The low, which currently sat 380 kilometres to the east of Cairns, was expected to cross the coast today.
Bureau of Meteorology warnings are in place for flash flooding between the ranges of Grenville and Port Douglas, Gordonvale and Ingham and coastal catchments between Cooktown and Ingham.
RACQ spokesperson Lucinda Ross said people should be aware of the risks of flash flooding across roads and play it safe.
“There is plenty of water so we’re urging those in the path of this system to avoid the roads if they can and never drive, walk or ride through flood waters,” Ms Ross said.
“There’s also high winds in these areas today, so secure loose items around your home, move your car away from under cover and away from trees and beware of fallen trees and powerlines.”
