Big wet on the way for Qld in wake of Nora

Earlier Bureau of Meteorology forecasts for the system to produce good rain in Katherine have been downgraded.

Nearly a thousand millimetres of rain has fallen on some parts of the north and far north regions over the past seven days, culminating in an emergency on Monday night when 100mm fell in Cairns in one minute, causing a local levee to break its banks.

Two caravan parks were inundated, with three people taken to hospital with minor injuries while many lost their vans, cars, and personal belongings.

As the clean-up begins in the Cairns region on Wednesday, the area between Ingham and Townsville is bracing for more rain as the low pressure system moves south.

And authorities are warning a second low pressure system in the Coral Sea could combine with ex-tropical cyclone Nora to create a dangerous rain system which could drench the Queensland coast down to the southeast over the Easter weekend.

State Emergency Services Minister Craig Crawford said they were closely monitoring the systems.

"There is potential for high rainfalls for a lot of parts of Queensland this week," Mr Crawford told reporters in Cairns on Tuesday.

"Being a long weekend we're mindful that people could be out camping, fishing and boating, and the message to everyone is please stay tuned to the weather and emergency services, and know what the weather is doing."

Mr Crawford will join Premier Annastacia Palaszczuk on Wednesday on a tour of Cape York communities affected by Nora.

Ms Palaszczuk praised the resilience of the remote centres which regularly weathered severe weather.

"Thankfully there were no injuries or loss of life, but we want to get power restored as quickly as possible," she told reporters in Cairns on Tuesday.

"I just want to see if there's anything else we can do to help. They may be a long way away from Cairns and even further away from Brisbane, but everyone here is part of Queensland."
