SYNOPSIS
THE PRESSURE GRADIENT BETWEEN THE ATLANTIC RIDGE AND
THE COLOMBIAN LOW WILL CONTINUE TO SUPPORT MODERATE TO FRESH
EASTERLY TRADE WINDS ALONG WITH MODERATE SEAS ACROSS MUCH OF THE
CENTRAL CARIBBEAN INTO EARLY SUN. FRESH TO LOCALLY STRONG WINDS
ARE EXPECTED TO PULSE OFF COLOMBIA AND THE GULF OF VENEZUELA
TONIGHT. IN ADDITION, MODERATE TO LOCALLY FRESH E WINDS AND
SLIGHT TO MODERATE SEAS WILL PREVAIL IN THE GULF OF HONDURAS
THROUGH SAT NIGHT. LOOKING AHEAD, A TROPICAL WAVE CURRENTLY IN
THE EASTERN ATLANTIC MAY BRING STRONG WINDS AND ROUGH SEAS TO
THE ATLANTIC WATERS EAST OF THE LEEWARD ISLANDS BY THE MIDDLE OF
NEXT WEEK.
