JTWC21/1800Z評級Low
(2) AN AREA OF CONVECTION (INVEST 95S) HAS PERSISTED NEAR
20.2S 42.6E, APPROXIMATELY 126 NM EAST-NORTHEAST OF EUROPA ISLAND.
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 211553Z 91GHZ
SSMIS MICROWAVE IMAGE SHOW MINIMAL CONVECTION LOCATED OVER THE LOW
LEVEL CIRCULATION (LLC). HOWEVER, A 210523Z ASCAT IMAGE DEPICTS AN
ELONGATED CIRCULATION WITH 25-30KT WINDS OVER THE SOUTHWEST
QUADRANT. INVEST 94S IS CURRENTLY IN A FAVORABLE ENVIRONMENT FOR
DEVELOPMENT WITH EQUATORWARD AND EASTWARD OUTFLOW, LOW (<15 KNOTS)
VERTICAL WIND SHEAR, AND WARM (30-31C) SEA SURFACE TEMPERATURES.
GLOBAL MODELS ARE IN AGREEMENT THAT 95S WILL TRACK SLOWLY EASTWARD
WITH SLIGHT INTENSIFICATION. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 15 TO 20 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 LOW.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
140 NM EITHER SIDE OF A LINE FROM 18.2S 50.0E TO 20.2S 58.5E WITHIN
THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF
NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA
ARE ESTIMATED TO BE 28 TO 33 KNOTS. METSAT IMAGERY AT 231800Z
INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 18.2S 50.3E. THE

CIRCULATION (LLC). A 231713Z METOP-A ASCAT PASS REVEALS A TIGHT LLC
WITH 30 KT WIND BARBS NEAR THE CENTER. INVEST 95S IS CURRENTLY IN A
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH MODERATE (10-20KTS)

REMARKS:
242100Z POSITION NEAR 19.9S 57.7E.
24JAN20. TROPICAL CYCLONE (TC) 10S (DIANE), LOCATED APPROXIMATELY 38
NM NORTHWEST OF PORT LOUIS, MAURITIUS, HAS TRACKED EAST-
SOUTHEASTWARD AT 15 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS A CONSOLIDATING LOW-LEVEL
CIRCULATION WITH PERSISTENT DEEP CONVECTION. A 241805Z AMSU 89GHZ
MICROWAVE IMAGE INDICATES IMPROVED CURVED DEEP CONVECTIVE BANDING
OVER THE WESTERN SEMICIRCLE WRAPPING INTO THE NORTHERN QUADRANT OF A
DEFINED, EXPOSED LOW-LEVEL CIRCULATION CENTER. A 241652Z ASCAT
BULLSEYE DEPICTS A WELL-DEFINED CIRCULATION WITH 35-40 KNOT WINDS
OVER THE NORTHERN SEMICIRCLE. OVERALL CONFIDENCE IN THE INITIAL
POSITION AND INTENSITY IS GOOD BASED ON THE TIMELY ASCAT DATA.
ENVIRONMENTAL ANALYSIS INDICATES A MARGINALLY-FAVORABLE
ENVIRONMENT WITH STRONG (25-30 KNOTS) EASTERLY VERTICAL WIND SHEAR
(VWS) OFFSET BY GOOD EQUATORWARD AND POLEWARD OUTFLOW. SST VALUES OF
28-29C ARE CONDUCIVE FOR FURTHER DEVELOPMENT. TC 10S IS TRACKING
ALONG THE SOUTHERN PERIPHERY OF THE NEAR-EQUATORIAL RIDGE POSITIONED
TO THE NORTH AND IS FORECAST TO CONTINUE TRACKING EAST-SOUTHEASTWARD
THROUGH TAU 48. SLIGHT INTENSIFICATION IS EXPECTED AS VWS DECREASES
WITH A PEAK OF 45 KNOTS BY TAU 24. AFTER TAU 48, THE SYSTEM SHOULD
SLOW AND GRADUALLY TURN SOUTHEASTWARD AS THE STEERING ENVIRONMENT
WEAKENS DUE TO THE PRESENCE OF TC 11S. THE SYSTEM SHOULD WEAKEN DUE
TO INCREASING VWS ASSOCIATED WITH AN APPROACHING BROAD UPPER-LEVEL
SHORTWAVE TROUGH. AFTER TAU 72, TC 10S WILL TRACK SOUTHWARD AS THE
LOW-LEVEL SUBTROPICAL RIDGE BUILDS TO THE EAST AND SOUTH AND IS
FORECAST TO DISSIPATE UNDER COOLER SST AND STRONG VWS (30-40 KNOTS).
TC 10S IS FORECAST TO APPROACH WITHIN 320NM OF TC 11S AT TAU 96 AND
WILL LIKELY INFLUENCE ITS TRACK. OVERALL, CONFIDENCE IS LOW DUE TO
THE COMPLEX, EVOLVING STEERING ENVIRONMENT. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 241800Z IS 12 FEET. NEXT WARNINGS AT 250900Z AND 252100Z.
REFER TO TROPICAL CYCLONE 11S (ELEVEN) WARNINGS (WTXS32 PGTW) FOR
TWELVE-HOURLY UPDATES.
