North Queensland is bracing for isolated falls of up to 250mm on Monday after tropical cyclone Imogen made landfall late Sunday night.

While the system is expected to weaken to a tropical low on Monday, hundreds of homes and businesses have been left without power and roads are closed as flash flooding and damaging wind warnings remain active for the Gulf Country.

It comes after heavy falls on Sunday in which Normanton Airport received 263mm in 24 hours, 186mm of which fell in just six hours.

Bureau of Meteorology meteorologist Ricus Lombard said isolated falls of up to 250mm were forecast for Monday and Tuesday.

“A coastal trough will form around the north tropical coast which will see enhancing showers and storms from Cooktown to Townsville, which will extend to Mackay into the week,” he said.

“Lows are potentially uncertain, but for the next few days we’re pretty confident there will be higher rainfall totals.”

The bureau’s last warning at 4.52am on Monday told residents from Karumba to Gilbert River Mouth, extending inland to Croyden, that gale-force winds of up to 105 km/h had been recorded and were likely to continue.

“Winds should generally ease below gale force during Monday morning as Imogen transitions to a tropical low, but squally thunderstorms with more isolated damaging wind gusts remain possible for the remainder of Monday,” the warning said.

“Heavy rainfall that is likely to lead to flash flooding of low-lying areas and riverine flooding is being observed about the southeast Gulf of Carpentaria coast and adjacent inland and is likely to continue near the cyclone through Monday.

“Heavy rainfall will spread to inland areas of southern Cape York Peninsula on Monday as the cyclone moves further inland.”

Flood warnings are active for the Belyando, Paroo, Bulloo, Thomson, Diamantina, Georgina, Lower Flinders, Normal and Gilbert Rivers.
