Rainfall this week

During the week ending 18 April 2018 rainfall was mainly restricted to eastern Australia and isolated parts of southern and northern Australia. Little to no rainfall was recorded across the remainder of the country.

Rainfall totals between 25 and 50 millimetres were recorded in south-eastern South Australia, southern Victoria, and isolated parts of north-eastern New South Wales. Similar totals were recorded in coastal parts of northern Queensland and isolated areas of the Kimberley and adjacent parts of the Top End. Higher totals (between 50 and 100 millimetres) were recorded in alpine regions of Victoria and New South Wales, and western Tasmania. The highest recorded weekly total was 285 millimetres at Euramo, south of Innisfail in northern Queensland.

Note: The rainfall analyses and associated maps utilise data contained in the Bureau of Meteorology climate database, the Australian Data Archive for Meteorology (ADAM). The analyses are initially produced automatically from real-time data with limited quality control. They are intended to provide a general overview of rainfall across Australia as quickly as possible after the observations are received. For further information go to Weekly Rainfall Update.

Temperature anomalies this week

For the week ending 17 April 2018, maximum temperatures were between 2°C to 4°C above average across most of mainland Australia. Higher maximum temperatures (4°C to 6°C above average) were recorded across most of New South Wales, parts of south-western Queensland, western parts of the Northern Territory and adjacent parts of Western Australia. Minimum temperatures were also above average for most of the country, with the exception of southern parts of Western Australia (2°C to 4°C below average). The highest anomalies were in central parts of New South Wales and south-western parts of the Northern Territory where minimum temperatures were between 4°C to 8°C above average for this time of year.

These temperature anomaly maps show the departure of the maximum and minimum temperatures from their long-term averages. Temperature anomalies are calculated using high-resolution gridded datasets from 1911 onwards. For further information go to Daily maximum temperature for Australia.

Australian Plague Locust

The Australian Plague Locust Commission (APLC) produces a monthly Locust Bulletin during the periods of locust activity (spring, summer and autumn). The bulletin gives regional summaries of the locust situation and weather events of potential significance for locust development. It also provides a forecast of likely developments for the next two months (or from autumn to spring) for the Australian plague locust (Chortoicetes terminifera), spur-throated locust (Austracris guttulosa), and the migratory locust (Locusta migratoria).

According to the APLC, the Australian plague locust population level has remained low over most of eastern Australia throughout the 2017–18 season. Most areas that received rainfall during summer dried out rapidly and prolonged high temperatures are likely to have caused increased mortality of nymphs and adults. Surveys during March recorded low numbers of adults and occasional nymphs in the Central West, Central Highlands and South Central regions of Queensland. Only occasional adults were recorded in most areas of the Riverina, Far Southwest and southern Central West regions of New South Wales.

The outlook for the remainder of autumn is for population densities to remain low in most regions of inland eastern Australia. There a very low risk of swarms affecting any agricultural region during the remainder of autumn. There is a low risk of high density nymph infestations developing in any region during spring (Locust Bulletin April 2018).

Rainfall forecast for the next 8 days

During the next eight days, rainfall is mainly expected in eastern and parts of south-western Australia. Totals between 25 and 50 millimetres are forecast for south-eastern Queensland and coastal parts of northern New South Wales. Similar totals are expected in south-western Western Australia. Little to no rainfall is forecast for the remainder of the country.

This rainfall forecast is produced from computer models. As it contains no input from weather forecasters, it is important to check local forecasts and warnings issued by the Bureau of Meteorology.
