The Australian Bureau of Metrology is reporting significant rainfall this weekend due to a deep low pressure. There will be a cloud band over northwestern Australia as a cold front moves up from the Southern Ocean.

Good for farmers

This front is currently developing in the northern Great Australian Bight, prompting BOM to issue severe weather warnings, including flood warnings.

Bureau National Operations Centre Director Dr Andrew Tupper said in a BOM press release that the rainfall will be positive for farmers and those in the agricultural industry.

"This is the first widespread rainfall this autumn and a welcome start for the southern crop and pasture growing season," Dr. Tupper said.

Although this is good news for some, this cold front is also expected to be an unusually large-scale weather event, which carries with it some significant risks, reports BOM.

Rainfall rates overall

While this weather could bring with it some potential issues, overall it will greatly help lots of regions that are in need of water for crops and their water tanks.

BOM's previous annual climate data from 2015 shows a decline from previous years, reflecting global changes connected to rising global temperatures. For the year, the nationally averaged rainfall fell 5 per cent below average. This was at 443.7 millimetres in comparison to the 1961 to 1990 average which was 465.2 mm.

Paying attention to weather reports

BOM's Dr. Tupper warned Australians to be careful this weekend, as heavy falls of rain on Friday, Saturday and Sunday will significantly affect the Interior districts of Western Australia, Kimberly and Eastern Pilbara.

The potential risk from flooding can be reduced by paying close attention to weather reports, advises BOM.

"Whatever your plans for this weekend whether inland, near a river, on a coast, or on the sea we advise members of the public to pay close attention to official forecasts and warnings, including flood warnings." Dr Tupper said.
