The Department of Fire and Emergency Services is warning people in the west and north Kimberley to prepare for possible flooding in the next 24 hours.
Significant river rises and widespread flooding are expected in the Lennard, Isdell and Price Regent rivers in the west Kimberley including the Cape Leveque area.
In the northern Kimberley, people in Kalumburu and surrounding communities need to take action for possible flooding.
Significant stream rises and localised flooding are expected in the King Edward, Drysdale and Pentecost rivers.
Main Roads' Lana Powell says some of the flood ways are too deep to cross.
"A couple of the flood ways are about 600 metres wide and 900mm deep," she said.
The Water Corporation says Kununurra's sewerage system is working, but the system is struggling to cope with extra water.
Shire of Wyndham East Kimberley CEO Gary Gaffney says the forecast is for yet more rain.
"It's raining heavily, it's raining consistently over the last 24 hours," he said.
"The Microwave Hill Tower rain station, which is on top of Kelly's Knob had over 200mms of rain."
The shire is warning parents to keep children away from fast-flowing drains for safety reasons.
