The Antigua and Barbuda Meteorological Services has issued a high surf advisory for the twin-island nation and parts of the Eastern Caribbean, warning of life-threatening conditions along northern and eastern coastlines.

This advisory comes on top of a small craft advisory already in effect through midnight.

Meteorologists say moderate long-period swells are generating dangerous surf, with wave heights of 7 to 10 feet—occasionally reaching 12 feet—especially along north and east-facing shores. Swells are coming from the north and northeast at 5 to 6 feet and higher in places.

The high surf advisory remains in effect until:

• Saturday afternoon for Antigua
• Saturday evening for Barbuda, Anguilla, and the British Virgin Islands
• Friday evening for St. Kitts

The threat level is moderate, with risks including strong rip currents, beach erosion, injuries, and seawater on low-lying roads. Localized flooding is also possible during high tides.

Beachgoers are urged to exercise extreme caution, avoid northern shores unless lifeguards are present, and stick to sheltered southern beaches. If caught in a rip current, officials advise floating, swimming parallel to shore, or calling for help if unable to escape.
