Interesting that Belize City was still reporting NW winds at their last report, I would had thought that by now winds would had switch to at least NNE if center was to be SE of them.

Their last report was nearly three hours ago.

looks like the developing center is starting to move back onshore

I also am starting to think this has a good chance at doing something in the BOC... if it makes it there

Maybe a couple of hours old, they could be at central time.

Time there right now:
7:56pm Friday (CST) - Time in Belize

Here's a neat 24 hr SAT loop showing energy transfer from Alma across Honduras and forming this "new" LLC. Pretty cool when you speed it up really fast.

Convergence increasing just east of the center of low pressure.

Looks amazingly good on IR2 - large CCW motion, an emerging center, and hints of banding. I'm still shocked there's an invest on it though. Things like this are generally ignored in the Central Atlantic.

It would be really shocking to get 2 popup storms so early in the season.

Looking at the latest Visible I would say that a LLC is forming near 17.1 north/88.2 west. Near land as Derek says. I believe with the convection forming and the banding setting up, that if this had another 6-8 hours; this would be a depression. A well "Organized system" at the mid levels I would say. But it will not have the time to become anything more as Derek says, and I don't disagree. For one the Hurricane models show this system heading more westward, and if they are right then this thing is dead already. If some how this go's more northward it will have to start over again once in the BOC.

the dynamical models have something in the BOC, which is what I am basing my thoughts on.

The hurricane models... well... I am not really considering them in this instance

Pretty good winds and 8' waves out in the NW Caribbean, I am pretty sure is due to pressure gradient.

Which was that?


TD10.

It was the only model that had it dart NW into the panhandle of Florida. The rest had it going towards New Orleans.

I only have this image from before it traversed Florida, but yeah, it does show that NW dart

I disagree with the both of you, by watching at IR2 loop, it still looks like is offshore, moving very very little WNW or NW.

Here is my personal take on this system:

It is going to do what it wants to do.
