It will keep strengthening on the surface probabably.
There has never been a -PNA October during La Nina! The greatest was +120dm in 2007 and 2008, we had the strongest two, but I think both had a stronger EPO. Since satilte data in 1948- 1955, 1975, 1985, 6 years were strong +PNA/La Nina. Last year, 2020 was +PNA/La Nina.
Models through mid-October have about a +200dm -PNA, and we have never really done that before for the month of October in La nina since 1948. It will be interesting to see if we beat the 2007/8 record of +120dm for themonth. (last year was +PNA October-LaNina)
