Final Flood Warning For The Greenough River Catchment
Issued at 10:24 AM WST on Sunday 07 March 2021
Flood Watch Number: 4
FLOODING IS EASING IN THE GREENOUGH RIVER
Heavy rainfall in the upper catchment of the Greenough River has caused stream level rises, areas of flooding and adverse road conditions as flood waters travelled downstream. No further rainfall expected and flooding impacts will gradually ease in the coming days. While flooding subsides roads may still be impacted for some time.
In the 24 hours to 9:00 am Sunday, no significant rainfall has been recorded in the Greenough River catchment.
No significant rainfall is forecast for the remainder of Sunday and into Monday.
Greenough River:
Flooding is expected to ease in the Greenough River. However areas of flooding may continue to adversely affect road conditions. Check road conditions before travelling.
The Greenough River at Karlanew Peak is currently at 2.72 metres and falling.
The Greenough River at Karlanew Peak is likely to fall below the minor flood level (2.50 m) Sunday afternoon.
Flood Safety Advice:
DFES advises people and communities to be aware that flooding is possible and be prepared to relocate equipment and livestock. Watch water levels. Travellers need to be aware that road conditions may be adversely affected and travel plans may need to be reconsidered. Do not drive into water of unknown depth and velocity.}
Community information is available from DFES at www.dfes.wa.gov.au

The hemispheric long wave pattern has remained stable in recent weeks. There are five main troughs. Currently the most significant troughs are near the longitudes of South Africa, the Indian Ocean, eastern Australia, the south Pacific, 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 13 March to 17 March, 22 March to 26 March, and 10 April to 14 April. Rain events originating in the tropics and moving south are possible about 17 March to 21 March, and 22 March to 26 March. Over Western Australia the strongest cold fronts should occur about 13 March to 17 March, 21 March to 25 March, and 10 April to 14 April.
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: La Niña IOD status: Neutral SAM status: Positive La Niña is likely at its peak which has brought long periods of cloud and rain to eastern and northern Australia.The majority of models predict that La Niña will continue through February, with 3 of 8 predicting to March and most of the models indicating a return to neutral conditions (neither El Niño nor La Niña) in April. Neutral conditions are predicted to continue into the Australian winter. La Nina typically brings above normal rainfall across much of Australia. While La Niña is expected to weaken, above normal rainfall and typical La Niña impacts are still expected. La Niña typically favours periods of positive SAM, which can increase the amount of precipitation along the eastern half of the country, due to prevailing onshore winds. During summer, much of the country is likely to remain wetter than normal, however normal rainfall is expected for western TAS. La Niña typically increases the number of cyclones and brought anearly start to the wet season. During Autumn, many parts of Australia are likely to be wetter than normal, due to warmer waters off the northeast coast of Australia. Southern parts of SA, VIC and most of TAS are likely to observe normal precipitation for the time of year.
