Bobbi, you get your answer from the Discussion:

ALTHOUGH THE DEEP CONVECTION IS NOT AS IMPRESSIVE AS IT WAS
EARLIER...SURFACE OBSERVATIONS FROM THE ISLANDS OF TRINIDAD AND
MARGARITA SHOW WEST-SOUTHWEST AND WEST-NORTHWEST WINDS OF AROUND 10
KT RESPECTIVELY. SINCE THERE IS NOW A DEFINITE CLOSED CIRCULATION
AT THE SURFACE...THE SYSTEM NEAR THE WINDWARD ISLANDS IS BEING
NUMBERED AT THIS TIME. VISIBLE IMAGERY DEPICTS A VERY
WELL-ORGANZIED SYSTEM WITH DISTINCT BANDING FEATURES. THE
UPPER-LEVEL ENVIRONMENT IS EXPECTED TO REMAIN FAVORABLE THROUGH THE
FORECAST PERIOD...SO GRADUAL STRENGTHENING IS SHOWN IN THE OFFICIAL
FORECAST. THIS IS SOMEWHAT LESS THAN THE SHIPS GUIDANCE.
