Final answer:
El Niño typically leads to a warm winter in the northeastern U.S.
Step-by-step explanation:
The impact of El Niño on the northeastern U.S. is typically a warm winter. El Niño is a climate pattern that occurs irregularly and is characterized by warmer than normal sea surface temperatures in the equatorial Pacific Ocean. This can result in a shift in the jet stream, causing warmer air to move towards the northeastern U.S. during the winter months.
