The latest La Nina advisory was released today by NOAA’s Climate Prediction Center. It shows that a strong La Nina signal is in place in the eastern Pacific Ocean and that the winds are now in sync with the ocean conditions. This means that La Nina is likely to continue through the winter months and into next spring. You can read more at https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.shtml. The consensus of models is that this event is likely to remain relatively weak, which means the strongest effects are likely to be limited to Florida and southern Georgia and Alabama. That would include warmer and sunnier than normal conditions as well as drier than normal precipitation. La Nina is not linked to late frosts but if it returns to neutral conditions earlier in 2021, late spring frosts are more likely in neutral years. We also know that summers after a La Nina are more likely to experience drought because of the lack of soil moisture recharge over the cool winter months.
