Too little, too late?
CPC has upgraded their El Nino Watch to an El Nino Advisory <http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.html>, but with only a 50-60% chance it will persist through summer. The upgrade is despite the ONI dipping from +0.7 to +0.6. <http://ggweather.com/enso/oni.htm> and during a time of year when the influences of El Nino are waning.
An excellent analysis of these potential impacts can be found at http://www.climate.gov/news-features/blogs/enso/march-2015-enso-discussion-el-ni%C3%B1o-here.
