WEAK AND THIN RAINBANDS COMMENCE TO REACH QUEENSLAND COAST. THE RAIN SHOULD GET MORE INTENSE AS THE CYCLONE GROWS CLOSER. ONLY FOR VISIBLE PURPOSES, I WOULD LIKE THE CYCLONE TO MAKE LANDFALL NEAR A RADAR LOCATION TO TRACK IT USING THE RADAR.

Coast prepares for 'spooky' cyclone
A CYCLONE as powerful as the storm that devastated Darwin 30 years ago was heading toward the Queensland coast today, with weather forecasters unable to accurately predict where it would strike.
Cyclone Ingrid is rated a powerful category five and has a compact centre with winds gusting up to 290km/h – drawing comparisons with Cyclone Tracy, which hit Darwin on Christmas Eve 1974.
The Tropical Cyclone Warning Centre in Brisbane said today the cyclone was about 290km northeast of Cooktown and moving west at 8km/h.
Warning centre supervising meteorologist Phil Alford said the cyclone had a very destructive core.
"Where Tracy was a category four, this is a category five," he said.
"It is a deeper cyclone but with a very concentrated sort of vortex."
Warnings for the far north Queensland coast between Port Douglas and Cairns are being issued every three hours.
Mr Alford said computer models had been unable to accurately predict where the cyclone was likely to cross the coast.
"Because of that that we've got a fairly large warning zone from Lockhart River to Port Douglas," Mr Alford said.
"But one thing is for sure. All models say it's going to cross the coast – none of them are saying it's going to turn around and head off towards New Zealand or something."
Mr Alford said it was possible the cyclone could turn more westerly or even south-westerly and pick up speed by tomorrow, when an upper level trough that was impeding it moved away.
Terry Dukes, the reporting officer and weather observer at Cooktown Airport, said weather conditions today were fairly normal, but people were preparing for the worst.
"This one's a bit spooky," Mr Dukes said.
"The cloud hasn't moved for the last two or three hours as far as coming towards us so it tells me that whatever it's doing it's possibly going a little bit to the north-west.
"If it keeps going that way we are happy," Mr Dukes said.
Federal Liberal MP Warren Entsch, whose far north Queensland electorate of Leichhardt is in the path of the storm, has warned locals not to be complacent.

Cape Melville isn't a city; it's a National Park.
There's almost no actual towns or cities north of Cooktown, and even Cooktown only has a population of about 1,000.
This is fortunately a very, very, very, very, very, very thinly populated area that will be hit by Ingrid, in many cases TOTALLY unpopulated. It makes the Big Bend area of Florida look like the coast of New Jersey.
It's obviously going to miss Cairns and that's the only city of consequence anywhere near it.

Name: Ingrid
Severity Category: 5
Situation At: 1PM EST Tuesday 8 March 2005
Warning Area: Lockhart River to Port Douglas
Watch Area: Port Douglas to Innisfail, and extending inland to Palmerville
Location: 13.9S 147.2E
Recent Movement: W at 8 km/h
Remarks: Severe Tropical Cyclone Ingrid continues to move west and poses a serious threat
to the far north Queensland coast. Ingrid has a very destructive core with wind gusts to 290 km/hr.
Gales are expected to develop between Lockhart River and Port Douglas during Wednesday morning with destructive winds possible later in the day.
Tides in coastal areas between Lockhart River and Port Douglas are likely to exceed the highest tides of the year as the cyclone approaches.
People in near coastal areas between Lockhart River and Port Douglas should immediately commence or continue preparations, especially protecting boats and property using available daylight hours.
People further inland to about Palmervile, and those in near coastal areas between Port Douglas and Innisfail, should consider action they will need to take if the cyclone threat increases and listen to the next advice at 5pm EST.
Marine users please note: Warnings specific to the marine community are contained in Coastal Wind Warnings and Ocean Wind Warnings. Refer to those warnings for the winds associated with Tropical Cyclone Ingrid.
The next track map will be issued by 5pm EST Tuesday 8 March.
WATCHES EXTENDED INLAND, THERE IS A POSSIBILITY THAT IF THE CYCLONE GOES MORE WESTWARD, IT COULD CROSS THE PENINSULA OF YORK AND END UP IN THE GULF OF CARPENTARIA. BUT, THIS WOULD BE GOING AGAINST THE FORECAST OF THE JTWC.

Excuse my geographical misunderstanding, and fortunately the area is not very populated. So, if everything goes as expected this landfall could be compared to the one Hurricane Bert did in 1999 in southeast Texas. Unfortunately, the cyclone is staying too much long over the Great Barrier Reef and this could be dangerous for the reef.

What we have here is the landmass forming convection to the south of the cyclone(Day time heating). We got very much a cat5 here.
IMO, Ingrid is, and possibly always will, fall short of the category five status.
I'd like to see Dvorak estimates a little higher than 6.5 before flying my "cat five" freak flag.
