Incredibly warm waters continue to build across the equatorial Pacific, and the El Niño event of 2015 has just set a record for the warmest waters ever observed in the equatorial Pacific over a 1-week period...The weekly departure of SST from average in this region hit +3.0°C (5.4°F) over the past week...This exceeds the previous 1-week record warmth in the equatorial Pacific of 2.8°C above average set during the week of November 26, 1997...However, the standard measure for the strength of an El Niño event is the three-month average Niño 3.4 SSTs...[I]t is likely that one of the late-year three-month average Niño 3.4 SST values in 2015 will end up upending 1997's record warmth
