Erin rapidly intensifies to category five hurricane
Hurricane Erin has explosively intensified into a Category 5 hurricane, now packing maximum sustained winds of 160 mph (260 km/h), according to the National Hurricane Center (NHC).
At a briefing, NHC Director Mike Brennan described the storm as “extremely powerful,” noting that it underwent rapid intensification—a process where wind speeds increase by at least 34 mph within 24 hours. Erin strengthened dramatically overnight, growing from tropical storm status on Friday to a Category 5 hurricane by early Saturday.
The storm is forecast to pass north of the Leeward Islands, the Virgin Islands, and Puerto Rico over the weekend. It is expected to bring up to 6 inches (15 cm) of rain to the region, raising the risk of flash flooding and mudslides.
Despite its strength, Erin is not currently projected to make landfall on the U.S. mainland.
By next week, the hurricane is expected to move gradually northward, passing east of the Bahamas and approaching the Outer Banks of North Carolina. The storm will generate dangerous surf and rip currents along nearly the entire U.S. East Coast, with Florida and the mid-Atlantic states likely to experience the most hazardous conditions. Bermuda is also expected to face life-threatening waves and heavy rainfall.
In preparation, the U.S. Coast Guard has implemented vessel restrictions at ports in St. Thomas and St. John in the U.S. Virgin Islands, as well as six municipalities in Puerto Rico, including San Juan, due to gale-force winds.
The National Oceanic and Atmospheric Administration (NOAA) has forecast an “above-normal” hurricane season for the Atlantic in 2025. Experts warn that the number of intense storms—particularly Category 4 and 5 hurricanes—is expected to rise as a result of global warming.
