Updated El Niño Forecast Models Get Even Stronger

Updated Niño Models Get Even Stronger

 

The updated forecast models for El Niño Sea Surface Temperature Anomalies (SSTA) from IRI/CPC have gotten even stronger.  Last month's average of the 17 dynamic models had the Oceanic Niño Index (ONI) peaking at 2.2 in the October/November/December (OND) period and now they are forecast to peak at 2.5 in OND and stay there through NDJ. If these numbers verify, then we are looking at SSTA's that rival 1997-98 and 1982-83.

Even with all the usual caveats about no guarantees, this trend is very encouraging for a continuing increase in the chances of above normal precipitation in California. Additional El Niño related links can be found at the El Niño / La Niña Resource Page.  Stay Tuned.
