Last fall or early winter [2017], I saw an online article describing a situation that was setting up in the Western Pacific.
It had a small map that showed an area that would have a wetter winter season.
That strip ran across the Pacific just north of the Equator and looked to include Hawaii at its Eastern end.
If memory serves me, it was described as not being an El Niņo or La Niņa event, and was called something else.
I cannot find anything now that gives that description.
Does anyone know what it was called?
