Ocean SFX on Panjura During Heavy Storms

I logged in to a heavy storm on Panjura, and I could hear the SFX you'd hear on Gondwa or Riparia near the ocean (waves crashing on the shore). This SFX shouldn't be present on Panjura, because there are no oceans. I was near water, kind of, but I've never heard this sfx trigger for lakes/ponds on Panjura at all until now. And even when I walked away from the lake, it was still present and JUST as loud. Therefore I think this an audio bug and not intentional.

Logged onto my deinocheirus in the lake at Redwood Basin during a heavy storm. I noticed the familiar sound of the ocean shore that I've heard on Gondwa (mostly) and Riparia. I thought it might have been a new thing since I was near the lake, but when I strayed from the lake, it was still just as loud and coming from nowhere/random angles. The noise stopped as soon as the storm went from a heavy storm to a normal rainstorm.

Ocean shore sfx shouldn't be present on Panjura because there is no ocean. And if it was a new feature for large bodies of water, why was it still present when I moved away from the large body of water?
