That is a cool feature (multiple wave patterns). NOAA forecasts normally only include wind
waves and primary swell, which is useful, but having forecasts/observations for multiple wave patterns could help develop a mental image of what to expect.
Reminds me of a trip in rough weather
from E Carib to E coast USA. We had wave patterns from 2 differents lows. One was nearby and was the primary pattern we encountered (swell + wind
wave). The other was further off but stronger and generating bigger swells nearly perpindicular to the primary swell. And...it was very overcast and pitch
black out...we could not actually see the larger secondary swell, but periodically one would break and you could hear it rumbling in from starboard...hard to starboard...crash thru wave...hard to port and back on course...it became routine...bit of a disturbing routine in retrospect...no idea how big the breaking waves were, but big enough to cause a steep climb and lots of water
