How to Use This Interactive Map
Island markers
Blue markers show the capitals of each eastern Caribbean island. Click one to view the latest observations — feels-like and actual temperatures, conditions, wind speed (with Beaufort descriptor), pressure, humidity and last update time.
When you click an island, three concentric rings appear showing approximate distances of 100, 200 and 300 miles100, 200 and 300 km. Use these along with the dashed forecast track to gauge storm proximity.
Closest approach (CPA)
Island pop-ups include a Closest approach line showing the minimum distance between the island and the storm's forecast track, with an approximate time. It does not imply landfall — values may change as the NHC updates its forecasts.
Scale & coordinates
The scale bar below the zoom buttons shows distances in km and miles. Moving your pointer over the map displays the cursor's latitude and longitude. Degree labels along the edges (every 5°) help align positions.
Wind radii
Amber circles show the radius of tropical-storm-force winds; red circles mark hurricane-force winds. These illustrate the maximum extent from the storm's centre. Forecast updates may adjust their size.
Weather overlay
Toggle this on to display the latest radar precipitation data from RainViewer. Colour intensity indicates rainfall rate, from light showers to heavy downpours. Radar coverage may be limited over open ocean areas far from land-based stations.
Update schedule
The map fits all islands and storms into view and is updated eight times daily (02:00, 05:00, 08:00, 11:00, 14:00, 17:00, 20:00 and 23:00 AST). Use alongside official forecasts from the NHC and your local meteorological service.
