The remnants of Tropical Cyclone Dianne will spread rain over a broad area of central and eastern Australia this week, dumping more water into already flooded rivers across several states and territories.

The satellite images below show widespread cloud over central and northern Australia on Monday morning. The cloud over the country’s interior is associated with the remnants of Tropical Cyclone Dianne, which made landfall over the Kimberely coast early on Saturday morning and has since weakened and moved over WA’s North Interior.

The cloud associated with the remnants of Dianne will cause heavy rain to spread over central Australia on Monday. This has prompted severe weather warnings for heavy rain and flash flooding in parts of the WA Interior and the NT’s Tanami and Lasseter districts.

Cloud and rain will spread further east from Tuesday to Thursday, soaking parts of the NT, SA, Qld and northern NSW. Rain and storms from this system should then contract to northern and central Qld from Friday before easing over the weekend.

This week’s rain will be enough to cause or exacerbate flooding across a broad area of central and eastern Australia. On Monday morning, flood watches and flood warnings were in place in districts spanning more than 3000 km across Australia, from the WA Interior to the nation’s east coast.

The flooding that will be caused by the rain falling this week, combined with the rain that inundated river systems in recent weeks, is likely to cause significant river, creek and stream level rises. This may cause overland inundation that could affect roads and railway lines, possibly isolating communities and homesteads.
