The hemispheric long wave pattern has remained stable in recent weeks. There are four main troughs. Currently the most significant troughs are near the longitudes of the Indian Ocean, eastern Australia, the southeast Pacific, and the Atlantic Ocean.
Summary:
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 2024-03-18, 2024-03-23 and 2024-04-05. Rain events originating in the tropics and moving south are possible about 2024-03-18, 2024-03-23 and 2024-03-28. Over Western Australia the strongest cold fronts should occur about 2024-03-18 and 2024-03-23.
Forecast ExplanationThis forecast is produced by a multi-model ensemble consisting of dynamical atmospheric models, which are forced by the latest observed atmosphere, ocean, land and ice conditions. The models are designed to simulate features of the real atmosphere, including the daily movement of long and short wave patterns in the Southern Hemisphere.
The future probability of rain in each district is estimated using output from the multi-model ensemble, combined with historical information about the difference between the model forecasts and observed rainfall.
In this deterministic framework the skill of the forecast tends to decrease with time, however the forecasts are updated daily to provide the latest estimates of rainfall probability out to 28 days.

ENSO status: El Niño, breaking down. IOD status: Neutral. SAM status: Neutral, trending slightly positive. The El Niño Southern Oscillation (ENSO) is in an El Niño and is starting to break down. All international models indicate neutral conditions should return by late April or early May. The Southern Oscillation Index (SOI) is back below the threshold of -7, but is varying significantly with tropical activity over Australia and the Pacific. Waters in the Coral Sea are far warmer than normal, especially for an El Niño, and are offsetting the effects of this event. El Niño only has a small effect during autumn, typically increasing rainfall over the Nullarbor and SA, but having little effect elsewhere. The Indian Ocean Dipole (IOD) is in a neutral phase. Ocean temperatures are high across most of the Indian Ocean, with only cooler waters near the WA coast. The IOD has little to no effect during autumn. The Southern Annular Mode (SAM) is neutral and will slightly favour a positive phase during March and April and return closer to true neutral in May. A positive SAM increases easterly winds, increasing rainfall and thunderstorm activity in the east. As we go closer to winter, a positive SAM also reduces cold fronts and rainfall over southern Australia. Rainfall outlooks are predicting average rainfall for the vast majority of Australia throughout autumn. There are some weak signals that southwest WA could be slightly drier than normal in April, and southeast Qld and NSW could be slightly wetter during May, but otherwise near average.
