SIO- TROPICAL CYCLONE 03S (ABELE)

[wyq614]

is located at 6.4S 89.3E
ECMWF keeps trying to develop something in that area these days.

[Crostorm]

(1) AN AREA OF CONVECTION HAS PERSISTED NEAR 4.2S 88.4E,
APPROXIMATELY 970 NM EAST OF DIEGO GARCIA. THE DISTURBANCE IS
SHOWING PRELIMINARY SIGNS OF CONSOLIDATION DESPITE MODERATE TO HIGH
VERTICAL WIND SHEAR. STREAMLINE ANALYSIS OF THE GRADIENT LEVEL
INDICATES THERE IS A WEAK LOW LEVEL CIRCULATION CENTER EMBEDDED
WITHIN THE MONSOON TROUGH, THOUGH IT IS NOT READILY APPARENT IN
ANIMATED INFRARED OR MICROWAVE IMAGERY. DEEP CONVECTION HAS
INCREASED OVERNIGHT AS THE REGION APPROACHES DIURNAL MAXIMUM.
HOWEVER, THIS CONVECTION IS FRAGMENTED AND UNORGANIZED. A RECENT
AMSU RADIAL HEIGHT CROSS SECTION ALSO SUGGESTS A DEVELOPING WARM
ANOMALY ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10
TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008
MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS POOR DUE TO ADVERSE UPPER LEVEL
CONDITIONS.

REMARKS:
291500Z POSITION NEAR 12.1S 84.9E.
TROPICAL CYCLONE (TC) THREE (03S), LOCATED APPROXIMATELY 700 NM WEST
OF COCOS ISLAND, AUSTRALIA, HAS MOVED WEST-SOUTHWESTWARD AT 05 KTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY
INDICATES THE LOW LEVEL CIRCULATION CENTER (LLCC) HAS CONSOLIDATED
WITH IMPROVED CONVECTIVE BANDING OVER THE PAST 12 HOURS. ANIMATED
WATER VAPOR IMAGERY SHOWS A COLD DENSE OVERCAST DEEPENING OVER THE
LLCC WITH IMPROVED POLEWARD OUTFLOW. THE CURRENT POSITION IS BASED ON
A 291130Z SSMI-S MICROWAVE IMAGE. THE CURRENT INTENSITY IS BASED ON A
DVORAK ESTIMATE OF 35 KTS FROM PGTW. THE LLCC IS LOCATED JUST
EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS UNDER MODERATE VERTICAL
WIND SHEAR (VWS). TC 03S IS TRACKING ALONG THE NORTHWEST PERIPHERY OF
A LOW TO MID-LEVEL SUBTROPICAL RIDGE TO THE SOUTH. IT IS EXPECTED TO
MOVE ON A MORE SOUTHWARD DIRECTION OVER THE NEXT 12 HOURS IN RESPONSE
TO AN APPROACHING MID-LATITUDE TROUGH. AS THE TROUGH PASSES TO THE
SOUTH, TC 03S WILL RECURVE AND ACCELERATE TO THE SOUTHEAST AND WEAKEN
AS VWS INCREASES. THE LIMITED NUMERICAL GUIDANCE IS IN OVERALL
AGREEMENT WITH THIS TRACK FORECAST WITH GFDN FAVORING A MORE EASTWARD

TROPICAL CYCLONE (TC) THREE (03S), LOCATED APPROXIMATELY 740 NM WEST
OF COCOS ISLAND, AUSTRALIA, HAS MOVED SOUTHWESTWARD AT 06 KNOTS
OVER THE PAST SIX HOURS. ANIMATED INFRARED (IR) SATELLITE IMAGERY
DEPICTS TIGHTLY CURVED LOW LEVEL BANDING WRAPPING INTO AN ELONGATED
LOW LEVEL CIRCULATION CENTER (LLCC) WITH DEEPENING CENTRAL
CONVECTION. THERE IS LOW CONFIDENCE IN THE CURRENT POSITION BASED ON
THE ELONGATED NATURE OF THE LLCC IN RECENT MICROWAVE IMAGERY AND A
POSSIBLE SECONDARY CIRCULATION TO THE EAST OF THE MAIN CONVECTION.
THE CURRENT INTENSITY IS BASED ON DVORAK CURRENT INTENSITY (CI)
ESTIMATES OF 35 KNOTS FROM PGTW AND KNES. UPPER LEVEL ANALYSIS
INDICATES TC 03S IS LOCATED JUST EQUATORWARD OF THE SUBTROPICAL
RIDGE (STR) AXIS IN AN AREA OF ENHANCED UPPER LEVEL DIFFLUENCE AND
MODERATE (15 TO 20 KNOTS) OF VERTICAL WIND SHEAR (VWS). TC 03S IS
CURRENTLY TRACKING ALONG THE NORTHWESTERN PERIPHERY OF A LOW TO MID-

My thoughts on 03S, along with some daily stuff from the West Pac.

[youtube]http://www.youtube.com/watch?v=1rWkrK6hMcc[/youtube]

[Reesie]

Potential Cyclones:
At midday, a weak low [02U] was located near 11.4S 86.1E. Although the low may
develop over the next two days it is expected to remain west of 90E. On Thursday
the system may approach 90E.

Likelihood of this system being a tropical cyclone in the the Western Region:
Tuesday :Very Low
Wednesday :Very Low
Thursday :Low

http://www.bom.gov.au/wa/forecasts/nwcyclone.shtml

Interesting, why would they number something not in their area?

From what ive gathered from email discussions with senior BoM forecasters. Should they think a Tropical Low could become a tropical cyclone within the Australian region as a whole then they number it. Examples include Bernard & Innis 2008-09 and Imani 2009-10.
