Inconclusive indicies related to those periods, not really what I would expect. Could be obscured in the period by a short period of chance on the indicies, which is not reflected in February's average. I also wonder how rare it is to get +PNA, -NAO, -AO in a la Nina year. We probably don't have a very good analog pattern.
2009 AO -, PNA -, NAO neutral
1996 AO neutral , PNA -, NAO neutral
1989 AO +, PNA -, NAO positive
