JTWC於12070800Z評級Low。有部分模式指出,此系統在原地短期滯留後,將逐漸北上趨近印度東岸。
AN AREA OF CONVECTION (INVEST 94B) HAS PERSISTED NEAR 4.3N
87.4E, APPROXIMATELY 475 NM EAST-SOUTHEAST OF COLOMBO, SRI LANKA.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 070326Z MHS 89GHZ
MICROWAVE IMAGE DEPICT A BROAD LOW LEVEL CIRCULATION WITH CONVECTION
SHEARED TO THE WEST. A 061554Z ASCAT PARTIAL PASS SHOWS AN ELONGATED
CIRCULATION WITH PRIMARILY 15-20 KNOT WINDS NEAR THE CENTER AND A
SMALL AREA OF 25 KNOT WINDS TO THE EAST. THE SYSTEM IS CURRENTLY
LOCATED IN AN AREA OF GOOD POLEWARD UPPER LEVEL OUTFLOW, MODERATE TO
HIGH VERTICAL WIND SHEAR (20-25), AND WARM SEA SURFACE TEMPERATURES
(29-30 CELSIUS). GLOBAL MODELS ARE IN AGREEMENT THAT THE SYSTEM,
AFTER A BRIEF PERIOD OF QUASI-STATIONARY MOVEMENT, WILL TRACK TO THE
NORTH AND INTENSIFY TO WARNING CRITERIA WITHIN THE NEXT SEVERAL
DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.
