A negative Indian Ocean Dipole is expected to bring above average winter and spring rainfall to parts of southern Australia, while warmer ocean temperatures to the north and northwest of Australia is likely to increase moisture available to be drawn into rain systems crossing the country. Streamflows are expected to be near median or high across the country, while days are likely warmer than average in the north and parts of the south, night temperatures are expected to be warmer across the country.
