Who said poof? I see convection firing. Still bears watching.

there is a surface low forming near roatan island just off shore hondorous
out of all the mess over the past few days this mess!! has the most promise... it has the the strongest low level cuvature and a better pressure field .. there is a ship right near swan island with a pressure of 1007 mb.
and there is a small upper anti cyclone almost over it .. but very hostile as you enter into the gulf ....
reminds me of alberto last year .. almost the exact set up

You're looking in the wrong area. Look farther north in the NW Caribbean to the southern Gulf for this disturbance. Moisture will be streaming northward into an upper trof/low across the north-central Gulf over the next 24-48 hours. That's where the low may form. But it'll be in a high shear environment, more of a hybrid low. Probably sub-TS force winds. Beneficial rain for Florida though, possibly. May not be organized enough for NHC to worry about it, but wouldn't rule a TD or STD out.

Euro seems to agree with you or viceversa.
Seriously, I think the euro is right on the money for right now.

oh wait maybe this will help you see where the low is forming as i said

I have also found some south and Sw winds on the honduras coast http://weather.noaa.gov/weather/HN_cc.html
also the island roatan and the one next to it ( quanaja to its east) have North and then SW
so the Low is and has been trying to get going in that area all day

How do you read that map with the numbers going from 1to 5 or viceversa.

Notice the barometric pressure is dropping at Roatan off Honduras.

Gfs,Gfdl develops a low pressure. Both track it from that blob in the western caribbean south of Cuba. This reminds me of Alberto, yes high shear to its north, but overall shear around the system its self is decreasing at 10 knots. Which is another sign...The Cmc shows a fairly organized system; maybe a strong tropical storm/subtropical storm?
