Active Tropical Storms and Hurricanes Right Now (National Hurricane Center)

nhc/active-storms

Every tropical or subtropical cyclone the National Hurricane Center is currently tracking in the Atlantic, Eastern Pacific and Central Pacific: storm id, name, classification (TD, TS, HU and so on), maximum sustained wind in knots, minimum pressure in millibars, position as text and as signed decimal degrees, movement direction in degrees and speed in miles per hour (mph, not knots), the time of the last update, and links to the latest public advisory, forecast advisory, wind speed probabilities, forecast discussion, track and cone products. Takes no input. An empty list means no storm is being tracked right now. NWS National Hurricane Center data, served by Eden Engine; not an official NWS or NHC product.
