JTWC 評級Low。
(1) THE AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR
7.6N 118.0E, APPROXIMATELY 119NM SOUTH-SOUTHWEST OF PUERTO
PRINCESA, PHILIPPINES.  THERE IS AN OBSCURED LOW LEVEL CIRCULATION
WITH SOME VISIBLE LOW LEVEL CLOUD LINES WRAPPING IN FROM THE EAST
AS SEEN IN THE FIRST FEW FRAMES OF VISIBLE IMAGERY.  ANALYSIS
INDICATES THE ENVIRONMENT IS FAVORABLE FOR TROPICAL CYCLONE
DEVELOPMENT WITH BURGEONING RADIAL OUTFLOW, WARM SEA SURFACE
TEMPERATURES (29-30 C), AND LOW (05-10 KTS) VERTICAL WIND SHEAR.
THERE IS HIGH UNCERTAINTY BETWEEN THE GLOBAL MODELS, WITH GFS
BEING THE BIGGEST PROPONENT FOR THE SYSTEMS DEVELOPMENT WITH 93W
REACHING STRONG TROPICAL STORM STRENGTH EAST OF THE VIETNAM
COASTLINE, WHILE ECMWF HARDLY RECOGNIZES A LOW LEVEL CIRCULATION
AND DOESN’T DEVELOP THE SYSTEM. ENSEMBLES HOWEVER HAVE A TIGHT
GROUPING FOR BOTH ECENS AND GEFS, AND BOTH PROPAGATE 93W TO
VIETNAM WITH MOST GEFS AND ECENS MEMBERS RECOGNIZING AT LEAST
A TROPICAL DEPRESSION STRENGTH SYSTEM. OVERALL ASSESSMENT IS
THAT 93W WILL CONTINUE TO MOVE WEST AND INTENSIFY IN THE
NEXT 36-48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 10 TO 15 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 LOW.

JTWC 平及提升"Medium"。
(1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 7.6N 118.0E IS NOW LOCATED NEAR 9.9N 116.2E, APPROXIMATELY
593NM SOUTHEAST OF DANANG, VIETNAM. THE POSITION FOR 93W WAS
RELOCATED BASED ON A 290211Z ASCAT-C IMAGE, WHICH SHOWS A
DEVELOPING, ELONGATED CIRCULATION ADJACENT TO A SWATH OF 20-25 KNOT
EASTERLIES OVER THE NORTHEAST QUADRANT WITH WEAKER WINDS (5-15
KNOTS) ELSEWHERE. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS
STRONG MID-LEVEL TURNING WITH LOW-LEVEL CLOUD LINES WRAPPING INTO
THE EASTERN QUADRANT SUGGESTING A DEVELOPING LOW-LEVEL CIRCULATION
CENTER (LLCC). A 282236Z SSMIS 91GHZ COLOR COMPOSITE MICROWAVE IMAGE
REVEALS A WEAKLY-DEFINED LLCC, HOWEVER, FORMATIVE DEEP CONVECTIVE
BANDS ARE EVIDENT OVER THE NORTHERN SEMICIRCLE. UPPER-LEVEL ANALYSIS
INDICATES NEAR-RADIAL OUTFLOW WITH LOW VERTICAL WIND SHEAR. SST
VALUES ARE CONDUCIVE FOR FURTHER DEVELOPMENT AT 29-30C. GFS REMAINS
THE MOST AGGRESSIVE MODEL WITH A TROPICAL DEPRESSION DEVELOPING
QUICKLY WITHIN THE NEXT TWO DAYS AS THE SYSTEM TRACKS NORTHWESTWARD
TOWARD VIETNAM. ECMWF AND NAVGEM SHOW A SIMILAR FORECAST TRACK BUT
WEAKER DEVELOPMENT. THE GFS SOLUTION APPEARS MORE LIKELY CONSIDERING
THE FAVORABLE ENVIRONMENTAL CONDITIONS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 12 TO 18 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 UPGRADED TO
MEDIUM.

JTWC評級升HIGH,發布TCFA
THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED  
NEAR 10.8N 114.3E IS NOW LOCATED NEAR 10.8N 113.2E, APPROXIMATELY  
407NM SOUTHEAST OF DANANG, VIETNAM. 93W HAS CONSOLIDATED OVER THE
LAST 12 HOURS WITH THE STRONG MID-LEVEL TURNING GRADUALLY BURROWING
DOWN TO THE SURFACE, THOUGH THE WEAK LOW LEVEL CIRCULATION (LLC)
REMAINS OBSCURED BY MID AND UPPER-LEVEL CLOUDS. ENVIRONMENTAL
ANALYSIS INDICATES PRIME CONDITIONS FOR DEVELOPMENT WITH NEAR-RADIAL
OUTFLOW WITH LOW (05-10KT) VERTICAL WIND SHEAR AND WARM (29-30C) SEA
SURFACE TEMPERATURES. THE MAIN HINDRANCES AT THE MOMENT ARE THE
RELATIVELY SHORT TIME REMAINING OVER WATER AND THE RELATIVELY SLOW
CONSOLIDATION OF THE LLC. GFS REMAINS THE MOST AGGRESSIVE MODEL WITH
A TROPICAL DEPRESSION DEVELOPING QUICKLY WITHIN THE NEXT 18-36 HOURS
AS THE SYSTEM TRACKS NORTHWESTWARD TOWARD VIETNAM. ECMWF AND NAVGEM
SHOW A SIMILAR TRACK BUT WITH SIGNIFICANTLY LESS DEVELOPMENT. THE
GFS SOLUTION APPEARS MORE LIKELY CONSIDERING THE FAVORABLE
ENVIRONMENTAL CONDITIONS. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 12 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
HIGH. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23
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 HIGH.
