Hurricane Erin intensifies to category 4 as it nears Caribbean

Erin strengthened into a powerful Category 4 hurricane in the Caribbean on Saturday (August 16, 2025) and continues to intensify, the National Hurricane Centre said.

The storm is currently 240 kilometres northeast of Anguilla with maximum sustained winds of 230 kph. It is moving west-northwest at 31 kph.

It is currently not forecast to hit land, but strong winds are affecting nearby islands, prompting forecasters to warn of possible flooding, landslides and mudslides. The Hurricane Centre said it will eventually swerve away from the continental United States.

Tropical storm watches are in place for St Martin, St. Barts and St. Maarten.

“The outer bands of Erin are expected to produce areas of heavy rainfall through Sunday (August 17, 2025) across the northern Leeward Islands, the Virgin Islands, and Puerto Rico,” the centre said. The currently “compact” storm is expected to grow in size in the coming days, resulting in rough ocean waters over the western Atlantic.

Hurricane specialist and storm surge expert Michael Lowry said Erin is forecast to eventually take a sharp turn northeast that would put it on a path between the U.S. and Bermuda.

“All of our best consensus aids show Erin turning safely east of the United States next week, but it’ll be a much closer call for Bermuda, which could land on the stronger eastern side of Erin,” he said.

Protruding U.S. coastal areas — such as North Carolina’s Outer Banks, Long Island, New York, and Cape Cod, Massachusetts — face a higher risk of direct and potentially severe tropical storm or hurricane conditions than much of the southern Atlantic, mid-Atlantic and northern New England coasts, Accuweather said.

Erin is the fifth named storm of the Atlantic hurricane season, which runs from June 1 to November 30, but the first to reach hurricane status.

This year’s season is once again expected to be unusually busy. The forecast calls for six to 10 hurricanes, with three to five reaching major status with winds of more than 177 kph.

The U.S. Government has deployed more than 200 employees from the Federal Emergency Management Agency and other agencies to Puerto Rico as a precaution as forecasters issued a flood watch for the entire U.S. territory from late Friday into Monday.

Puerto Rico Housing Secretary Ciary Perez Pena said 367 shelters have been inspected and could be opened if needed.

The U.S. Coast Guard said Friday (August 16, 2025) that it closed six seaports in Puerto Rico and two in the US Virgin Islands to all incoming vessels unless they had received prior authorisation.

Meanwhile, officials in the Bahamas said they prepared some public shelters as a precaution as they urged people to track the hurricane.

“These storms are very volatile and can make sudden shifts in movement,” said Aarone Sargent, managing director for the Bahamas’ disaster risk management authority.
