JTWC 07/18Z:
AN AREA OF CONVECTION HAS PERSISTED NEAR 4.3N 77.2E, APPROXIMATELY 220 NM SOUTHWEST OF COLUMBO, SRI LANKA. RECENT ANIMATED WATER VAPOR AND INFRARED SATELLITE IMAGERY SHOW DEEP CONVECTION FLARING NEAR THE CENTER OF A DEVELOPING LOW LEVEL CIRCULATION CENTER (LLCC) EVIDENT IN A 071225Z AMSU-B MICROWAVE IMAGE. THE DISTURBANCE LIES ON THE WESTERN PERIPHERY OF AN EXTENSIVE UPPER LEVEL RIDGE WITH MODERATE VERTICAL WIND SHEAR AND GOOD POLEWARD DIFFLUENCE. MAXIMUM SUSTAINED WINDS ARE ESIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS POOR. - SpLo T // 04:33, 8 April 2007 (UTC)[reply]
