SATELLITE OBSERVED WAVES (ERS-2) and MODELED IMAGERY
00hr Atlantic Ocean Sea Height and Period (NOAA OMB) This is a good source to view sea heights within a storm and to observe approaching swell fronts. Seas heights and period/swell fronts are modeled (not confirmed via ERS-2 satellite) using the Wavewatch III Wave Model driven by the AVN atmopsheric model. (Note: Heights are in meters. Multiply readings times 3.28084 to convert to feet. Data updated 2 times daily).
