A tropical low pressure that has been stalled near the northwest coastline of Australia since last week will continue to meander over the same region this week.
As a result, copious amounts of tropical moisture will be pumped across parts of northwest Australia before spreading into central Australia as the week progresses.
These daily downpours will result in localized flash flooding along with washed-out roads and railways.
Daily rainfall amounts of 25-75 mm (1-3 inches) are expected which will result in an increased threat for flooding as the week progresses.
While much of this area is sparsely populated, mining and oil production in the region could be impacted by the stormy weather.
A few of the higher population areas that could be severely impacted by the rainfall include Darwin, Broome and Alice Springs.
Due to interaction with land, this tropical low is unlikely to develop into a named cyclone and damaging winds are not expected to be a widespread problem. The highest gusts will be found within thunderstorms and may reach 65-80 kph (40-50 mph).
A potential benefit of this storm system and associated rainfall is that soaking rains could potentially overspread South Australia from Friday into the weekend. While it remains uncertain how much rain will fall in these areas, any rainfall will aid fire fighting efforts as one of the worst outbreaks of wildfires in decades continues across South Australia.
