BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1715 UTC.

...TROPICAL WAVES...

TROPICAL WAVE IS ALONG 50W S OF 16N MOVING W 10-15 KT. FOR THE
PAST FEW DAYS THERE HAS BEEN SOME CONFLICTING EVIDENCE ON THE POSITION OF THIS WAVE. WE HAVE MAINTAINED CONTINUITY FOR THE PAST COUPLE OF DAYS FOLLOWING A FAINT LOW-LEVEL INVERTED V-SHAPE IN THE LOW CLOUDS WELL AHEAD OF DENSER CLOUDINESS. HOWEVER...
THAT WEAK LOW-LEVEL SIGNATURE HAS JUST ABOUT DISSIPATED AND THE DENSER CLOUDINESS HAS BECOME MORE PRONOUNCED WITH SOME WAVE LIKE STRUCTURE EVIDENT. A LONG-TERM SATELLITE LOOP AND THE MIMIC TPW ANIMATION ALSO SHOWS WWD PROPAGATION OF THIS CLOUD MASS.
THEREFORE...THIS WAVE WILL LIKELY BE RELOCATED BACK FIVE DEGREES OR SO TO AGREE WITH THE SATELLITE SIGNATURE. SCATTERED MODERATE CONVECTION IS FROM 5N-13N BETWEEN 39W-47W. :wink:
