It should had been an invest much earlier, since it will be moving into much cooler waters really soon.

[Matt-hurricanewatcher]

System taking off fast, but LLC is refocusing on or near the southern Part of the convection. This is pretty organized overall.

[Coredesat]

I really have no earthly idea why this is an invest...it's about to be absorbed by a front and is only firing convection due to the unstable air ahead of that front. It will be gone soon enough.

[Matt-hurricanewatcher]

Why because it has a LLC with convection near it, now we can discuse is it a tropical cyclone or not. But its a invest at least.

NRL has it at 40 knots. Also the LLC is on the southwest edge of the convection...

I don't see "40kts".

[Coredesat]

That LLC (or lack thereof, QS doesn't show a closed circulation) is quite elongated, actually.

[Matt-hurricanewatcher]

Many a storm over the last 5 years have been missed by the quickscat. The system has a LLC or at least a broad elongated one. But ok lets just say good bye to the good or half way good looking system.

The QS this morning showed a broad and elongated surface low as well. And ship obs and visible images seemed to confirm that. On latest visible images, I can't make out another LLC forming closer to the convection, but that is not to say that it can't do that.

The system has a little more time to organize, and is going to be moving over warmer water soon, but it's fighting alot of shear and it may merge with the front off the coast later today. I think TPC labeled this invest because they want more ship reports in the area.

[Matt-hurricanewatcher]

I will keep looking, I just don't like these kinds of systems. These are in between systems; they make people fight over every thing. Really the old LLC at least the broad on is becoming very elongated from south to north. "if" there is a new one it would be just under the convection on the southwest side. I say it has about 6 hours.

This clearly doesn't look tropical to me. I don't know why the NHC decided to name it an Invest.

[hcane]

The NHC has not named it 91L ... just the NRL ....

[bayway]

well.. no one is nameing this system anything. It's not a named storm.
they are simply stating that the system is worth inverstigating.

[hcane]

sorry for the mistake ... whatever IT is has not been stated as having been listed by the NHC as anything that they are investigating
