As robust storms continue to move through California, El Nino conditions in the Pacific Ocean are already starting to weaken, a National Weather Service expert says.

 

Sea surface temperatures in the equatorial Pacific that serve as a key fuel for the weather phenomenon are starting to cool, although a strong El Nino is expected to persist in the Northern Hemisphere through the winter, said Michelle Mead, a National Weather Service warning coordinator.

 

The current weather pattern, fed by a dominant subtropical southern jet stream, is typical for a strong El Nino winter, Mead said in an email.
