Thanks for the heads-up Clive,
The Australian BOM will have an ESNO update tomorrow, 14 Sept 2011, so
it will be interesting to see if the trend continues.

The BOM web site suggests "It’s worth noting that since 1900, about half of all
La Niņa events re-emerged in the second year".
Many will undoubtedly be hoping that any return this year will be weak.
Many more will be hoping that it is well and truly gone come Cairns November 2012.
