Cyclone Charlotte was yesterday downgraded to a tropical low after crossing the western coast of Cape York early in the morning.

But there is no respite in sight for North Queensland residents as "phenomenal" amounts of rain continue to hit the area, with Cairns receiving 278mm yesterday.

A severe weather warning is in place for people on the north tropical coast, and in the Tablelands, Herbert and Burdekin regions, with monsoonal rains forecast.

And a severe weather warning was also issued this morning for the Goldfields, Flinders and North West regions as the low is expected to today start tracking towards flood-ravaged Mt Isa.

Flood warnings are current for the Diamantina, Georgina, Nicholson, Albert, Cloncurry, Flinders and Norman Rivers as well as Eyre Creek.

Bureau of Meteorology senior forecaster David Bernard said: "It's no longer a cyclone but it's still producing significant weather in the surrounding region, from Cooktown to Bowen."

"There's been some phenomenal rain of over 400mm in places around Cairns."

Simone Roseler, a resident of Yorkeys Knob, north of Cairns, said the deluge had cut off her suburb.

"This morning our street was like one big, flowing river and we were scared our car was going to float away," Ms Roseler said.

"And the canefields look like lakes."
