Using this map
This map shows the capitals of each eastern Caribbean island as blue markers and any active storms as red hurricane icons. Click on a blue marker to view the latest observations for that island — including feels‑like and actual temperatures, current conditions, wind speed (with Beaufort descriptor), pressure, humidity and last update time.
When you click an island, three concentric rings appear centred on its capital. These illustrate approximate distances of 100, 200 and 300 miles100, 200 and 300 kilometres. They update automatically when you switch between metric and imperial units. Use these rings along with the dashed forecast track to gauge how close an active storm could come to a particular island.
Island pop‑ups also include a Closest approach line. This shows the minimum distance between the island and the storm’s forecast track during the current forecast period, together with an approximate time until (or since) that point. It does not imply landfall — it simply tells you how near the storm’s track is expected to get. These values may change as the National Hurricane Center updates its forecasts.
The scale bar sits just below the +/– zoom buttons and shows distances in both kilometres and miles. When you move your pointer over the map, a small readout beneath the scale displays the cursor’s latitude and longitude (e.g. 16.3°N, 43.4°W). Degree labels along the top and right edges (every 5°) help you align positions.
The map automatically 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). It is intended to provide quick, at‑a‑glance context and should be used alongside official forecasts and warnings from the National Hurricane Center and your local meteorological service.
Amber circles show the radius of tropical‑storm‑force winds, while red circles mark the radius of hurricane‑force winds. These circles illustrate the maximum extent of those winds from the storm’s centre. Use them to gauge whether storm‑force winds could reach nearby islands, and remember that forecast updates may adjust their size.
