High surf warning will take effect Tuesday across several islands. The alert covers Antigua, Barbuda, Anguilla, and the British Virgin Islands.

According to the Antigua and Barbuda Meteorological Services, conditions will worsen quickly. The warning begins Tuesday morning. It will remain in place until Thursday.

Meanwhile, the focus is on exposed coastlines. Northern and north-facing shores face the highest risk. Reefs and shallow nearshore areas are also vulnerable.

Forecasters say long-period swells are approaching the region. These swells will create dangerous marine conditions. As a result, the threat level remains high.

In particular, waves could become life-threatening. Surfs may exceed 3 metres, or 10 feet. In some areas, waves could rise even higher.

Additionally, sea conditions will remain rough. Wave heights may range from 2.1 to 3.0 metres. At times, they could reach near 4.0 metres.

Moreover, swell periods will range from 10 to 13 seconds. These patterns increase the risk of powerful surf. Consequently, rip currents are likely.

Officials warn that rip currents can be deadly. They can pull even strong swimmers out to sea. Therefore, extreme caution is necessary.

At the same time, coastal flooding is possible. High tides combined with strong swells may impact low-lying areas. Beach erosion is also expected.

Furthermore, waves may affect roads and coastal structures. Sea water could splash onto roadways. In addition, harbours may become unsafe.

The warning also highlights wider impacts. Marine businesses could face disruptions. Beach closures may occur. Financial losses are also possible.

Environmental damage remains a concern as well. Coral reefs could suffer harm. Saltwater intrusion may affect potable water systems.

Given these risks, officials urge strict precautions. No one should enter affected waters. People should also avoid rocky shores and coastal structures.

If caught in a rip current, experts advise staying calm. Float and avoid swimming against the flow. Instead, move along the shoreline if possible.

Overall, the warning signals serious danger. Residents and visitors should remain alert and follow all safety advice.
