According to a new forecast from the National Weather Service’s Climate Prediction Center, it’s likely that the La Niña weather pattern will show up this winter. The likelihood that it will show up this winter is the same as last month: a 55 to 60 percent probability. That’s a downgrade from June, when it was 75 percent. While El Niño is associated with warmer waters in the equatorial Pacific and warm, wet winters in Southern California, La Niña can be tied to cooling waters, and is better known for keeping things drier in the southern part of the state.
