70% chance of 'strong' El Niño: How long will it last?

(NEXSTAR) – This year's El Niño season is looking stronger and longer in the latest outlook released by the National Oceanic and Atmospheric Administration.
The odds of a historically strong El Niño grew to 71% in this month's update.
Even more certain is the climate pattern seems determined to stick around. NOAA forecasters said there's a larger than 95% chance it last until the start of spring and a 60% chance it keeps going all the way until summer.KRQE meteorologist
