14.8S 117.5E 15 kt, west of 92S. – Chacor 15:19, 2 March 2007 (UTC)

JTWC 030800: AN AREA OF CONVECTION HAS PERSISTED NEAR 13.9S 117.1 E, APPROXIMATELY 395 NM NORTH-NORTHWEST OF PORT HEDLAND, AUSTRALIA. RECENT ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS CONVECTION PER- SISTING OVER A TIGHT LOW LEVEL CIRCULATION CENTER ALSO EVIDENT IN A 020549Z AMSU-B MICROWAVE IMAGE. THIS DISTURBANCE IS NORTH OF THE NEAR- EQUATORIAL UPPER LEVEL RIDGE AXIS IN AN ZONE OF FAVORABLE DIFFLUENCE ALOFT BUT MODERATE VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTI- MATED TO BE NEAR 1004 MB. DUE TO UNFAVORABLY HIGH VERTICAL WIND SHEAR, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS POOR. -  SpL o T  // 09:31, 3 March 2007 (UTC)

Perth TCWC - Tropical Low
Tropical Low 14.3ºS 114.8ºE -- 1000 hPa

730 km north northwest of Karratha moving west-northwest at 4 knots.

Tropical Cyclone Jacob
12.8ºS 108.3ºE -- 45 knots 988 hPa Cyclone Watch for Christmas Island - グリフオーザー 01:24, 7 March 2007 (UTC)

 * Up to 55 kt from the TCWC, cyclone warning for Christmas Island. --Core desat  07:54, 7 March 2007 (UTC)

Severe Tropical Cyclone Jacob
70 knots 956 hPa, Cyclone Warning continues for Christmas Is. - グリフオーザー 22:53, 7 March 2007 (UTC)

Set to make landfall close to where George hit, weakened due to supressed poleward outflow and high vertical wind shear. -  SpL o T  // 15:20, 10 March 2007 (UTC)

Getting more organized, POOR from JTWC 09/18Z. -  SpL o T  // 03:02, 10 March 2007 (UTC)

JTWC 10/1230Z:  THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.8S 65.0E, IS NOW LOCATED NEAR 15.0S 62.0E, APPROXIMATELY 770 NM SOUTHWEST OF DIEGO GARCIA. RECENT ANIMATED MULTISPECTRAL SAT- ELLITE IMAGERY AND A 100942Z AMSU-B MICROWAVE IMAGE DEPICT AN IMPROVING LOW LEVEL CIRCULATION CENTER (LLCC) WITH CONVECTION FLARING NEAR AND OVER THE CENTER. UPPER LEVEL ANALYSIS INDICATES THAT THIS DISTURBANCE LIES UNDER THE DIFFLUENT REGION OF A 200 MB ANTICYCLONE, WITH LOW VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. BECAUSE THE LLCC HAS IMPROVED AND CONVECTION IS FLARING NEAR THE CENTER, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO FAIR. -  SpL o T  // 15:22, 10 March 2007 (UTC)

 * JTWC TC 19S Indlala. I've emailed Meteo France for clarification, since they're now calling it "Indlala" too but the map says "Indlada" and SAB says "Indlada". – Chacor 03:45, 12 March 2007 (UTC)

 * There seems to be some confusion: -- RattleMan 04:09, 12 March 2007 (UTC)

MetFrance have replied (about 30 hours after I sent the email! Heh) - the correct name is "Indlala", with an "l". – Chacor 08:44, 13 March 2007 (UTC)

 * 12F? The last one we have is 09F. Where'd 10F and 11F go? – Chacor 02:13, 22 March 2007 (UTC)
 * I think we should hold off on adding it to the article for now, until this is cleared up (Core is emailing Nadi). – Chacor 02:17, 22 March 2007 (UTC)
 * Was wondering the same thing, unless they numbered Odette and another Tropical Low from Brisbane that entered their area. - グリフオーザー 02:34, 22 March 2007 (UTC)
 * Email reply from RSMC Nadi: "Just to let you know that 10F and 11F were short-lived systems and may therefore not gained much attention. The numbering is therefore in order." --Core desat  04:26, 22 March 2007 (UTC)
 * I can't find tropical disturbance summaries that mention 10F and 11F - Chacor e-mailed Gary Padgett, who might know more. I'm personally going to hold off on adding 12F for a little bit until we figure this out, but someone else can add it if they want. --Core desat  04:39, 22 March 2007 (UTC)

Upper level analysis shows an anticyclone east of the center with diffluent easterly flow over the area with weak vertical wind shear. Maximum sustained winds of 15 to 20 knots with a sea level pressure estimated at 1005 mb. The potential of this disturbance to develop into a significant tropical cyclone is poor.

JTWC: 930am UTC: An area of convection near 14.3S 42.0E or 405 nm west-northwest of Antananarivo, Madagascar. The remnants of Jaya is beginning to re-organize in the Mozambique Channel. Imagery shows increased deep convection over the low level circulation center with 20 to 25 knots unflagged winds close to the center. The system is less than 100 nm from the Mozambique coastline, but it may strengthen into a tropical cyclone prior to landfall. Maximum sustained winds are estimated at 20 to 30 knots with a center pressure of 1002 mb The potential of this disturbance to develop into a significant tropical cyclone is GOOD. - グリフオーザー 09:45, 5 April 2007 (UTC)
