還沒死,回到Medium。 ABIO10 PGTW 140200 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN /REISSUED/140200Z-141800ZJUN2015// RMKS/ 1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 20.7N 59.9E, IS NOW LOCATED NEAR 20.6N 59.6E, APPROXIMATELY 35 NM EAST OF MASIRAH ISLAND, OMAN. ANIMATED INFRARED SATELLITE IMAGERY INDICATES A LINE OF PERSISTENT DEEP CONVECTION TO THE SOUTH-SOUTHWEST OF THE REMNANTS OF 01A HAS GRADUALLY MOVED CLOSER TO THE ILL-DEFINED LOW LEVEL CIRCULATION CENTER (LLCC). RECENT MICROWAVE IMAGERY, INCLUDING A 132122Z AMSR 36 GHZ PASS, HAS REVEALED A GENERALLY DISORGANIZED LLCC WITH MOSTLY LINEAR DEEP CONVECTION. UPPER LEVEL ANALYSIS INDICATES A HOSTILE ENVIRONMENT WITH STRONG (20 TO 30 KNOTS) VERTICAL WIND SHEAR. SURFACE WINDS ALONG THE SOUTHERN PERIPHERY ARE BEING ENHANCED BY SOUTHWESTERLY WINDS ASSOCIATED WITH THE LOW LEVEL SOMALI JET. DYNAMIC GUIDANCE GENERALLY SHOWS AN ERRATIC, SLOW TRACK MOTION WITH A FORECAST WEAKENING TREND. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. DUE TO INCREASINGLY PERSISTENT NATURE OF THE DEEP CONVECTION AND ITS PROXIMITY TO THE REMNANT LLCC,THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM. (2) NO OTHER SUSPECT AREAS. 2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: NONE. 3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO MEDIUM// NNNN |

已命名Ashobaa,目前主流機構都預測進入阿曼灣。 The deep depression over eastcentral Arabian Sea has moved north-northwestwards during past 6 hours and intensified further into a cyclonic storm (ASHOBAA), and lay centred at 0830 hours IST of 08th June 2015 near latitude 17.90 N and longitude 67.20 E, about 590 km west- southwest of Mumbai, 470 km southwest of Veraval and 960 km east-southeast of Masirah Island (Oman). It would move initially north-northwestwards and intensify further into a severe cyclonic storm during next 36 hours. |
