98P is up. —The preceding unsigned comment was added by 24.83.98.3 (talk • contribs).

Shear is actually somewhat low in this area. If anything develops this early in their season, this might be it. Definitely looks like something's trying to get going down there. --Core des at talk. ^_^ 23:23, 2 August 2006 (UTC)[reply]

Yes it does. bob rulz 04:25, 3 August 2006 (UTC)[reply]

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 4.8S 63.2E,
IS NOW LOCATED NEAR 4.7S 62.4E, APPROXIMATELY 630 NM WEST-NORTHWEST
OF DIEGO GARCIA. RECENT ANIMATED INFRARED SATELLITE IMAGERY REVEALS
INCREASED CONVECTION IN THE VICINITY OF A LOW-LEVEL CIRCULATION
CENTER (LLCC), AND A 172251Z AMSU-B MICROWAVE SATELLITE PASS INDI-
CATES SEVERAL CLOUD BANDS BEGINNING TO WRAP INTO THIS LLCC. UPPER
LEVEL ANALYSIS CONTINUES TO DEPICT LOW TO MODERATE VERTICAL WIND
SHEAR ALOFT AND A VIGOROUS POLEWARD OUTFLOW CHANNEL. MAXIMUM SUS-
TAINED WINDS ARE ESTIMATED AT 25 TO 30 KTS. MINIMUM SEA LEVEL PRES-
SURE IS ESTIMATED TO BE NEAR 1007 MB. DUE TO INCREASED ORGANIZATION
OF THE CONVECTION ASSOCIATED WITH THIS DISTURBANCE, THE POTENTIAL
FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT
24 HOURS IS UPGRADED TO FAIR.

It is now explosively intensifying. --IrfanFaiz 03:37, 22 October 2006 (UTC)[reply]

An eye is clearly visible now. Hurricanehink (talk) 00:32, 23 October 2006 (UTC)[reply]

Shouldn't we start using hurricane infoboxes for Xavier? Also, the current track map shows it is moving towards Vanuatu. Maybe there should info included in the article about the latest Watches/Warnings. RaNdOm26 10:26, 23 October 2006 (UTC)[reply]

The current infobox doesn't accomodate Shem storms. I'll try to work on one in a sandbox. As far as I know, there are no warnings yet. – Ch acor 10:28, 23 October 2006 (UTC)[reply]

Tropical Depression 02F

Tropical Depression 02F [1004HPA] near 11S 176W moving west 10 knots.

Position poor and based on MTSAT IR/VIS animation. SST in the area is about 28C. 02F is embedded in an easterly trough and is currently being propagated westwards. Deep convection persists around the centre and at this stage there is a strong likelihood of multiple low level centres. 02F is located under the 250 hPa subtropical ridge in an area of strong diffluence. Environmental shear is minimal. Global models have picked up the system and steer it westwards but show reluctance in developing it. The potential for 02F to develop in a tropical cyclone is low to moderate in the next 24 to 48 hours.
