264STORM · DATA & SOURCES
Data sources & methodology
264Storm combines public official feeds, observational data and model guidance into one weather- and hazard-focused dashboard. It is not an official warning service. When an official authority and 264Storm differ, follow the official authority.
Weather, marine and air quality
Core island weather forecasts use MET Norway Locationforecast 2.0, normalized by 264Storm into a provider-neutral format. Outside the Nordic and Arctic regions, MET Norway uses the ECMWF global model. Aviation observations use public METAR data from AviationWeather.gov. Marine model and air/dust guidance remain separate feeds while free-source replacements are being integrated. When detailed marine model data are unavailable, 264Storm can use the official NHC OFFNT3 / AMZ051 Offshore Waters Leeward Islands sea-height forecast as a clearly labelled regional offshore fallback; it is not used to fabricate beach-level conditions.

Official weather authorities
Anguilla emergency guidance remains with DDM Anguilla. Sint Maarten weather guidance is linked to Meteorological Department St. Maarten. Saint-Martin and St. Barth use Météo-France and local authorities. Saba and Sint Eustatius are served by KNMI for the Caribbean Netherlands, including weather forecasts, marine information and warnings.

Storms and natural hazards
Atlantic storm information is derived from NOAA / National Hurricane Center products. Earthquake detections use USGS data. Caribbean tsunami messages use Pacific Tsunami Warning Center sources. Local emergency instructions remain with the relevant territorial authorities.
Alert hierarchy & regional relevance
For Anguilla, live operational DDM CAP alerts are the highest-priority authority and are shown verbatim. PTWC tsunami threat messages and NOAA/NHC tropical-cyclone products provide regional awareness, while 264Storm calculates an explicitly unofficial regional context layer. NHC systems elsewhere in the Atlantic basin are ingested for awareness but do not become 264Storm alerts unless their current or projected geometry creates a plausible northeastern-Caribbean impact pathway. If a required official feed cannot be confirmed, the interface fails closed rather than inventing an all-clear.

Beach outlooks
Beach condition guidance combines island-wide modelled wind, wave and swell data with approximate shoreline orientation and exposure. It is guidance only, not a lifeguard report or an official beach-safety rating.
Travel information now lives in the travel products
Regional flight schedules are maintained on 264Go. Ferry schedules and route guides are maintained on Anguilla Ferry Times. 264Storm now stays focused on weather, marine conditions and hazards.
