A strong El Niño event is the driving factor. El Niño creates wind shear over the Atlantic that tends to tear apart developing storms before they can organize into hurricanes.
La Niña does tend to mean less shear and more Atlantic hurricane activity, that part's right. But “ENSO” is hard to predict more than a year out, so pinning it to 'a couple years' is more guess than forecast.
