The weather phenomenon known as El Nino is fading, and drought conditions remain entrenched in San Diego and the rest of California, according to a pair of reports released Thursday.

The Climate Prediction Center, part of the National Weather Service, announced a 75 percent chance that a La Nina pattern could form in El Nino’s place. El Nino is characterized by warmer than usual ocean water temperatures in the equatorial Pacific and often brings more rain than normal to the state.
