JTWC IS ISSUING 3HOURLY SATELLITE BULLETINS ON 93S.
SOUTHERN HEMISPHERE/SOUTH INDIAN OCEAN: INVEST 93S. DOWN-GRADED TO LOW AT 31/0930UTC
THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED NEAR 12.1S 82.6E IS NOW LOCATED NEAR 13.1S 80.2E, APPROXIMATELY 1065 KM SOUTHEAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY AND A 310802Z AMSR2 89GHZ IMAGE REVEAL A BROAD LOW LEVEL CIRCULATION CENTER (LLCC) DEFINED BY WELL-DEFINED, BUT SHALLOW BANDING WITH VERY WEAK CONVECTION SHEARED TO THE SOUTHWEST. ENVIRONMENTAL ANALYSIS INDICATES AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH HIGH (25-30 KNOTS) NORTHEAST VERTICAL WIND SHEAR AND MARGINAL SEA SURFACE TEMPERATURES (26C) OFFSET BY GOOD POLEWARD OUTFLOW. ADDITIONALLY, THERE IS SIGNIFICANT DRY AIR ENTRAINMENT THROUGHOUT THE MID-LEVELS THAT IS HINDERING CONVECTIVE DEVELOPMENT. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT THE CIRCULATION ASSOCIATED WITH INVEST 93S WILL CONTINUE TO TRACK WESTWARD, BUT IT IS NOT EXPECTED TO DEVELOP AT THIS TIME. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 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 DOWNGRADED TO LOW.
