First of all, congratulations on 10 years with this blog, it's really amazing how far you've come as to what state the ENSO is currently at from month to month. Here's hoping that it will continue for years to come.

It's interesting to note that the Australian counterpart has declared that El Nino is over as of mid-April and are now on La Nina Watch as of mid-May. But it's also interesting to note that for seven weeks, a positive IOD was developing only for it to be stalled, although it could develop again albeit marginally on average.

I would like to know if La Nina does develop this year, how often does it occur with a positive IOD if that were to develop and how would this impact the summer, fall, and winter forecasts across North America if both events came to fruition? Usually La Nina often, although not always, is associated with a negative IOD, so this here would be quite unusual.
