That is an upper low.

[cycloneye]

A VIGOROUS UPPER LEVEL LOW IS LOCATED ABOUT 180 NM ENE OF
TRINIDAD NEAR 12N59W WITH AN INVERTED TROUGH EXTENDING N TO
20N60W...MOVING QUICKLY W TOWARDS THE WINDWARD ISLANDS AND
EXPECTED TO CROSS IN THE E CARIBBEAN SAT MORNING. THE LOW IS
PRODUCING DRY WEATHER ACROSS THE LESSER ANTILLES BUT TSTMS ARE
LOOMING TO THE E WITH SCATTERED MODERATE CONVECTION FROM 8N-12N
BETWEEN 53W-60W ON THE DIFFLUENT S/E SIDE.

The above is the 8 PM Discussion about the upper low.
