Residents were urged to prepare for a potential hurricane as the weather system was expected to near Bermuda this week.

Tropical Storm Ernesto, previously known as Potential Tropical Cyclone Five, was situated in the southern Caribbean when the Bermuda Weather Service issued its 6pm update, with maximum sustained winds of about 46mph.

The system was travelling west-northwest at about 28mph and was forecast to move across portions of the Leeward Islands and St Kitts & Nevis tomorrow.

By early Wednesday morning, Ernesto was expected to strengthen into a strong tropical storm and move over the US and British Virgin Islands and Puerto Rico.

The storm was then forecast to become a hurricane by early Thursday morning and reach Category 2 strength by Saturday.

Ernesto, which strengthened into a tropical storm this afternoon, was expected to be about 500 miles south-southwest of Bermuda on Thursday, when it was predicted to be at its closest point of approach within the next three days.

However, the BWS warned that the system could come closer to the island later in the week.

Tracking forecasts suggested that the system will swing north and make a beeline for Bermuda by Saturday.

The US National Hurricane Centre said today that tropical storm warnings were in effect for the Leeward Islands, the Virgin Islands and Puerto Rico.

It added: “It is too soon to know what impacts Ernesto could bring to Bermuda later this week, and interests there should monitor the progress of this system.”

Michael Weeks, the Minister of National Security, said that his ministry was working with the Emergency Measures Organisation to monitor the storm.

He also reminded the public that while the system did not pose an immediate threat, “it is crucial that we remain vigilant as it approaches us”.

Mr Weeks added: "The EMO has scheduled a meeting of its executive team for Wednesday to ensure that all relevant agencies are fully prepared for any potential impact this weekend.

"We urge all residents to begin their storm preparations now.

“Please ensure that your properties are secure by removing loose debris and outdoor furniture, checking on your neighbours and the elderly to ensure that they are prepared and informed, stocking up on necessary supplies, including medicine, and making arrangements to secure pets.

"For those with boats, please make arrangements to secure them in advance.

“Additionally, it is critical that residents review and update their home insurance policies, ensuring that both home contents and property damage are covered.

“While it is natural to feel that the storm may change course or diminish in intensity, we must not underestimate its potential threat.

“Hurricanes can be unpredictable, and it is crucial that we take the necessary steps to prepare now rather than face the consequences of being unprepared.

"Your safety and the safety of your loved ones depend on it.

“Do not wait until it is too late; act now to protect yourself and your community."

Belco reminded the public of its storm guide and safety tips over the company’s X account.

It posted: “We encourage everyone to prepare and ensure their properties and belongings are secure and safe as a precaution in case this disturbance becomes a threat.”

There have been two hurricanes and three tropical storms since 2024’s hurricane season started in June.

Hurricane Beryl tore through the Caribbean last month, hitting Grenada as a Category 4 on July 1 and circling around the Gulf of Mexico before reaching Texas and travelling north to Michigan before dissipating.

The damage to Grenada motivated countries around Caricom, including Bermuda, to offer aid.

Hurricane Debby hit Florida on August 5 and travelled along the East Coast before dissipating over Canada.

Despite weakening into a tropical storm immediately after passing over Florida, the storm unleashed floods and tornadoes, and has so far claimed seven lives and created about $12 billion worth of damages.
