October 8 Update on La Nina

As of October 8th, the current La Nina is central-based, meaning the coolest temperatures are in the middle of the ENSO monitoring regions. Below is an image of where the ENSO Monitoring regions are.
Putting that together with the current SST (Sea Surface Temperature) Anomalies leads to the conclusion of a central based La Nina with maybe some western-based support. What does this mean right now? Little, if anything. The Nina will continue to change as we work our way into winter. What does this mean for our winter forecast? Nothing- there may have to be some adjustments on the final forecast in Mid-November, but right now we do not feel anything needs to be changed.
