Lower Eyre Peninsula 28-day Rainfall Forecast
|Chance of rainfall within district|
25% to 50%
50% to 75%
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, eastern Australia, the south Pacific, the southeast Pacific, and South America.
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 10 March to 14 March, 19 March to 23 March, and 26 March to 30 March. Rain events originating in the tropics and moving south are possible about 2 March to 6 March.
Over Western Australia the strongest cold fronts should occur about 4 March to 8 March, 12 March to 16 March, and 19 March to 23 March.
This 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.
Flood-affected farmers in the Ravensthorpe shire on the south coast of WA say the State Government has been slow in reacting to their plight, adding there is a lack of comprehension around the scale of the damage.
The seasonal outlook for autumn is hot and dry, but what is causing it? Both maximum and minimum temperatures look to be above average, especially for central Australia, extending down through inland NSW and western VIC.
Wrapping up a hot and humid summer many will be happy to forget, rain is on its way for most of NSW east of the divide.
