Hurricane Erin explodes in strength to a Category 5 storm in the Atlantic near Caribbean Islands

Hurricane Erin exploded in strength to a Category 5 storm in Atlantic waters just north of the Caribbean on Saturday (August 16, 2025), rapidly powering up from a tropical storm in a single day, the National Hurricane Centre said.
While the compact hurricane's centre was not expected to strike land, it threatened to dump flooding rains in the northeast Caribbean as it continued to grow larger.
The first Atlantic hurricane of 2025, Erin ramped up from a tropical storm to a Category 5 hurricane in a mere 24 hours. By late Saturday morning, its maximum sustained winds more than doubled to 160 mph (255 kph).
Mike Brennen, director of the National Hurricane Centre in Miami, said Erin grew into a 'very powerful hurricane,' with its winds gaining 60 mph (96 kph) in about nine hours.
'We expect to see Erin peak here in intensity relatively soon,' Mr. Brennan said in an online briefing.
The Hurricane Centre said Erin should weaken somewhat late Saturday or early Sunday as the storm encounters increased wind shear and possibly takes in more dry air. However forecasters predicted that it will remain a major hurricane until midweek.
Erin close enough to land to trigger flooding, landslides
The hurricane was located 110 miles (180 kilometres) north of Anguilla at Saturday afternoon and moving west at 16 mph (26 kph). The storm's centre was forecast to remain at sea, passing 145 miles (233 kilometres) north of Puerto Rico, according to the National Hurricane Centre.
Tropical storm watches were issued for St. Martin, St. Barts and St. Maarten, and the hurricane centre warned that heavy rain in some areas could trigger flash flooding, landslides and mudslides.
Tropical-storm force wind gusts were possible in the Turks and Caicos Islands and the southeast Bahamas.
Though compact, with hurricane-force winds extending 30 miles (45 km) from its centre, Erin was expected to double or even triple in size in the coming days.
Powerful rip currents could affect the U.S. East Coast from Florida to the mid-Atlantic next week, despite the eye of the storm forecast to remain far offshore, Mr. Brennan said.
An incredible' race from tropical storm to Category 5
Hurricane specialist and storm surge expert Michael Lowry said Erin gained strength at a pace that was 'incredible for any time of year, let alone August 16th.'
Mr. Lowry said only four other Category 5 hurricanes have been recorded in the Atlantic on or before Aug. 16.
The most powerful storms tend to form later in the year, with the hurricane season typically peaking in mid-September.
In October 2005, Hurricane Wilma rocketed from a tropical storm to a Category 5 in less than 24 hours, according to National Hurricane Center advisories from that time. Wilma weakened to a Category 3 hurricane before striking Florida. And in October 2007, Hurricane Felix took just over a day to go from a tropical storm to Category 5.
Including Erin, there have been 43 hurricanes that have reached Category 5 status on record in the Atlantic, said Dan Pydynowski, senior meteorologist at AccuWeather, a private forecasting company.
'They're certainly rare, although this would mark the fourth year in a row that we've had one in the Atlantic basin,' Pydynowski said. Conditions needed for hurricanes to reach such strength include very warm ocean water, little to no wind shear and being far from land, he said.
Scientists say warming climate linked to storms strengthening faster
Scientists have linked rapid intensification of hurricanes in the Atlantic to climate change. Global warming is causing the atmosphere to hold more water vapour and is spiking ocean temperatures, and warmer waters give hurricanes fuel to unleash more rain and strengthen more quickly.
Storms that ramp up so quickly complicate forecasting for meteorologists and make it harder for government agencies to plan for emergencies. Hurricane Erick, a Pacific storm that made landfall June 19 in Oaxaca, Mexico, also strengthened rapidly, doubling in intensity in less than a day.
Erin is the fifth named storm of the Atlantic hurricane season, which runs from June 1 to Nov. 30, and the first hurricane.
The 2025 season is expected to be unusually busy, with six to 10 hurricanes in the forecast including three to five reaching major status with winds of more than 110 mph (177 kph).
In San Juan, Puerto Rico, locals and tourists walked, exercised and shopped as usual Saturday. Restaurants were busy, and despite warnings to avoid beaches, people could be seen in the water at Ultimo Trolley and Ocean Park beaches. Parents kept their children from swimming, however.
Sarahí Torres and Joanna Cornejo, who were visiting from California for a Bad Bunny concert, said they decided to go to the beach and wade into the water because the skies appeared calm.
'The weather looked fine, so we came out,' Torres said.
The U.S. government deployed more than 200 employees from the Federal Emergency Management Agency and other agencies to Puerto Rico as a precaution. Puerto Rico Housing Secretary Ciary Pérez Peña said 367 shelters were inspected and ready to open if needed.
Meanwhile officials in the Bahamas prepared some public shelters as a precaution as they urged people to monitor 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.
