Yeah it appears to be one of those years where there are Vort/Swirls all over the place.

and they can randomly develop if they find the right conditions.

similar to 2005.

The amount of warming in the tropical Atlantic over the last few days is insane. The MDR has shot up to a mean +0.59 C anomaly, while the Caribbean has warmed up even more to +0.716 C...and both were running 0.0-0.2 C above average before this week.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

The SAL is expansive as would be expected this time of year. The GFS continues to show dry air everywhere across the MDR for the foreseeable future:

Also the MDR is leading the global tropics.

Indeed, SAL is pretty scattershot in coverage now away from the immediate African coast / Cabo Verde area.

SAL producing regions had some rain the last couple weeks. overall moisture will continue to increase across the MDR

Something to take notice of, over the past 30 runs of the CFS, there has been a slow correction for August VP anomalies propagation towards Africa:

Indeed, compared to just a few days ago dust has really come down some, but there's another one being forecasted next week but nothing close to earlier in the month, the western Atlantic Basin is mostly clear of any dust.

Hi Toad,

It's correcting towards a less hostile look.

There's definitely not a drop of dust in the western basin right now, nice tropical clean skies over central FL.

Hi Toad,

It seems relatively the same to me, I could be wrong.

Same here in T&T. This week is the first time in maybe weeks that I can actually look up into a clear, blue sky (and not a white sky, a light brown sky, a bluish-brown sky, etc).

The GFS has had a terrible history over the last few years in the Atlantic, with some exceptions obviously, of under-developing or simply not developing systems until a few days before they actually form--so this wouldn't surprise me in the least. I think they over-corrected the problem that was causing the Atlantic phantom storms.
