Heavy rain has inundating large parts of northern Queensland, with falls of more than 150 millimetres recorded from Cardwell in the far north and to the region south of Mackay.
The weather bureau says it will be a wet Christmas for the state's north, with heavy rain inundating large parts of the region from Cardwell to the south of Mackay.
Forecaster Ben Annells says there will be no let-up tomorrow.
"Certainly I think there's going to be showers and storms around for today and spreading out to rain at times, and persisting into tomorrow as well, with perhaps the heaviest of the rainfall being in the first part of the day," he said.
Mr Annells says a surface trough off the coast has met an upper trough over the central interior, resulting in the big falls.
"Fairly heavy rainfalls over a 24-hour period around Mackay - up around 130 to 140 millimetres around Mackay and Sarina areas," he said.
"Even up toward Tully around 70 to 80 millimetres as well.
"Certainly some reasonably reasonable rainfall totals over a 24 hour period."
