NOAA forecasts record-shattering El Niño intensity

The National Oceanic and Atmospheric Administration (NOAA) has updated its forecast, stating there is a nearly 70% chance that the current El Niño event will become the strongest on record. This update follows rapid intensification and computer model guidance suggesting the event will peak in late fall and early winter at a higher level than previously anticipated.

If the trend continues, this event could surpass the massive Super El Niño of 1982–1983. Forecasters expect sea surface temperature anomalies in the Niño region to exceed 2.5 degrees Celsius above average. To account for rising background ocean temperatures caused by long-term climate change, NOAA is utilizing the Relative Oceanic Niño Index (RONI).

El Niño cycles involve warmer than average ocean temperatures in the central and eastern tropical Pacific, which can shift global weather patterns. Potential impacts include droughts in Indonesia and Australia, as well as flooding in parts of South America.
