RSMC / TROPICAL CYCLONE CENTRE / LA REUNION TROPICAL CYCLONE FORECAST WARNING (SOUTH-WEST INDIAN OCEAN) 0.A WARNING NUMBER : 30/8/20072008 1.A TROPICAL DEPRESSION 8 (EX-FAME) 2.A POSITION 2008/02/01 AT 0000 UTC : 21.6S / 54.8E (TWENTY ONE DECIMAL SIX DEGREES SOUTH AND FIFTY FOUR DECIMAL EIGHT DEGREES EAST) 3.A DVORAK ANALYSIS : /W 4.A CENTRAL PRESSURE : 990 HPA 5.A MAX AVERAGE WIND SPEED (10 MN) : 30 KT 6.A EXTENSION OF WINDS BY QUADRANTS (KM): 30 KT NE: 130 SE: SO: 350 NO: 180 7.A FIRST CLOSED ISOBARE (PRESSURE / AVERAGE DIAM): 1002 HPA 8.A VERTICAL EXTENSION OF CYCLONE CIRCULATION: MEDIUM 1.B FORECASTS: 12H: 2008/02/01 12 UTC: 24.1S/59.1E, MAX WIND=030KT, DISSIPATING. 24H: 2008/02/02 00 UTC: 29.0S/61.0E, MAX WIND=025KT, DISSIPATING. 36H: 2008/02/02 12 UTC: DISSIPATED. 2.B OTHER INFORMATIONS: DVORAK CLASSIFICATION IS NOT SIGNIFICANT. THIS SYSTEM IS A RESIDUAL VORTEX WHOTHOUT ANY CONVECTIVE ACTIVITY, WHICH GENERATES A BELT OF STRONG WINDS MAINLY IN THE NORTHERN SEMI-CIRCLE DUE TO ITS ADDED OWN SPEED MOTION EASTWARDS (NEAR 20KT). IT IS TRANSITING JUST SOUTH OF REUNION ISLAND WHICH IS SUBMITED TO STRONG WINDS DURING THIS ENDING NIGHT, DUE TO THE FACT THAT THE ISLAND IS LOCATED EXACTLY WITHIN THE STRONGEST WINDS BELT. MINIMAL SEA LEVEL PRESSURE IS LOWER THAN FOR A TYPICAL TROPICAL DEPRESSION (ESTIMATED ACCORDING TO OBSERVATION DATA). THE SYSTEM IS MAKING A LOOP TOWARDS THE TROPICAL STORM GULA, WHICH IS TRACKING QUIKCLY SOUTHWARDS. IT SHOULD EVACUATE SOUTHWARDS RAPIDLY AND DISSIPATE IN THE TROUGH OF GULA.
