I have it moving toward TX Mon/Tue, dipping SW then turning E-ENE Wed-Thu (70kt hurricane at day 7). Would rather it just move inland into south TX or Mexico early next week. That could happen...

This has escalated a good deal today and what appeared as an elongated COC this morning, now appears to have developed a fairly tight LLC. I hadn't heard if recon will get there soon but if so, I'm pretty sure we'll have a T.D. at 5:00pm


Buoy 42055 near the center had one wind gust near 38 knots so could be named but with spaghetti model runs who needs the headaches?

VERY unlikely - I have 20 gallons of gas stored in the backyard getting ready for Laura. It knows I'm too prepared to come here. Recon found a little swirl down there, which has been evident. Not enough to call it a TD in my opinion, but who knows what the folks at the NHC are thinking? Winds under 30 kts.

Buoy to the east definitely NOT supportive of an upgrade to a TS. It indicates a weak LLC is present.

Not 57, but I do think SETX could see considerable rainfall from this.

I sure HOPE we get some rain out of it, but I'm not sure we will get anything out of it.

Looks very weak, and the center looks a tad broad to me.

It is a broad surface reflection for the time being, but I think it is enough to classify it as a TD.

Convection looked better earlier and might even have briefly been a TS but thats not uncommon with developing TCs.
If this isn’t given TD22 tonight, I’d bet alot that it could actually become a stronger TS by morning after DMAX.

I can't see why they would not go with TD

I agree with you. There is sufficient evidence this is a TD. Recon also finding winds nearing TS force as well.
