Minor Flood Warning For The Barcoo River
Issued at 10:26 AM EST on Monday 04 December 2023
Flood Warning Number: 6
RENEWED MINOR FLOODING POSSIBLE AT RETREAT ON THE LOWER BARCOO RIVER OVER THE WEEKEND
NO FURTHER FLOODING EXPECTED AT BLACKALL
No significant rainfall has been recorded across the Barcoo River catchment over the last few days. No significant rainfall is forecast for the next few days. Rainfall from last week caused river level rises along the upper Barcoo River in the Blackall area. These floodwaters are still travelling downstream.
Barcoo River to Isisford:
No further flooding is expected in the Barcoo River to Isisford.
River level observations are not available for the Barcoo River at Blackall (manual station) but based on the nearby automatic station, the river level is expected to have fallen below the minor flood level (2.00 m) late Friday evening, and is expected to continue falling.
The Barcoo River at Blackall is expected to remain below the minor flood level (2.00 m).
Barcoo River downstream of Isisford:
Minor flooding may occur along the Barcoo River downstream of Isisford.
The Barcoo River at Retreat is currently at 1.15 metres and steady, below the minor flood level (2.14 m).
The Barcoo River at Retreat is likely to remain below the minor flood level (2.14 m) for the next few days, with minor flooding possible over the weekend with the arrival of the floodwaters from upstream.
Flood Safety Advice:
Remember: If it's flooded, forget it. For flood emergency assistance contact the SES on 132 500. For life threatening emergencies, call Triple Zero (000) immediately.}

CHANCE OF RAINFALL WITHIN DISTRICTNIL < 25%LOW 25% to 50%MEDIUM 50% to 75%HIGH ≥ 75%Issued Dec 5Issue Notes
The hemispheric long wave pattern has been relatively fast moving in recent weeks. There are six main troughs. Currently the most significant troughs are near the longitudes of South Africa, the southwest Indian Ocean, the Indian Ocean, New Zealand, the south Pacific, and the southeast Pacific.
Summary:
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 2023-12-08, 2023-12-19 and 2024-01-01. Rain events originating in the tropics and moving south are possible about 2023-12-16, 2023-12-22 and 2024-01-01. Over Western Australia the strongest cold fronts should occur about 2023-12-06, 2023-12-11 and 2023-12-16.
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, reached a strong event. IOD status: Positive IOD, starting to weaken. SAM status: Neutral, trending positive. The El Niño Southern Oscillation (ENSO) is in an El Niño, with all international models indicating this event will continue until at least April 2024. Ocean warming is continuing to occur in the eastern and central Pacific and has reached the threshold for a 'strong event'. The Southern Oscillation Index (SOI) has reduced further and is comfortably below the El Niño threshold, especially over the last 90-days. El Niño only has a limited effect on rainfall during summer, drying Far North Qld, increasing rainfall over the Nullarbor, and having little effect elsewhere. El Niño also typically delays the first monsoon onset and reduces the number of tropical cyclones impacting Australia, but otherwise has little effect on Australia during January and February. The Indian Ocean Dipole (IOD) is in a positive phase but is weakening from its peak in late October. Winds areexpected to weaken with the current tropical activity, but generally SE wind near Jakarta should maintain the event The IOD typically takes 3-6 weeks to decay, so could persist into the start of 2024. However, the first monsoon onset over northern Australia will still sever its effect on Australia. A positive IOD greatly reduces the formation of northwest cloudbands, leading to reductions in spring rainfall over northern WA, central Aus, and the southeast. A positive IOD often has a compound effect with El Niño, reducing rainfall even further. The Southern Annular Mode (SAM) is currently neutral. It is expected to favour a positive event for the remainder of December. Longer-term, since negative SAM events become more likely during El Niño, models suggest it becoming strongly negative around February. A negative phase tends to increase cold front activity over southern Australia, increasing rainfall over southern Vic, western Tas, and southeast SA, while decreasing it for eastern NSW and Qld. The opposite occurs in a positive event, with easterly winds more likely, increasing rainfall and thunderstorm activity in the east, but reducing it in southern and Western Australia. Rainfall outlooks are predicting above average rainfall for eastern NSW & Qld, below average rainfall over the Tas and far northern Australia, and average elsewhere in December. Large rainfall deficits are expected over northern Australia from December, likely with a delayed initial monsoon onset. Rainfall is forecast to be above average in the NT and NSW during January, with average to slightly below average elsewhere, with drier than normal conditions forecast throughout in February.
