UPDATE, 11.20am: Tropical Cyclone Iris has re-formed in the Coral Sea, a day earlier than predicted.

The Bureau has just issued an update, saying Tropical Cyclone Iris (Category 1) with central pressure 995 hPa was located over the Coral Sea near latitude 16.9 south longitude 148.7 east, which is about 310 km east of Cairns and 330 km northeast of Townsville.

The cyclone is moving southwest at 13 kilometres per hour.

Tropical cyclone Iris has redeveloped in the Coral Sea off the tropical Queensland coast.

Tropical cyclone Iris is expected to continue moving southwest for most of the day today, before becoming slow moving tonight. On Tuesday the system is expected to turn east and move away from the Queensland coast. It may develop further, but is not expected to cross the Queensland coast.

Damaging wind gusts and heavy rainfall are possible about coastal and island areas between about Rollingstone and Sarina as the cyclone makes its closest approach to the coast.

Earlier:

THE Bureau of Meteorology has increased the chances of ex-tropical cyclone Iris reforming on Tuesday.

Cyclone development has been set at high on Tuesday (a more than 50% chance) with Proserpine, Bowen, Townsville, Hamilton Island, Ingham and Innisfail the locations which may be affected.

Damaging winds, with peak gusts in excess of around 100km/h, may develop about the coast, islands and higher terrain within the warning area during Monday evening or Tuesday morning.

Heavy rain, which may lead to flash flooding, is also expected to develop from Monday evening.

The Bureau of Meteorology states at 4am this morning, ex-tropical cyclone Iris was located approximately 400km east-northeast of Cairns and moving slowly south-southwest at 8km/h.

It is expected to move southward and track closer to the coast today and Tuesday.

 

 

There remains some level of uncertainty regarding its movement and development over the coming days with six hour totals of 100 to 150mm are likely with local falls up to 250mm possible and 24 hour totals of 200 to 300mm are expected.

A severe weather warning is in place with ex-tropical cyclone Iris expected to bring damaging, and possible gale, winds and heavy rainfall to the Mackay region.

Oz Cyclone Chasers said the system is developing fairly quickly and therefore will likely respond to upper level West to North Westerly winds that will want to stall the system and move it east from tomorrow onwards.

"The system is developing fairly quickly and therefore will likely respond to upper level W-NW winds that will want to stall the system and move it east from tomorrow onwards.

"There are still ensemble runs inside the EC modelling that bring the system very close to the coast, however overall there has been a large trend overnight to the east.

"It will all come down to how close to the coast the system will get as to what wind and rain we will see. As always though we can't rule out a coastal crossing especially in this situation where the unpredictability has been so high."

 

 

Meteorologist Dean Narramore said it's going to be a "wet and windy day" for Mackay today.

In the last 24 hours, the Mackay region has had 30 to 50mm of rainfall in most parts of the region, with Mt Pleasant receiving the most (50mm).

But further west, Mt William recorded 106mm.

Mr Narramore said the rainfall was expected to continue throughout the week.

Central Coast and Whitsundays forecast

The Bureau of Meteorology states ex-tropical cyclone Iris lies over the northwest Coral Sea and should move to the southwest today and tomorrow, before adopting a more easterly track on Wednesday.

The low has a high chance of redeveloping into a tropical cyclone tomorrow, but is expected to remain offshore of the Queensland coast.

A high in the Tasman Sea will extend a weak ridge over eastern Queensland. A new high over the Great Australian Bight will move east and over the Tasman Sea on Tuesday, reinforcing the ridge.

Some showers and the chance of isolated storms will occur over east coast districts in the onshore wind flow to the south of ex-tropical cyclone Iris.

Showers, rain areas and isolated storms are likely to become further enhanced with possible heavy falls about the east tropical or central coast and nearby inland early next week as the system approaches the coast.

Queensland Fire and Emergency Services advises that people should:

Move your car under cover or away from trees.

Secure loose outdoor items.

Seek shelter, preferably indoors and never under trees.

Beware of fallen trees and powerlines.

Never drive, walk or ride through flood waters. If it's flooded, forget it.

Keep clear of creeks and storm drains.

For emergency assistance contact the SES on 132 500.
