A transition to a tropical low is expected soon, but heavy rainfall and localised damaging winds remain possible with 262mm of rain reported in Normanton.

The warning zone is from Karumba to Gilbert River Mouth, extending inland to Croydon.

TC Imogen remains a Category 1 with winds near the centre of 75kph with wind gusts to 100kph. .

It is located 65 kilometres east of Normanton and 90 kilometres northwest of Croydon and moving east southeast at 21 kilometres per hour.

Imogen crossed the Gulf of Carpentaria coast just to the north of Karumba at about 9pm Sunday evening.

It is expected to continue moving east-southeastwards in the short term, taking it further inland today. The system has recently maintained its strength over land, but later this morning is expected to gradually transition to a tropical low. Longer term, the system is expected to track more slowly to the southeast towards the North Tropical and Herbert-Lower Burdekin coasts as a deep tropical low.

Gales with wind gusts to 105 km/h have been recently observed around Normanton and are likely to continue to extend out to about 80 kilometres from the centre of the cyclone for the next few hours. 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.

Ergon Energy said aircraft and crews were on standby to fly to Mornington Island as soon as the pilot gives the green light after 180 customers were impacted.
