MAJOR FLOODING LIKELY AT LONGREACH FROM LATE TUESDAY MORNING AND POSSIBLE AT STONEHENGE FROM WEDNESDAY EVENING
MAJOR FLOODING POSSIBLE FROM TUESDAY MORNING AT ISISFORD
MODERATE FLOODING OCCURRING AT CAMOOLA PARK AND STONEHENGE
Heavy to intense rainfall during the last week caused rapid rises and significant major flooding across the Thomson, Barcoo and Cooper Creek catchments. Major flooding is occurring at Jundah, Retreat, and Windorah.
At Jundah, the river level peaked above both the 1974 and 1955 flood levels. At Retreat, the river level is estimated to have peaked overnight Friday with major flooding, higher than the April 1990 flood level. As these floodwaters combine along the Cooper Creek, it is estimated that a major flood peak near the January 1974 flood level may have occurred at Windorah Saturday afternoon.
Major flooding easing slowly at Jundah, Retreat and Windorah. Moderate flooding is occurring at Camoola Park and at Stonehenge. Minor flooding is occurring at the Thomson River at Longreach, and expected to reach the moderate flood level early Monday evening. Further river level rises to major is likely from late Tuesday morning.
Moderate flooding is likely at the Barcoo River at Isisford from early Monday evening, and further river level rises to major is possible from Tuesday morning.
Further rainfall is forecast across the catchment during the middle of the week which may result in small renewed river and creek level rises and prolong the current flooding.

ENSO status: Weak La Niña-like conditions. IOD status: Neutral. SAM status: Neutral. The El Niño Southern Oscillation (ENSO) is in a weak La Niña-like pattern. The US declared a La Niña event this summer, but this event has not met the BoM definition, and will likely end in the coming weeks. A La Niña typically increases rainfall over northern and eastern Australia, while reducing rainfall over southern coastal Australia and western Tas. The Indian Ocean Dipole (IOD) is in a neutral phase and does not play a part in Australia's climate during this time of year. The Southern Annular Mode (SAM) is in a neutral phase. Forecasts show a tendency towards the positive phase in autumn, with the long-wave pattern indicating that cold fronts are a bit less likely for Australia's longitudes over the next few months. During autumn, a positive SAM increases rainfall over most of eastern Australia, and decreases rainfall for SA, Vic and western Tas. Rainfall outlooks are showing above average rainfall across much of northern Australia in April due to lingering monsoon activity. Above average rainfall is expected for the NSW coast through autumn, with wetter conditions also developing over western WA from late autumn. SA, Vic and Tas are expected to be average to slightly below average, with average conditions elsewhere.
