Nice point on that.. I probably should of said No tropical development instead of activity.
I agree and see they also talk about the difflent pattern aloft like i mentioned.

A TROPICAL WAVE ALONG 85W S OF 20N MOVING W 10 KT. SATELLITE
IMAGERY SHOWS WEAK LOW LEVEL CYCLONIC TURNING N OF 16N. THE WAVE
IS PRODUCING SHOWERS AND A FEW THUNDERSTORMS OVER THE NW
CARIBBEAN AND PARTS OF CENTRAL AMERICA...MAINLY OVER NICARAGUA.
SIGNIFICANT DEVELOPMENT OF THIS SYSTEM IS NOT ANTICIPATED. A
DIFFLUENT PATTERN ALOFT IS HELPING TO ENHANCE THIS CONVECTIVE
ACTIVITY. ACCORDING TO THE GFS MODEL...MOISTURE FROM THIS WAVE
SHOULD AFFECT BELIZE AND THE YUCATAN PENINSULA SAT AND THE BAY
OF CAMPECHE SUN.

CARIBBEAN SEA...
BROAD UPPER RIDGE DOMINATES THE BASIN ANCHORED ON A HIGH LOCATED
SOUTH OF JAMAICA NEAR 15N77W. WATER VAPOR IMAGERY SHOWS ABUNDANT
MOISTURE STREAMING NORTH FROM CENTRAL AMERICA ACROSS THE WESTERN
CARIBBEAN INTO CUBA AND THE FLORIDA KEYS. DIFFLUENCE ASSOCIATED
WITH THE RIDGE IS ENHANCING THE CONVECTIVE ACTIVITY NEAR THE
TROPICAL WAVE ALONG 85W. 20 TO 25 KT TRADE WINDS ARE BLOWING
OVER A LARGE PORTION OF THE BASIN W OF 70W. WINDS HAVE DECREASED
FROM AROUND 30 KT NEAR THE COLOMBIA COAST YESTERDAY. THESE
MODERATE WINDS ARE EXPECTED TO PERSIST AND WILL INCREASE AGAIN
SUN THROUGH TUE AS THE ATLC RIDGE NORTH OF THE AREA STRENGTHENS.
SHOWERS AND A FEW TSTMS ARE CONCENTRATED ALONG AND NEAR THE
COAST OF HONDURAS AND NICARAGUA IN ASSOCIATION WITH THE TROPICAL
WAVE. TRADE WIND SHOWERS...CHARACTERIZED BY THEIR SHORT DURATION
AND LIGHT INTENSITY ARE SEEN OVER THE E-CENTRAL CARIBBEAN.
