Forecasters have announced a high probability of a very strong El Niño event developing in the Pacific Ocean, which could bring significantly wetter conditions to Southern California this winter. - There is a 63% chance of a very strong El Niño during November-January, ranking among the largest since 1950.
- Typical impacts include increased rain and snow in the southern U.S., and higher flood risk during high tides on the West Coast. - The jet stream is expected to shift southward, causing drier conditions in some northern regions but stormier weather in the south.
- NWS officials emphasize that each El Niño is unique, but advanced monitoring helps improve forecasts and public preparedness.
