The Nino34 SSTA region in the east-central equatorial Pacific Ocean shifted warmer last week to +1.00 as El Nino steadily strengthens and approaches moderate intensity. Waters off the northwest coast of South America (Nino12 region) are the warmest since May 1998 which along with 1982 and 2015 marked the strongest El Nino on record.
