SPAC: YASI (14U /11P) - Severe Tropical Cyclone
Moderator: S2k Moderators
Still holding a surprisingly good circulation there with also a fairly impressive looking convective curl, I'm guessing its just become a inland tropical low that you sometimes gt, much like those African waves you get in the Atlantic basin.

SEVERE WEATHER WARNING
for Damaging Winds and Flash Flooding.
For people in the Gulf Country and Northwest districts and northwestern parts of
the Channel Country district.
Issued at 9:40 pm on Friday 4 February 2011
Synoptic Situation: At 9pm, Ex-Tropical Cyclone Yasi was located over the
Northern Territory about 350 km southwest of Mount Isa and was moving west
southwest at about 18 kilometres per hour. The tropical depression is expected
to continue moving west southwest away from Queensland overnight and through
Saturday.
Damaging wind gusts of up to 90 km/hr are possible over the Northwest district
and northwestern parts of the Channel Country district. These wind gusts are
forecast to contract southwest into the Channel Country district west of Boulia
to Birdsville during Saturday morning before contracting further west into the
Northern Territory Saturday afternoon.
Rain areas and thunderstorms with locally heavy falls are expected to continue
through areas west of about Normanton to Cloncurry to Boulia overnight,
contracting to areas near the Northern Territory border south of Camooweal
Saturday morning and west of the Northern Territory border by late Saturday
afternoon. Heavy rainfalls may lead to flash flooding and fast river rises in
these areas.
The Severe Weather Warning for western parts of the Central West district and
far western parts of the Northern Goldfields district has been cancelled.
Rainfall: Highest rainfalls since 9am have been 68mm at Camooweal, 41mm at
Urandangi and 39mm at Mount Isa.
A separate Flood Warning is current for Leichhardt, Gilbert, Norman and Flinders
Rivers.
The State Emergency Service advises that people in the affected area should:

The only I didn't like was that the reporter said that people in New Orleans had virtually no warning. WTH is he talking about?

By the way, taking landfall point (Mission Beach, Queensland) and the last given position at 1200 UTC from the BOM (23.0S 137.3E), we get a distance/bearing of 237°/1080 km (671 miles).
To put this into context, it'd get you to near Indianapolis if a storm hit Louisiana, or it'd get you to Murphy, North Carolina if a storm hit NYC and travelled at the same bearing.

Tropical Cyclone Yasi the second most damaging storm in Australia’s history
Tropical Cyclone Yasi has dissipated, but the damage totals from the storm make it Australia’s second most expensive tropical cyclone of all-time, according to Tropical Storm Risk, Inc. The storm’s $3.5 billion price tag is second only to Cyclone Tracy, which hit Darwin on Christmas Day 1974, doing $3.6 billion in damage (2011 dollars.) Yasi roared inland over Queensland, Australia at 12:30am local time on Thursday as a strengthening Category 4 storm with 155 mph winds and a 930 mb central pressure. The cyclone missed the most populous cities on the coast, Cairns and Townsville, but damaged up to 90% of the buildings in the small towns near where the eye passed–Tully, Mission Beach, and Cardwell. A storm surge of 5.4 meters (17.7 feet) was observed at Cardwell, and there was substantial surge damage at the coast. Fortunately, the storm surge hit near low tide, resulting in a storm tide–the height of the water above land–of about 4.5 meters, more than 2 meters below what would have occurred had Yasi hit at high tide. Yasi moved quickly enough across Queensland after landfall so that major flooding was limited to just three locations near the coast. Yasi’s central pressure of 930 mb at landfall made the storm the most intense recorded in Queensland since at least 1918, and possibly since 1899. In 1918, there were two cyclones (at Mackay and Innisfail) with measured pressures in the upper 920s/low 930s, but it is quite plausible that the minimum central pressures were lower than that. The 1899 (Mahina/Bathurst Bay) cyclone had a measured pressure (ship near shore) of 914 mb.

Is there any chance it could completely cross Australia and develop in the South Indian? Does it retain Yasi if it stays in the SIO or take a new name?
Using its distance it has penetrated, such conditions in recent significant US landfalls with long land tracks (based on best track distance only) would have been felt in:
Isabel 2003 - near Sudbury, Ontario
Charley 2004 - near Norfolk, Virginia (assumed it was over land the whole time)
Frances 2004 - near Johnson City, Tennessee
Ivan 2004 - near Pittsburgh, Pennsylvania
Jeanne 2004 - near Raleigh, North Carolina
Dennis 2005 - near Fort Wayne, Indiana
Katrina 2005 - near Columbus, Ohio
Rita 2005 - near Springfield, Illinois (it was absorbed by a front by then I believe!)
Gustav 2008 - near St. Louis, Missouri
Ike 2008 - near Terre Haute, Indiana

the computer model consensus has it moving slowly west but don't take it across Australia, and it will keep its name. Yasi was classified in the Fiji region and crossed into the Brisbane region and kept its name. A few years ago, don't know exactly when, the practice of renaming the systems was abandoned.
