Dry season floods threaten northern Aus this week

Unseasonably heavy rain and flooding could cut off roads in the Kimberley and central Australia this week.

The satellite images below show a large northwest cloudband extending across Australia on Monday morning. This colossal cloudband, which is being fuelled by tropical moisture from the Indian Ocean, will produce widespread rain over a broad area of Australia this week.

The heaviest rain on Monday and Tuesday will fall over the Kimberley and Interior of WA, and over the Western Interior of the NT. The map below shows the predicted rain during these two days combined.

Flood Watches have already been issued in both states, with some road closures also announced in the Kimberley for the coming days. These include the Gibb River Road, which will close from Tuesday, and Fitzroy Crossing Bridge, which may close later in the week.

On Wednesday, rain will continue over parts of central and northwestern Australia and spread into the nation’s southeast as well.

Later in the week, a second round of heavy rain is expected to develop over the Kimberley and NT from Friday, before spreading towards the east and affecting Qld on the weekend and possibly into the start of next week.

This system will deliver widespread and prolonged rainfall to parts of Australia that typically see little of no rain at this time of year. This will cause out-of-season flooding and may catch some communities and travellers by surprise.

Be sure to check the latest warnings and road closures before travelling across the Australian outback in the next couple of weeks.

A very low wind power week, likely to continue

A stubborn blocking high over southern Australia will make for a very quiet week for wind generation and the pattern behind it isn’t a one-off.   It’s the seasonal signature of a super (very strong) El Niño combined with a positive Southern Annular Mode (SAM), and both the historical record and the current seasonal forecast suggest it’s likely to keep recurring through spring before a potential switch from November.  The setup right […]
