This is the first time this hurricane season where we've seen a subtropical storm. For those wondering what that means, here is the NHC definition:
- Subtropical Cyclone:
- A non-frontal low pressure system that has characteristics of both tropical and extratropical cyclones. This system is typically an upper-level cold low with circulation extending to the surface layer and maximum sustained winds generally occurring at a radius of about 100 miles or more from the center. In comparison to tropical cyclones, such systems have a relatively broad zone of maximum winds that is located farther from the center, and typically have a less symmetric wind field and distribution of convection.
Cruise Line Advisories
Norwegian Sun is swapping its planned northern route crossing of the Atlantic Ocean for a more southerly one to avoid 35 knot winds and 24 foot swells kicked up by Hurricane Otto. The new route will force it to skip its call in Punta Delgada, Azores, on Saturday. The ship will arrive on schedule in Orlando on October 16.
Carnival Liberty skipped its call in Grand Turk yesterday. Instead of a sea day today, the ship will add a call in Nassau. It returns to Miami as planned on Saturday.
Due to the storm, Celebrity Solstice is unable to dock in St. Maarten on Thursday.
Instead, the ship will spend tomorrow at sea and will add a call in Montego Bay, Jamaica, on Friday before returning to Fort Lauderdale as scheduled on Sunday.
