#1 Postby Craiga74 » Wed Dec 09, 2009 11:19 am

Not much to talk about just yet with this one....but things will be looking a lot different in a few days when it gets out over the warm soupy waters in the Timor Sea at present

I think this is the system that the Euro has been developing with consistency for the last few days, it may become the strongest southern hemisphere TC of the year

Euro 96 hours

Euro 240 hours

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.1S
135.8E, IS NOW LOCATED NEAR 10.8S 132.7E, APPROXIMATELY 150 NM
NORTHEAST OF DARWIN, AUSTRALIA. A 100853Z SSMIS IMAGE SHOWS POORLY
ORGANIZED DEEP CONVECTION ABOUT A DEVELOPING LOW LEVEL CIRCULATION
CENTER (LLCC). LOCATED UNDER THE SUBTROPICAL RIDGE AXIS, THE SYSTEM
IS UNDER LOW VERTICAL WIND SHEAR AND HAS DIFFLUENT FLOW ALOFT.
ADDITIONALLY, THE AMSU VERTICAL CROSS-SECTION DEPICTS AN INCREASING
ONE-DEGREE TEMPERATURE ANOMALY. FINALLY, THE GLOBAL MODELS OF
NOGAPS, GFS AND ECMWF CONTINUE TO DEVELOP THE SYSTEM INTO A
TROPICAL CYCLONE OVER THE NEXT COUPLE OF DAYS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO FAIR.

TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 10.8S
132.7E, IS NOW LOCATED NEAR 11.8S 132.2E, APPROXIMATELY 90 NM EAST-
NORTHEAST OF DARWIN, AUSTRALIA. WHILE THE GLOBAL MODELS CONTINUE TO
DEVELOP THIS AREA, DEVELOPMENT IS NOT EXPECTED WITHIN THE NEXT DAY.
THE LLCC IS WEAK AND PARTLY OVER LAND AS INDICATED BY OBSERVATIONS
AND RADAR DATA FROM THE NORTHERN TERRITORY. SEA LEVEL PRESSURES
ALONG THE COAST RANGE FROM 1004 TO 1007 MB WITH NO SIGNIFICANT 24
HOUR PRESSURE TRENDS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO POOR DUE
TO A WEAK CONVECTIVE SIGNATURE AND LAND INTERACTION.

"Tropical Low" is the official designation for the system, so surely that (rather than "Low Pressure") should be in the topic name.

NM EITHER SIDE OF A LINE FROM 12.3S 131.4E TO 12.9S 127.2E WITHIN THE
NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF
NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA
ARE ESTIMATED TO BE 22 TO 27 KNOTS. METSAT IMAGERY AT 112030Z
INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 12.5S 131.0E. THE

REMARKS:
Tropical low 01U has tracked steadily southwest just inland of the western Top
End coast and at 06Z was located by radar north of Daly River Mouth. The area of
strongest winds measured on Doppler radar south of the low's centre has moved
southwest from the Darwin area towards Channel Point. The low was assessed at
Dvorak FT=MET=PAT=2.5 at 06Z and is forecast to move west into the Timor Sea,
under the influence of a low-level ridge over the continent. The low is forecast
to develop into a tropical cyclone early on Sunday, then intensify further in a
favourable environment. The cyclone is expected turn south or southwest and
approach the western Kimberley coast on Monday or Tuesday.

REMARKS:
Tropical low 01U has become slow-moving over the last few hours and is becoming
difficult to locate accurately on radar. Overall, convection has diminished
during the past 6 hours, however, new deep convection has recently begun to
flare up on the western flank of the system. Dvorak assessment has been
difficult due to ragged convection, with DT indeterminate. Trend is S or D-
during the past 24 hrs, but expected to follow a D trend from now on as the
system moves away from the coast and convection consolidates overnight. The low
is forecast to move west into the Timor Sea, and develop into a tropical cyclone
on Sunday morning, then intensify further in a favourable environment. The
cyclone is expected turn south or southwest and approach the western Kimberley
coast on Monday or Tuesday.
