Wave/Low approaching 21N/50W

[Vortex]

Keep an eye on the circulation that moved off Africa days ago...This reminds me of Bonnie back in July. Void of convection but a decent envelope. The area of concentration is near 21N/48W this morning moving W/WSW. The globals in past runs move this system into the SE bahamas in 5 days or so..May be something to watch in the coming days as convection should increase as it passes just north of the islands...

TROPICAL WAVE EXTENDS FROM 24N44W TO 11N42W MOVING W AT 10-15
KT. NIGHT VISIBLE SATELLITE IMAGERY INDICATES WEAK LOW-LEVEL
CYCLONIC TURNING ALONG THE WAVE AXIS AND THIS WAS ALSO NOTED ON
SATELLITE DERIVED WINDS. AN AREA OF MAXIMUM DEEP LAYER MOISTURE
IS OBSERVED ON THE TPW IMAGERY EMBEDDED IN THE WAVE. HOWEVER...
MUCH OF THIS MOISTURE IS POSITIONED BENEATH A STABLE SAHARAN AIR
LAYER THAT COVERS MUCH OF THE CENTRAL AND E ATLC. THEREFORE...NO
SIGNIFICANT DEEP ORGANIZED CONVECTION ACCOMPANIES THE WAVE...
HOWEVER ISOLATED SHOWERS ARE WITHIN 20 NM WEST OF THE AXIS N OF
20N AND S OF 14N.

A link for those of you who want to track this year's storm killer. Watch the mid and upper level water vapor images. When the water vapor is no longer being absorbed by a SAL in the Atlantic, the hurricane season will resume its normal progress.

BTW, some of the images show some of the SAL reaching all the way into the G of M.
