The 30-day SOI remains positive and indicating a La Nina, with the 90-day average firming. The latest daily air pressure values suggest the SOI shift is more related to higher pressure over Tahiti rather than Darwin. We would prefer to see the Darwin hPA contribution drop some more to encourage more moisture flow over inland Australia.

The good news is, broad-scale patterns are favouring a shift towards more moisture coming our way.
