Although I have not directly observed the intensity of the instability waves week to week, I expect them to gradually become less intense as we go forward, because they are strongest when the temperature difference between the cold water right along the equator and the surrounding water is greatest. The time when this temperature difference was greatest was most likely a couple of months ago, when the warm waters from the El Nino were still hanging around but the much colder waters right at the equator appeared. Since then there has been more mixing of the two contrasting temperatures (which the waves facilitate) and the area of the cold water somewhat widened away from the immediate equator, and the warmth of the surrounding waters weakened.
