Marine Conditions:

The Caribbean Sea

Recent satellite derived wind data show moderate to fresh trades over the ABC Islands, near the entrance of the Gulf of Venezuela, and in the Gulf of Honduras, with mainly gentle to moderate winds elsewhere. Seas are 3-5 ft where the strongest winds are blowing with 1-3 ft elsewhere.

Showers and thunderstorms continue to flare-up over the Greater Antilles due to a combination of a tropical wave moving westward across the basin and an upper-level low currently located just S of eastern Cuba. A diffluent pattern aloft on the W side of the upper-level low is also helping to induce convection over most of Cuba and the NW Caribbean.

For the forecast, gentle to moderate winds will increase to moderate to fresh today, with strong winds pulsing during the overnights into the weekend offshore Colombia and in the Gulf of Honduras.
