You should hit the sack man, sleep good and wakeup to mass pessimism here, (rightfully so).


Can't do that, someone has to be at the office all night if it's upgraded, and I'm the only one available tonight. I can stay up 24+ hours, though I'd rather do it for a real storm.


Sorry to hear that, wxman57. Especially for this. I hope that at least they're paying you well. My job sure doesn't. :roll:

The ftp record for the renumber is interesting.

Could it be that the ULL over western Cuba is pulling in energy from this system? That's what seems to be happening on the loops - thoughts?

The Mex/Tex border area is no doubt unsettled by TD#2 :eek:
Stay safe y'all.

No. That's the southern end of flow from the large trough/upper low over the eastern U.S. and if anything, that flow is helping to enhance the equatorward outflow of the system.

ozonepete wrote:The big issue here is the same as it was with Alex. It started out as, and is still, a part of an elongated low pressure wave/trough. Elongated systems are (of course!) not circular, and non-circular or non-symmetric lows cannot allow for maximum vorticity into the center. The way this is racing northwestward without consolidating into a more circular system tells you that it can't ramp up. Alex was able to because it moved more westward out of the SE to NW flow - i.e. it moved westward out of the fast SE to NW flow and that allowed it to consolidate and develop. This one seems like it's embedded in that flow for good so it will never "break out of it" and become more circular.

But what I was trying to say before is that even though it will never break out of that SE to NW flow and has little time left, the NHC will probably have to issue TS warnings even if they don't think it will reach true TS, because in the right front quadrant you will have to add the forward speed of 10-15 mph on top of 25 to 35mph winds. That will cause TS winds at the coast north of the center. In effect, it will be a TS regardless of the storm relative winds.



That's why I made that post before. This is exactly what I thought would happen.

And BTW, it apparently is breaking away to the west from that trough, so it could get fairly strong...

I've seen more pathetic looking TC in the past so this is no suprize considering what recon found. Can't argue with recon baby! Too bad recon didn't sample 95L. TD 2 had better start producing some convection if it wants to grow into a big strong TS.......MGC

All Bonnie will do is add insult to injury after Alex.

Why even bother upgrading to a TD, it looks like hell. There's barely any convection and every image shows even more convection dying down. What a waste of a system.

You have to read the discussion (Advisories Thread) to see why they pulled the trigger.
