I was thinking that too ....more yesterday than today.

If there was a "center" I think it took off towards the North and it's hard to find.

The lower level moisture is oozing west...

An area in the SW Carib seems to be "blossoming" and also adding to shear from below... the trough to the north is racing down towards it... looks bleak for the wave that caused so much weather in PR and the islands yesterday.

It had the appearance the other day of something happening.. then lost it.

And, I don't think that can be blamed completely on African Dust...

A wave needs to be stacked to properly develop... which was a problem with Debby whose weather always stayed far from her center. This wave needs a center.

Either way... what you said definitely can be seen played out on long loops.

Great discussion out of Key West NWS:

".A WAVE IN THE
EASTERLIES IS ANALYZED ABOUT 500-700 MILES SOUTHEAST OF THE FLORIDA
KEYS...WITH A WAVE AXIS RUNNING FROM NEAR GRAND TURK TO JAMAICA. THIS
WAVE WEAKENED CONSIDERABLY DURING THE LAST 48 HOURS AS IT APPROACHED
THE LARGE DIFLUENT ZONE ALONG THE SOUTHWESTERN FLANK OF THE
SUBTROPICAL RIDGE"

See what today brings...

Wondering how much the area in the SW Carib is affecting it as well now..
