From the latest Atlantic Tropical Wx Discussion...

HIGH-AMPLITUDE TROPICAL WAVE OVER THE CENTRAL ATLC ALONG 42W S
OF 22N WITH A 1011 MB LOW ALONG THE WAVE NEAR 16N MOVING W 15
KT. THE LOW IS BETTER-DEFINED THAN YESTERDAY WITH HINTS OF
BANDING BEGINNING TO FORM IN THE N SEMICIRCLE. CONVECTIVE
REMAINS MODERATE WITH WIDELY SCATTERED MODERATE FROM 15.5N TO
20N BETWEEN 39W-42W. A LARGE TROUGH SEEN ON WATER VAPOR IMAGES
ALONG 50W SHOULD INDUCE A MORE POLEWARD MOTION TO THE LOW WITHIN
THE NEXT 24 HOURS. COMPUTER MODELS SUGGEST THAT THIS AREA COULD
BECOME THE NEXT TROPICAL CYCLONE AS IT TREKS OVER THE OPEN
OCEAN... THOUGH UPPER WINDS ARE MARGINAL.
