GFS and CMC models have picked up on this LOW for a few day now. EC has been a little non commital to anything out there. JTWC and the NAVY SITE are all over it with forecast future winds up to 75knts and issuing a cyclone alert. MMMMMMM I think I might wait until JTWC and the Navy site update cause looking at the MSat Scans at the moment there is nothing overly promising looking that represent a cyclone at the moment. Especially where they are pinpointing it.

Give it 24hrs and the real truth will be spelt out cyclone or no cyclone, Model vs model. All interesting but I am still sitting on the fence as to anyhting forming to a cyclone level just yet. Knock me off the fence JTWC/Navy site if you must but it looks like a dogs breakfast up there at the moment.

REMARKS:
070900Z POSITION NEAR 7.1S 129.3E.
TROPICAL CYCLONE (TC) 19S, LOCATED APPROXIMATELY 345 NM NORTH-
NORTHWEST OF DARWIN, AUSTRALIA, HAS TRACKED EAST-SOUTHEASTWARD AT
11 KNOTS DURING THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS A BROAD, EXPOSED LOW LEVEL CIRCULATION CENTER
(LLCC) WITH DEEP CONVECTION SHEARED TO THE WEST-SOUTHWEST. THE
INITIAL POSITION WAS BASED ON THE MSI. THE INITIAL INTENSITY WAS
BASED ON PGTW AND KNES DVORAK ESTIMATES RANGING FROM 30 TO 45 KNOTS.
A 070120Z ASCAT PASS DEPICTS AN ELONGATED LLCC WITH 30 KNOT WINDS
WRAPPING AROUND THE OUTER PERIPHERY. UPPER LEVEL ANALYSIS INDICATES
THE SYSTEM IS LOCATED NORTH OF THE SUBTROPICAL RIDGE AXIS IN AN AREA
OF MODERATE VERTICAL WIND SHEAR AND MODERATE DIVERGENCE ALOFT. TC
19S IS EXPECTED TO INITIALLY TURN POLEWARD AS A SUBTROPICAL STEERING
RIDGE CENTERED OVER THE TOP END OF AUSTRALIA STRENGTHENS. THE SYSTEM
SHOULD TRACK GENERALLY SOUTHWESTWARD THROUGHOUT THE FORECAST PERIOD
UNDER THIS STEERING INFLUENCE. TC 19S IS EXPECTED TO GRADUALLY
INTENSIFY AS IT TRACKS INTO A MORE FAVORABLE UPPER LEVEL
ENVIRONMENT, CLOSER TO THE UPPER LEVEL RIDGE AXIS. HOWEVER, AFTER
TAU 72, VERTICAL WIND SHEAR SHOULD INCREASE AND CAUSE THE SYSTEM TO
WEAKEN. NUMERICAL MODEL GUIDANCE IS INITIALLY IN GOOD AGREEMENT
UNTIL AFTER TAU 36, WHEN THE MODELS DIVERGE. BOTH GFDN AND GFS
MAINTAIN A MORE POLEWARD TRACK, WHERE UKMO AND NOGAPS MAINTAIN A
MORE WESTWARD TRACK WITH A STRONGER STEERING RIDGE. THIS FORECAST
FAVORS A MORE POLEWARD TRACK AND IS SLIGHTLY SOUTH OF MODEL
CONSENSUS AT THE END OF THE FORECAST. JUSTIFICATION FOR AMENDMENT:
NEW MSI SHOWED THE LLCC TRACKED FARTHER SOUTHEASTWARD BEFORE THE
TURN POLEWARD THAN PREVIOUSLY EXPECTED. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 070600Z IS 10 FEET.//
NNNN

I started a thread in the World section at
http://forum.weatherzone.com.au/ubbthrea..._ad#Post1103444

But, I have posted some Indonesian warnings (not in English) in this thread and I want to keep them separate from the English/Australian thread.

I will leave it to moderators to decide how to handle it

Steven, the appropriate thread in this case is the the Banda one. It's more related to WA than world but I understand why you would wish to create a separate thread (don't get me started on the cyclone lounge...LOL)
