Capricornia 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 the Indian Ocean, eastern Australia, the south Pacific, the southeast Pacific, South America, and the Atlantic Ocean.
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 16 May to 20 May, 22 May to 26 May, and 31 May to 4 June. Rain events originating in the tropics and moving south are possible about 8 May to 12 May, and 16 May to 20 May.
Over Western Australia the strongest cold fronts should occur about 16 May to 20 May, 22 May to 26 May, and 31 May to 4 June.
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.
High winds with gusts of up to 100 kilometres per hour are hitting Melbourne and parts of southern Victoria as part of a deep cold front moving across the state.
The weather bureau is warning Tasmanians of a wet and windy week ahead, after gusts associated with a cold front caused widespread power outages overnight.
