Not many weather systems can produce rain in every Australian state and territory at the same time. But this week, that’s exactly what a northwest cloudband and deep low pressure system have been doing.

The satellite image below shows the situation on Thursday afternoon, with Weatherzone's satellite-derived rainfall layer (Oracle) included to show where the rain is falling.

The thick cloud draped over NSW, Queensland and the NT is the northwest cloudband. This feature has traversed the country during the last several days, causing widespread rain and some flooding.

The speckled cloud over southern Australia is being caused by cold air that has been driven up from the Southern Ocean by a strong low pressure system. This low has also been causing damaging winds in South Australia during the last two days, including wind gusts of 109km/h at Cape Willoughby and 93km/h at Strathalbyn.

Here are some of the standout 24-hour rainfall observations from each state and territory this week:

• WA: 48mm at Mandora - three months’ worth of rain at this time of year
• NT: 10.4mm at Uluru - enough to cause waterfalls on the monolith
• SA: 17.4mm at Streaky Bay – now having wettest June in 12 years
• TAS: 30mm at Lorinna – wettest day so far this winter
• VIC: 116mm at Mt Buffalo – wettest in the country during 24 hours to 9am Thursday
• NSW: 85mm at Perisher Valley – wettest day since 2017
• ACT: 11mm at Canberra – now wettest June in five years
• QLD: 34mm at Windorah – wettest day in 15 months

Both the northwest cloudband and the low pressure system will continue to cause rain over multiple states and territories during the remainder of this week.

Most of the rain between now and Sunday will fall over southern and eastern Australia (see image below), although a separate cold front will bring another burst of showers and storms to the west coast on Sunday.

More severe weather and flooding is possible over the next few days, so be sure to check the warnings in your area.
