JTWC 05Z評級LOW,未來將進入孟加拉灣發展。
(1) AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR 4.8N
104.0E, APPROXIMATELY 213 NM NORTH OF SINGAPORE. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS A SLOWLY DEVELOPING LOW-
LEVEL CIRCULATION CENTER (LLCC) WITH DISORGANIZED DEEP CONVECTION
FLARING OVER THE NORTHERN SEMI-CIRCLE. A 290213Z METOP-A 89GHZ IMAGE
REVEALS A POORLY-ORGANIZED LLCC WITH WEAK BANDING. A 290212Z ASCAT
IMAGE SHOWS A DEFINED BUT WEAK CIRCULATION WITH 10 KNOT WINDS NEAR
THE CENTER AND 20 TO 30 KNOT NORTHEASTERLY WINDS DISPLACED TO THE
NORTH. UPPER-LEVEL ANALYSIS INDICATES A MARGINAL ENVIRONMENT WITH
MODERATE VERTICAL WIND SHEAR AND BROAD EASTERLY DIFFLUENT FLOW.
GLOBAL DYNAMIC MODELS INDICATE A WEST-NORTHWESTWARD TRACK ACROSS THE
MALAY PENINSULA INTO THE BAY OF BENGAL WITH SIGNIFICANT DEVELOPMENT
AFTER THE SYSTEM RE-EMERGES OVER WATER NEAR TAU 48 TO 72. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.

JTWC 21Z 評級提升至Medium,進入孟灣整合發展中。
(1) AN AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR
4.8N 104.0E IS NOW LOCATED WEST OF 100E AND IS BEING DISCUSSED ON
THE SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN. SEE
REF A (ABIO10 PGTW 292230) FOR FURTHER DETAILS.
(2) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 4.8N 104.0E, IS NOW LOCATED NEAR 6.7N 100.3E, APPROXIMATELY 388
NM NORTHWEST OF SINGAPORE. ANIMATED ENHANCED INFRARED IMAGERY SHOWS
PERSISTENT DEEP CONVECTION OBSCURING A CONSOLIDATING LOW LEVEL
CIRCULATION. 93W IS BENEFITTING FROM WESTWARD AND POLEWARD OUTFLOW
WITH MODERATE TO HIGH (20-25 KNOT) VERTICAL WIND SHEAR (VWS) THAT IS
EXPECTED TO DECREASE IN THE FUTURE. SEA SURFACE TEMPERATURES ARE
WARM (28-29 CELSIUS) AND WILL SUPPORT FURTHER DEVELOPMENT. GLOBAL
DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT, PREDICTING DEVELOPMENT
ONCE 93W REACHES THE WARM WATERS OF THE ANDAMAN SEA ON ITS WESTWARD
TRACK ACROSS THE BAY OF BENGAL. THE POSSIBILITY EXISTS FOR
DEVELOPMENT TO BE DELAYED SHOULD 93W TRACK OVER SUMATRA. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

JTWC 17Z降評至LOW
(1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 5.7N 97.8E, IS NOW LOCATED NEAR 4.9N 94.4E, APPROXIMATELY 626
NM WEST-NORTHWEST OF SINGAPORE. ANIMATED ENHANCED INFRARED IMAGERY
AND A PARTIAL 021534Z METOP-B AMSU 89GHZ IMAGE DEPICT SCATTERED
CONVECTION ON BOTH THE NORTHERN AND WESTERN PERIPHERY OF THE LOW
LEVEL CIRCULATION (LLC). A 021535Z METOP-A ASCAT PASS REVEALS
SEVERAL 15-20 KNOT WIND BARBS IN THE SOUTHWESTERN PERIPHERY OF THE
LLC. UPPER LEVEL ANALYSIS INDICATES 93W IS LOCATED IN AN AREA OF
LIGHT TO MODERATE (10-15 KNOTS) VERTICAL WIND SHEAR (VWS), WITH WEAK
DIFFLUENCE ALOFT. WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURES WILL
ASSIST THE SYSTEMS DEVELOPMENT AS IT TRANSITS TO THE NORTHWEST.
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 93W WILL DEVELOP OVER THE
NEXT 72 TO 96 HOURS ONCE IN OPEN WATER. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED
TO LOW.

評級再次提升至Medium
(1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 5.5N 91.7E IS NOW LOCATED NEAR 9.9N 88.5E, APPROXIMATELY 560
NM SOUTHEAST OF VISAKHAPATNAM, INDIA. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A MONSOON DEPRESSION WITH A BROAD LOW
LEVEL CIRCULATION CENTER (LLCC) AND CONVECTION LOCATED AROUND THE
PERIPHERY, BUT SPARSE NEAR THE CENTER. A 060431Z GMI 89GHZ PARTIAL
MICROWAVE IMAGE CONFIRMS AN ELONGATED LLCC WITH FORMATIVE BUT
FRAGMENTED CONVECTIVE BANDING OVER THE NORTHERN SEMI-CIRCLE. A
060308Z ASCAT PASS SHOWS 5-10 KT CORE WINDS WITH STRONGER 20-25 KT
WINDS ON THE DISTURBANCE'S PERIPHERY. THE SYSTEM IS CURRENTLY
LOCATED IN A FAVORABLE ENVIRONMENT WITH A POLEWARD OUTFLOW CHANNEL,
LEADING TO STRONG DIVERGENCE ALOFT, LOW VERTICAL WIND SHEAR VALUES
(10-15 KNOTS), AND WARM (28-29 CELSIUS) SEA SURFACE TEMPERATURES.
GLOBAL MODELS INDICATE THAT 93W WILL SLOWLY STRENGTHEN WHILE
TRACKING NORTH TO NORTHWESTWARD IN THE NEXT SEVERAL DAYS. 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 UPGRADED TO MEDIUM.
