Are Hurricane Polo or Tropical Storm Fay a threat to Puerto Rico?
No, not based on today's reporting. Hurricane Polo is drifting off western Mexico, and forecasters expect it to stay at or near Category 5 strength for several more days. Primera Hora puts its winds around 160 mph. That is a Pacific coast problem on the far side of Mexico.
Fay has become a tropical storm again, and the National Hurricane Center is also watching an area near the coast of Africa for development, Primera Hora reports. Neither system is described anywhere as a threat to Puerto Rico.
So there is nothing to cancel this week. The calendar is the part worth your attention.
Why late September is still the month that decides your trip
Atlantic hurricane season officially runs June 1 to Nov 30. The statistical peak falls in the first half of September, and elevated risk runs to about mid-October. Today is Sept 24, so you are at the back end of the busiest stretch, not safely past it.
Wind is rarely what spoils a trip here. Rain is. A slow tropical wave passing north of the island can soak three days straight, and that changes what you can actually do. River-fed trails in El Yunque are usually the first to close when rainfall picks up. The bioluminescent bays need calm, dark water, so operators normally cancel tours for a few nights after heavy rain, not because of the storm itself but because there is no glow to see in churned water.
If your trip is Old San Juan, museums and food, rain costs you an afternoon. If it is beaches, Vieques or Culebra, it can cost you the whole point of the trip.
How to track a storm before you fly
Bookmark the National Hurricane Center and check it once a day, not every hour. The five-day forecast cone is wide on purpose, and it wobbles.
The thing that should trigger action is not the cone. It is a watch or warning for Puerto Rico. That is when US carriers usually publish a travel waiver for San Juan. It typically allows free date changes inside a set window, and the good rebooking options go first. Watch your airline's app at that moment.
Two habits help in September. Fly in the morning, since storms build over the island in the afternoon and a morning departure gives you a cushion. And keep everything in one airline's app so you are rebooked automatically instead of standing in a counter queue.
What to do if a storm forms while you are on the island
Puerto Rico's power grid is stronger than it was a few years ago, and most large hotels run on generators, but outages still happen. Fill water containers, charge power banks, and take out cash before the weather turns, because card readers and ATMs go down with the power.
Ask reception about extending your stay the day before landfall, not the morning after. Rooms disappear once flights are cancelled.
Ferry crossings to Vieques and Culebra are usually the first service suspended when a system approaches and among the last to restart. If you are booked on one of those islands ahead of a storm, decide early whether to leave or to settle in with supplies.
The riskiest hours are often the sunny ones before the storm. Swells reach the coast a day or two ahead of the weather, and the rip currents that come with them are the real danger. North coast beaches, including those around San Juan, get closed by lifeguards in those conditions. Treat a red flag as final.
Book early for the dates everyone else wants
Two items on Puerto Rico's calendar are already pulling demand.
Dominican singer Dalvin La Melodía sold out his first Coliseo de Puerto Rico show in about an hour, and a second date was added for Friday, Jan 15, 2027, El Nuevo Dia reports. The Coliseo is in San Juan, so that weekend will tighten hotel availability in San Juan and Isla Verde. Book a flexible room now and sort the flight after.
Separately, WJournalpr reports that the Puerto Rico Tourism Company has delivered documents tied to its Miss Universe 2026 agreement. Agreements of that size normally mean a run on metro-area rooms once dates firm up. If you are planning around either date, book the hotel before the flight. Room inventory is tighter than seat inventory.
One last thing before you book
Buy travel insurance when you book, not a week before you fly. Most policies stop covering a named storm once it has been named, so coverage bought after the fact usually does nothing for you. Read the trip interruption clause, not just the headline. A policy that gets you home when the airport closes is worth more than one that only pays out if the property is damaged.
And if you are traveling in the next three weeks with plans that can stay flexible, keep them flexible. A refundable rate costs more upfront and less when a system turns north.
