering in the upper levels will favor more of a southerly component to TD8's motion, while mid levels will be more westerly. If TD8 does become deeper than anticipated, we could see it slow down along the coast and perhaps even dip a bit wsw near the coast.

Yeah, I think I read they were supposed to take off at 5:45?
