A rain band will form over Australia this week bringing heavy and "unseasonable" rain to much of the country's northern coast.
The return of the wet weather comes less than a week after the Bureau of Meteorology (BoM) declared an end to La Niña, and a welcome June dry spell.
An "injection of tropical moisture" provided by this large cloudband will help produce rain over a broad area of eastern Australia, from Sydney to Townsville.
Weatherzone warned some areas of Northern Territory and Queensland could see "several months' worth of dry-season rainfall", with eastern New South Wales also set for a soaking.
"A few showers will develop over the NT and far west QLD on Tuesday and Wednesday as a cloudband starts to build across northern Australia," the weather service said.
"Rain will become heavier and more widespread between Thursday and Saturday as the cloudband slowly drifts further east.

"This rain event could cause flooding in parts of the NT, QLD and eastern NSW, including areas that are normally dry at this time of year."
The rain is forecast to persist into the weekend and "possibly into the start of next week as well."
Northern Territory is currently in it's dry season, which runs from May to October.
Typically the Territory and outback Queensland will receive less than 5mm of rain during this period, however modelling shows up to 100mm could fall over a seven day period.
