A surface high pressure system over the eastern to central Atlantic, interacting with a stationary frontal boundary north of the region, will promote light to gentle winds tonight. Pulses of northerly swell spreading across the Atlantic waters are maintaining seas around 5 to 6 feet across exposed areas, where small craft should exercise caution over the next several days. The combination of the front and the trough is increasing showers and thunderstorms across the local waters, creating locally hazardous marine conditions through at least midweek. Winds are expected to become gentle to moderate from the east to southeast from Wednesday onward. $$ AMZ711-150815- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 326 PM AST Tue Apr 14 2026 ...SMALL CRAFT SHOULD EXERCISE CAUTION... .TONIGHT...East winds 5 to 10 knots.
