What this feed is
CurrentStorms.json from the National Hurricane Center, plus a flag for whether a storm meets the Caribbean box used here. An empty list is valid. It is not a local forecast for one island.
Where it applies
NHC's active list, which can include storms outside the Caribbean. The Caribbean flag is computed on that list. Hourly in June–November, every six hours otherwise.
Who it is for
Duty desks and agents that need a machine-readable storm list under a US government public-domain licence. Start with the unauthenticated sample.
