NORMANTON has copped the brunt of Tropical Cyclone Imogen with 262mm of rain falling as the system crossed the Gulf.
The first tropical cyclone of the season made landfall as a Category One storm just north of Karumba about 9pm, cutting power, felling trees and bringing widespread rain.
Normanton enjoyed the highest rainfall with 262mm falling in the 24 hours to 9am - with 186mm recorded in the town in just six hours to 3am.
A wind gust of 100km/h was also recorded at Normanton.
Bureau of Meteorology meteorologist Pieter Claassen said the high rainfall totals recorded in Normanton were extremely rare.
"Every year at Normanton we have about a 1 per cent chance of seeing rainfall rates that high, so this is a pretty high rainfall event for them."
Cyclone Imogen was this morning continuing to track to the east, south-east across the Gulf as a Category One system.
Mr Claassen said the system was likely to be downgraded to a tropical low later today, however heavy rain was expected to impact the coastal area from Cooktown to Townsville as the deep tropical low moved south.
"It is still currently a Tropical Cyclone over the next few hours it is likely to be downgraded to a low as it moves east over the northern Goldfields.
"As it moves eastwards we will see enhance rainfall in the Goldfields and in particular the tropical coast from Cooktown to Townsville, with the heaviest falls over the next day or so."
Mr Claassen said rainfall totals of 150-200mm could be recorded over six hours in that coastal region, with isolated falls of up to 300mm in six hours possible in the area.
He said thunderstorms may develop around the low which would lead to increased rain across both coastal and inland parts of North Queensland this week.
Flood warnings remain in place for a large part of Queensland including moderate warnings for the Belyando and Thomson rivers, and minor warnings for the Bulloo, Georgina, Lower Flinders, Paroo, Diamantina, Norman and Gilbert rivers.
The cyclone has cut power to several towns in the Gulf, with Ergon Energy crews working to restore electricity to over 1000 customers in the Normanton and Karumba areas.
A crew from Atherton will fly to Mornington Island this morning to restore power to 180 customers at Gununa.
An Ergon spokeswoman said crews would do aerial patrols of the high-voltage network as soon as it was safe assess the damage.
