Meteorological authorities across the Eastern Caribbean have issued urgent warnings as significant ocean swells pose severe threats to northern coastlines. The Antigua and Barbuda Meteorological Service activated a high surf advisory Tuesday afternoon, alerting residents and visitors to hazardous marine conditions expected to persist through the weekend.
The advisory specifically targets exposed northern and north-facing shorelines across multiple territories. Forecast models indicate powerful wave systems generating swells of 2-3 meters (6-10 feet), with sea conditions occasionally reaching 4 meters (13 feet). These formidable waves are accompanied by long-period swells averaging 10 seconds, significantly elevating the risk of deadly rip currents throughout the region.
Impact timelines vary across the archipelago: Antigua and Barbuda face hazardous conditions from Wednesday morning through Saturday midday; St. Kitts and Nevis from Wednesday morning through Sunday night; Montserrat from early Wednesday through Sunday night; Anguilla from Wednesday morning through Saturday morning; and the British Virgin Islands from Wednesday morning through early Saturday.
The meteorological service outlined multiple potential consequences including significant beach erosion, coastal flooding, dangerous sea splash onto low-lying roadways, and possible damage to sensitive coral ecosystems. Marine businesses may experience operational disruptions, while desalination facilities could encounter saltwater intrusion issues.
Authorities strongly recommend avoiding affected beaches and rocky shorelines entirely, particularly remaining clear of exposed jetties and reef areas. Swimmers are advised to use only sheltered southern beaches with lifeguard supervision present. For those caught in rip currents, safety guidelines emphasize remaining calm, floating rather than swimming against the current, and attempting to move parallel to shore while signaling for assistance.
