[Chacor]

UPDATED
Australian Government Bureau of Meteorology
Western Australia

TROPICAL CYCLONE OUTLOOK FOR THE CENTRAL INDIAN OCEAN
Issued at 6:11pm WDT on Monday the 12th of November 2007
For the area between LONGITUDES 90 - 110 EAST

Tropical Low
Location :near 4S 93E
southwest of Sumatra, approximately 1000 kilometres north
northwest of the Cocos Islands.
Central Pressure :1004hPa
Recent movement :slowly west southwest

DEVELOPMENT POTENTIAL
Tuesday : low
Wednesday : low
Thursday : low

REMARKS - Most likely movement of the low is towards the southwest or west
southwest. The system is likely to persist as a weak tropical low over the next
three days but conditions are not favourable for development into a tropical
cyclone within the next three days.

** NOTE: Development potential is an estimate of the probability of **
** tropical cyclone development within a 24 hour period. **
** LOW = 10% or less MODERATE = 20-40% HIGH = 50% or more **

Dangit, Chacor, you beat me to this.

This is in Jakarta's area, so if there's a name list, they might want to announce it pretty soon whether this remains in the area or not.

TROPICAL CYCLONE OUTLOOK FOR THE CENTRAL INDIAN OCEAN
Issued at 12:45pm WDT on Tuesday the 13th of November 2007
For the area between LONGITUDES 90 - 110 EAST

Tropical Low at noon WDT
Location :near 5.4S 93E
southwest of Sumatra, approximately 900 kilometres north
northwest of the Cocos Islands.
Central Pressure :1002hPa
Recent movement :slowly southwest

DEVELOPMENT POTENTIAL
Wednesday : high
Thursday : high
Friday : high

REMARKS - The low has shown some recent indications of development which is
expected to continue given that favourable conditions are expected in the next
day or so. While the low is not expected to develop into a tropical cyclone
intensity today [Tuesday], there is now a high chance of cyclone intensity being
reached on Wednesday and the following two days. The most likely movement of the
low is towards the southwest.

Is there another location other than http://www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDW10900.txt from which to get these advisories? The ".pl?" screws up my archiving program and WebCite. I tried locating it via Twister, but to no luck.

Which they have just done despite it not being in their AOR. Has anyone been able to get into the TCWC Jakarta site the last couple of days? The page that would have this sort of thing on will not load for me.

REMARKS:
The system has developed in curvature during the last 12 hours in an environment
of low shear and favourable upper level outflow to the south. While convection
has taken some time to become organised, a ship to the south of the system has
reported 35 knots suggesting TC intensity has been reached. Dvorak based on 0.6
wrap.
Further development is expected in the next 24 hours with a southwesterly motion
likely to continue.

The next bulletin for this system will be issued by: 14/1900 UTC by Perth TCWC.

[Coredesat]

At this point I'm wondering if TCWC Jakarta is even operational at the moment. The system should have been given one of its (unannounced) names.

SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
100 NM EITHER SIDE OF A LINE FROM 8.3S 91.9E TO 10.5S 88.6E WITH-
IN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY IS-
SUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS
IN THE AREA ARE ESTIMATED TO BE 28 TO 32 KNOTS. METSAT IMAGERY AT
141430Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 8.7S
91.6E. THE SYSTEM IS MOVING SOUTH-SOUTHEASTWARD AT 06 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.5S 91.2E
IS NOW LOCATED NEAR 8.7S 91.6E, APPROXIMATELY 375 NM WEST-NORTHWEST
OF THE COCOS ISLANDS. RECENT ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS CONVECTION CONSOLIDATING ALONG THE SOUTHWESTERN PERI-
PHERY OF A WELL-DEFINED LOW LEVEL CIRCULATION CENTER ALSO EVIDENT
IN A 141109Z SSMI PASS. RECENT DVORAK T-NUMBERS FROM VARIOUS REPORT-
ING AGENCIES AND SATELLITE WIND-DERIVED INTENSITY ESTIMATES SUGGEST
THAT MAXIMUM SUSTAINED WIND SPEEDS HAVE INCREASED OVER THE PAST 06
TO 12 HOURS. THE DISTURBANCE LIES NEAR THE WESTERN PERIPHERY OF AN
EXTENSIVE UPPER LEVEL ANTICYCLONE, WITH MODERATE VERTICAL WIND SHEAR
AND FAVORABLE DIFFLUENCE ALOFT. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 28 TO 32 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1000 MB. DUE TO AN IMPROVING LOW LEVEL SIGNATURE, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
151630Z.
