"The strongest El Niño in 18 years continues to intensify and is likely to be one of the three strongest on record by the time it peaks this winter, according to a monthly outlook from NOAA released Thursday morning.
This El Niño is then expected to weaken in the spring, disappearing altogether by late spring or early summer 2016, the November El Niño diagnostic discussion from NOAA's Climate Prediction Center said.
El Niño is an anomalous, yet periodic, warming of the central and eastern equatorial Pacific Ocean. For reasons still not well understood, every two to seven years, this patch of ocean warms for six to 18 months.
This warming of equatorial Pacific water influences the atmospheric pattern from the western Pacific Ocean, including Australia and Indonesia, to North and South America, the Atlantic Ocean, even parts of Europe and Africa.
Precipitation and temperature impacts in the U.S. from a strong El Niño are typically most noticeable during the colder months, from late fall through winter. We have more on what those impacts are later in this article."
