I don't know, but this looks like a tropical cyclone has formed.

It spit out a few outflow boundaries on the NW side. Still a vigorous MLC it looks like but weak at the surface. I expect that will quickly change tonight with DMAX.

This has to be at least a TD, this is kinda ridiculous.

That relatively small and compact white ball spinning on the south side sure looks lower level to my untrained eyes. Maybe someone can give some facts and figures to say why its not so. I am obviously an untrained observer.

Yeah plnety of evidence to make the case for closed surface circ. two fairly well definded circ are quite easy to see. surface obs also point to it being closed. if that vort develops convection over the next few hours. then its very highly likely that a TD/TS

This is NOT a TD or a TS. The convective blowup from this morning is now mainly cirrus. The next one, which should occur overnight, will form the cyclone.

Just need some patience. This could end up as a 3 in the Gulf. Some many similarities to Karl, expect toward Tampico instead of Veracruz

You can see it slowly tightening up but still has a little ways to go.

Perhaps not as much red as you would like to see, but it does look like there is rotation in the precip. Will be patient.

Future Franklin will likely make a run at major hurricane status, no surprise since the BoC and Western Caribbean seem to be the only favorable spots in town right now in the Atlantic.

If a plane was out there it would very likely find a closed circ. bu as we know the NHC like to be on schedule. :)

looks well on its way. Assuming this goes into the BOC->Mexico this would make yet another BOC->Mexico system 7 out of the last 8 seasons.

And those have been quiet seasons for the US mainland. A pattern....will this year break the mold (US mainland)?? Just coincidence, probably...not indicative of any larger meaning.

The Yucatan peninsula will take some steam out of TD7 and it would take at least 48 hours in the BOC to reach major hurricane status. Definitely looks like Franklin though.

Ehh, I wouldn't call it closed when using the 25 km ASCAT data from METOP-A.
