JTWC: 0300am UTC - グリフオーザー 05:17, 16 December 2006 (UTC)[reply]
An area of convection persistent near 7.2ºS 68.0ºE or 250 nm west of Diego Garcia. Imagery shows a sustained convection in the vicinity of the low level circulation center. Analysis reveals that the disturbance is within a region of low vertical wind shear with maximum sustained winds of 15 to 20 knots and a center pressure of 1006 mb.

The potential of this disturbance to develop into a significant tropical cyclone within 24 hours is poor.

TCFA issued, upgraded to GOOD. 9.1S 65.8E, 410 nm WSW of Diego Garcia. Deep convection flaring over LLCC with convective bands. Low vertical wind shear, strong poleward outflow with good divergence aloft. Winds of 25 to 30 kt, pressure of 1002 mb. - SpLo T _{(*T* C+u+g+v)} 02:50, 17 December 2006 (UTC)[reply]

no advisories from RSMC La Reunion, probably at 630am UTC. - グリフオーザー 03:10, 17 December 2006 (UTC)[reply]

2.B OTHER INFORMATIONS: T=CI=5.0+. THE SYSTEM "BONDO" HAS RAPIDELY INTENSIFYED LAST NIGTH, WITH A BIULDING EYE THIS MORNING (CF IMAGE WINDSAT 0154Z). DUE TO ETABLISHMENT OF A SECOND OUTFLOW CHANEL EQUATORWARDS, AND A MOONSON FLOW BECOMING MORE DIRECT. SYSTEM INTENSITY HAS BEEN REANALYSED from 18 at 18utc, AND dVORAK RULES BROKEN IT REMAINS WITHIN A FAVOURABLE ENVIRONMENT AND IS EXPECTED TO KEEP ON TRACKING GENERALLY WESTWARDS, INTENSIFYING, THEN SOUTHWESTWRADS AT THE END OF FORCAST.

Rapid intensification! Now 85 kt, 950 hPa. – Ch acor 12:21, 19 December 2006 (UTC)[reply]

JTWC has upped it to a Cat 3. 105 kt, 938 mb, and predicted to become a Cat 4 125kt in 12 hours and a Cat 5 140kt in 24 hours. – Ch acor 15:10, 19 December 2006 (UTC)[reply]

Now unofficially 130kt/910mb (NRL). It's going to be a close call with the northern tip of Madagascar. Pobbie Rarr 19:32, 19 December 2006 (UTC)[reply]

110 knots 915 hpa (10 min avg) wonder if this strengthening will continue to upgrade to very intense tropical cyclone. - グリフオーザー 01:14, 20 December 2006 (UTC)[reply]

AT 10H00 THIS MORNING TROPICAL CYCLONE BONDO WAS CENTRED AROUND 10.4'S AND 55.1 'E, ABOUT 140 KM TO THE WEST OF AGALEGA. IT IS MOVING IN A GENERAL WESTERLY DIRECTION AT 18 KM/H.

Surprisingly, Mauritius used just two sentence to talk about Bondo in their weather forecast and did not issue any warning. Though the 10-minute wind speed was just 25kt at Agalega, I think they should emphasize the cyclone more. If Bondo was 40km closer to Agalega, the situation would be terrible.Momoko 08:54, 20 December 2006 (UTC)[reply]

I think the reason for that is because it's almost out of their area into Madagascar's, at 55E. – Ch acor 10:06, 20 December 2006 (UTC)[reply]

JTWC 9am UTC: - グリフオーザー 18:08, 24 December 2006 (UTC)[reply]
Area of persistent convection near 5.5ºS 66.4ºE or 380 nm west-northwest of Diego Garcia. Imagery shows banding beginning to wrap into western quadrant of a developing low level circulation center. Analysis shows this disturbance is within moderate to low vertical wind shear with sustained winds of 20 to 25 knots and a center pressure of 1004 mb.

The potential of development into a tropical cyclone is poor

Looking good now. JTWC upgraded to fair. --Core desat 00:03, 25 December 2006 (UTC)[reply]

Mauritius marine bulletin has this as a tropical disturbance, nothing from La Reunion yet. --Core desat 01:41, 25 December 2006 (UTC)[reply]

Zone Perturbée (04-20062007)

Now an "zone of disturbed weather" from RSMC La Réunion, but "CONVECTION DOES NOT SHOW ANY ORGANIZATION" and "LLCC APPEARS NORTH-EAST OF THE CONVECTION." – Ch acor 12:58, 25 December 2006 (UTC)[reply]

Perturbation Tropicale

now designed as a tropical disturbance by La Reunion RSMC. - グリフオーザー 17:15, 26 December 2006 (UTC)[reply]

TCFA. --Core desat 00:14, 27 December 2006 (UTC)[reply]

Zone Perturbée (05-20062007)

M-F just introduced Zone of disturbed weather 05. Its co-ordinates are pretty near 90S, and they've killed 04R off. Is 90S = 05R? – Ch acor 13:23, 29 December 2006 (UTC)[reply]

Since this is still being monitored as 90S, I've moved this section to the 90S.PT section and renumbered it to 05R. It's the same area of convection, but its LLCC dissipated, so it's being monitored as a new system (as you stated in IRC). --Core desat 02:37, 30 December 2006 (UTC)[reply]

I smell an error, the NRL imagery only shows a cold front here, and the models don't pick up on anything in this area. --Core desat 06:19, 23 December 2006 (UTC)[reply]

Yep, it was a position error. Relocated to 17.0S 165.1W. Strange error, indeed. --Core desat 07:54, 23 December 2006 (UTC)[reply]

Tropical Low (*93S)

10.0ºS 113.0ºE -- 1006 hPa

REMARKS - There has been increasing thunderstorm activity over and to the south of Indonesia and there are indications the weak tropical low as above could develop in this area. Most likely movement of the low is towards the south-southeast.

There is the possibility that the low or cyclone could be near the Pilbara coast by Wednesday. —The preceding unsigned comment was added by VOFFA (talk • contribs) 04:42, 29 December 2006 (UTC).[reply]

renamed as 95S which is at 12.9S 113.7E -- グリフオーザー 18:44, 30 December 2006 (UTC)[reply]

I think it's now on NRL. Position is iffy, but close. 9.5S, 106E, 15kt, 1006mb. -- RattleMan 09:50, 29 December 2006 (UTC)[reply]

This looks interesting. BoM predicts a HIGH potential of cyclone development on Tuesday, and a cyclone impact on Wednesday. RaNdOm26 08:33, 30 December 2006 (UTC)[reply]

They just keep coming. 12.9S 113.7E, 15kt. -- RattleMan 17:27, 30 December 2006 (UTC)[reply]

High probability of development in the next 48 hours, according to BoM. --Core desat 04:35, 31 December 2006 (UTC)[reply]

Umm, what happened to 93S.INVEST? Did it dissipate? Anyway, now, BoM calls for the low to develop to a cyclone within 24 hours. RaNdOm26 08:36, 31 December 2006 (UTC)[reply]

Intensity increased to 25 knots and pressure of 1004 hPa from BoM. RaNdOm26 08:44, 31 December 2006 (UTC)[reply]

pressure down to 1002 hPa -- グリフオーザー 19:08, 31 December 2006 (UTC)[reply]

Tropical Low

Advisories now issued from BOM -- グリフオーザー 01:38, 1 January 2007 (UTC)[reply]

This low is threatening for a landfall near Port Hedland as a Category 3. Cool graphics! RaNdOm26 09:17, 1 January 2007 (UTC)[reply]

The only reason I think this is down as system 1 is it is in the only system they are currently warning about. As far as I know it won't actually get a number unless it reaches TC strength in which case this would become 200601. --P.K. 13:03, 1 January 2007 (UTC)

TCFA. And indeed, I'm removing the number from the talk subheader since tropical lows aren't numbered, unless the TCOP says otherwise. --Core desat 03:02, 2 January 2007 (UTC)[reply]

None of the lows are numbered in any way from BOM, I think..... Isobel is now moving very quickly southwards. RaNdOm26 07:44, 2 January 2007 (UTC)[reply]
