Key Aspects:
- Tropical Storm Erin has officially formed and is on track to impact the Eastern Caribbean at the end of the week.
- There is great uncertainty several days out in the forecast, but all cruisers should watch the storm carefully.
- No cruise line has confirmed itinerary changes, but they will be monitoring the storm and will make any adjustments necessary to keep ships safe.
Hurricane season is heating up right on schedule, and that means cruisers need to be extra aware of how storm systems may impact their sailings.
On Monday morning, August 11, 2025, Tropical Storm Erin officially formed in the eastern Atlantic. While several days away, her path likely to bring the storm to the eastern Caribbean.
This may impact a number of popular ports of call, as well as cruise ships with itineraries heading east over the next 7-10 days.
The first official advisory for Tropical Storm Erin was issued by the National Hurricane Center (NHC) at 11 a.m. Eastern Time.
The storm has maximum sustained winds of 45 miles per hour, well above the 39 mph threshold for a tropical storm.
The westward track will bring Erin close to the top Eastern Caribbean ports on Friday and Saturday, August 15 and 16, before she turns north.
Forecast predictions have the storm likely to be a major hurricane of Category 3 or higher by that time.
Ports likely to at least feel moderate impact include Barbados, St. Lucia, the US and British Virgin Islands, and Puerto Rico.
Depending on when and how Erin turns north, the Turks and Caicos as well as the Bahamas, including private islands, are also likely to feel some impact.
Ships departing on Eastern or Southern Caribbean itineraries this coming weekend are most likely to have at least some itinerary changes.
This could include Rhapsody of the Seas from San Juan; Wonder of the Seas from Port Canaveral; Carnival Celebration from Miami; and Norwegian Aqua from Port Canaveral, among others.
To be clear, no cruise line has yet altered any sailings for Tropical Storm Erin. All cruise lines keep safety as the top priority and they will undoubtedly be monitoring the storm as she draws closer.
How Strong Will Erin Become?
The NHC’s forecast discussion advises caution this early, as it is always hard to predict how a tropical storm or hurricane will act several days in advance.
“The intensity forecast in the short-term is a little tricky,” the notes read. “The rate of intensification
will likely increase in the second half of the forecast period.”
Wind shear, ocean temperature, regional atmospheric conditions, and other factors will all interact to determine how the storm may intensify and how she will move.
Forecast tracks (the “spaghetti” plots) do show the storm likely to turn north long before impacting larger islands or the Florida peninsula. That turn will not likely happen until the weekend, however, and could be significantly different than predicted so early in the storm’s formation.

Some forecast models show Erin reaching as high as a devastating Category 4 or 5 storm, though most believe she will remain no more than a Category 2 or 3 intensity.
Just as her path is difficult to predict precisely so many days away, however, her intensity can also vary tremendously as she gets closer.
Furthermore, the overall size of Erin’s wind field will also determine how far away her impact may be felt. Very large storms can often impact ports of call or cruise homeports hundreds of miles from the storm’s eye.
The peak of hurricane season, when storms are strongest and most numerous, is typically around September 10. This does not mean that storms before or after this date are any less dangerous or disruptive.
Any cruise guests with sailings booked over the next few days should watch Tropical Storm Erin carefully. Likewise, anyone with Caribbean sailings booked at this time of year should always stay informed about potential storms in case their cruise is impacted.
