A flood watch has been issued from Rockhampton all the way down to the NSW border.

The warning for minor to moderate flooding from late Sunday also extends to the Darling Downs.

Falls of more than 200 millimetres are expected in parts, including creeks and rivers still swollen from the recent deluge.

Already swollen creeks and rivers in South-East Queensland could be in for more flooding.

Heavy rain is expected from late Sunday through to Tuesday.

Some areas could cop over 200 millimetres.

Weather guru Justin Noonan told Neil Breen it was a complex system and hard to predict.

“When we get into Sunday that’s when things are going to take a bit of a turn for the worst, we have got a bit of a complicated system here.

“We are going to have a coastal trough or maybe even a low pressure system develop around that Rockhampton, Capricorn Coast, and it’s going to move south and head into the Wide Bay and south east coast.”

He said there could be heavy showers and gale force winds.

The Bureau of Meteorology’s James Thompson told 4BC News it could spark a repeat of flooding seen in some rivers of the south-east recently.

“A lot of those rivers and creeks did get flooding through the last couple of weeks, and will respond really quickly to any rainfall, so some of those catchments are in the flood watch as well as some others a little bit further north that also have a risk of heavy rainfall.”

He said there was a lot of uncertainty where the heavy falls could be.

In Brisbane, it’s a wet weekend ahead:

Saturday – medium chance of rain, top of 25

Easter Sunday – very high chance of rain, top of 23

Easter Monday – very high chance of rain, top of 24

#EasterWeekend is looking a bit damp across eastern #qld, with a flood watch current, including #Brisbane.
