La Niña ... Not Fading Away

The current La NIña in the eastern tropical Pacific remains stubbornly in place, with ONI essentially flat-lined on the border between "weak" and "moderate" categories. (https://ggweather.com/enso/oni.htm)



Since at least the first of the year, forecast models have shown warming into "neutral" territory, but to date, reality has not cooperated. (https://iri.columbia.edu/our-expertise/climate/forecasts/enso/current/?enso_tab=enso-sst_table)



And significant upwelling of cool water in the ONI 3.4 region, points toward little change in the short term. (http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_update/wkxzteq.shtml)


One of the impacts of the ONI remaining in negative territory will be the potential for a more active than average hurricane season in the Atlantic Basin. This is reflected in the Seasonal Hurricane Forecast issued by Colorado State University earlier this morning. (https://tropical.colostate.edu/forecasting.html)
