This is not the right kind of trend in steering you want to see if you expecting a turn to the wnw/nw.. lol

WNW is actually 285 to 300, which can be checked here. And it's already heading WNW, according to the latest advisory.

EDIT: As Aric rightly pointed out, he said "more" WNW.

It's still being hit by shear. The LLC is just outside the convection to the SE. Crosshairs are at 13.6N/47.9W. NHC's position 3 hours ago was 12.9N/47.9W. It hasn't moved due north. Center was hard to locate using IR imagery.

I said it needs to turn "MORE" towards the wnw .. meaning the upper end ..

the center 2.5 hours ago just before it was pulled completely under the CDO easily found.

1.5 hours ago. losing it under the convection.

So extrapolating to Current satellite image.. following the curved band that is developing. the center is a good deal west of your position fully under the convection.

Definitely a lot more organized this morning, as GCANE mentioned, all it takes is a bit more convection to wrap around to establish an outflow channel and an anti-cyclone, once that happens, it's off to the races.

Pretty obvious from the cirrus outflow that the UL jet is gone and a convection anticyclone is in place.
There may be a bit of shear evident east of the CoC at mid levels.
Inflow is developing rapidly as seen be the convective burst to the NE.
Being under the AWB is doing wonders and should put an end to any shear shortly.

If there's an LLC under there it's not very vigorous. Low level clouds on south side moving south, not east.

Conditions for the next week or so are not favorable so if this does become a tropical storm I think it will be over performing.

more organised this morning but I find it doubtful that ASCAT will find 35kt winds this afternoon, not unless it maintains this convective burst until tonight.

Center still appears to be near the SE edge of the convection.. Oh, I'm sure it'll be upgraded to Josephine today, and it'll be torn apart within 48 hrs.

yeah it is well on its way. a little re-orginization happened as the center was pulled to the WNW under the convection.. but the multiple feederbands are a dead giveaway.

Looking the best it ever has this morning, doesn't say much though. I expect an upgrade at 11am but likely wont last long.

Ah yes. My mistake. Alas! I've become a victim of the short-attention-span malady so common these days. :oops:

A possible stay of execution?

48 hrs out and hitting the shear.
But wait, there's an anticyclone, and it could be all an outflow channel.
355k PV is in the clear.
