The Japan Agency for Marine-Earth Science and Technology, or JAMSTEC, is a Japanese national research institute for marine-earth science and technology

From the JAMSTEC Discussion:

Observation shows that the La Niña decayed and a La Niña Modoki-like state has appeared. The SINTEX-F ensemble mean predicts that an El Niño will occur in May. However, there is a large uncertainty in the predictions of the amplitude, and the ensemble mean of the SINTEX-F2-3DVAR version predicts a relatively weak El Niño.

Although it is a World forecast, it includes a forecast for North America since North America is part of the World.
