From NHC TAFB:

CENTRAL ATLC TROPICAL WAVE ALONG 32W/33W S OF 22N MOVING W 15-20
KT WITH A 1014 MB LOW ALONG THE WAVE NEAR 11N. THE LAST VISIBLE
SATELLITE PICTURES SHOWED A LARGE CIRCULATION ASSOCIATED WITH
THE WAVE WITH NO WELL-DEFINED CENTER. A RECENT QUIKSCAT
CONFIRMS THE LOCATION OF THE LOW THOUGH WINDS ASSOCIATED WITH
THE FEATURE ARE LESS THAN 20 KT. THERE IS A BIT OF DRY AIR
ENTRAINED INTO THE NORTHERN PART OF THE WAVE THAT IS PROBABLY
INHIBITING DEVELOPMENT AS ANY TSTMS HAVE BEEN WEAK AND
SHORT-LIVED. HOWEVER CONVECTION HAS BEEN INCREASING A LITTLE
TONIGHT NEAR THE CENTER WITH WIDELY SCATTERED MODERATE
CONVECTION FROM 8N-12N BETWEEN 33W-40W. COMPUTER MODELS SUGGEST
VERTICAL WIND SHEAR WILL REMAIN LOW AS THE WAVE MOVES WESTWARD
AND THE WAVE MAY HAVE SOME POTENTIAL FOR DEVELOPMENT AFTER IT
ENTERS WARMER WATERS W OF 40W.
