Scattered thunderstorms are also noted south of Hispaniola and west of the Windward Islands. A weak pressure gradient across the Caribbean results in moderate to locally fresh trades, with the strongest winds found within 100 nm of N Colombia and NW Venezuela based on overnight scatterometer satellite pass. Seas of 3-5 ft are present in the central and SW Caribbean, while 1-3 ft are occurring in the E Caribbean and 1-2 ft elsewhere.
