NOAA Tides and Currents

Publisher-provided description

NOAA tides and currents: water levels, tide predictions, currents, met data, flooding, sun and moon

Summary by lookupd

Lets an agent query NOAA tide, current, water level and met data, plus NWS marine and wind forecasts and sun and moon times.
