It was a weekend of meteorological drama as Hurricane Erin, the fifth named storm of the Atlantic season, showed its full force.
Once a Category 5 monster with 160 mph winds, the storm weakened briefly, only to power back to Category 4 strength late on Sunday.
But as Puerto Ricans looked skyward, the question was inevitable: how close will Erin really get, and what does that mean for those in its path?
A Storm That Refuses to Settle
According to the National Hurricane Center (NHC), Erin completed an eyewall replacement cycle on Sunday evening, a process that often causes temporary weakening before a storm restrengthens. That prediction proved correct.
Within hours, Erin was again hurling sustained winds of 130 mph as it tracked northwest at 12 mph.
The NHC warned that 'some additional strengthening is expected over the next 12 hours followed by gradual weakening,' though Erin is also forecast to grow in size.
This means that, even if its peak power fades, the storm could still bring dangerous conditions to a wider area across the Atlantic basin.
Puerto Rico on High Alert
While the centre of Erin's eye is expected to skirt north of Puerto Rico and the U.S. Virgin Islands, meteorologists caution that the impacts will still be felt.
AccuWeather reports estimate rainfall totals of 1–2 inches across much of northern Puerto Rico, with isolated pockets receiving as much as 7 inches.
Wind gusts are another concern. Forecasts suggest gusts of 40–60 mph could sweep across the island, with isolated surges approaching 80 mph in exposed coastal regions.
The combination of heavy rain and high winds could lead to flash flooding, fallen trees, and power outages. 'Even without a direct landfall, Erin is close enough to rattle nerves and stretch local infrastructure,' one analyst told The Independent.
Dangerous Seas and Wider Travel Chaos
Erin's reach extends far beyond Puerto Rico. The hurricane is already producing pounding surf and rip currents across the Leeward Islands, and forecasters expect rough seas to spread up along the U.S. East Coast later this week.
Beachgoers and shipping lanes alike have been warned to exercise extreme caution.
Meanwhile, the storm's timing could hardly be worse for transport. With transatlantic flights rerouted and cruise itineraries altered, Erin is causing ripple effects in travel.
Meteorologists say this is typical of large systems: 'The bigger they grow, the more they disrupt – even when they don't hit directly,' as one BBC Weather presenter noted.
The Bigger Picture of 2025's Hurricane Season
Erin is the fifth named system of the 2025 Atlantic season, following Andrea, Barry, Chantal, and Dexter. Chantal alone brought devastating floods to parts of North Carolina in July.
Now, Erin has already etched its name into the record books as both the first major hurricane of the year and a rare Category 5 storm.
Experts point to unusually warm waters and favourable atmospheric conditions as the key drivers of Erin's rapid intensification.
AccuWeather's lead hurricane specialist Alex DaSilva explained: 'Atmospheric and oceanic conditions northeast of the Lesser Antilles led to Erin's rapid strengthening.'
With the season far from over, such conditions raise concerns about what lies ahead.
Conclusion
So, is Puerto Rico at risk? The latest 7-day projections suggest the island will avoid a direct hit, but the impacts are already being felt – from heavy rainfall and powerful gusts to dangerous coastal surf.
Erin is a reminder that, in the tropics, storms need not strike head-on to leave a mark. As the hurricane continues its north-westerly climb, millions will be watching, waiting, and hoping that this mighty system steers further out to sea.
