JTWC : MEDIUM
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.0N
145.0E, IS NOW LOCATED NEAR 9.0N 141.4E, APPROXIMATELY 190 NM EAST
OF YAP ISLAND. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A
CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC) WITH AN AREA OF
LINEAR DEEP CONVECTION SHEARED TO THE NORTH OF THE SYSTEM. A 282359Z
AMSU-B IMAGE REVEALS THE POSITION OF THE CONSOLIDATING LLCC AS WELL
AS DEEP CONVECTIVE BANDING TO THE NORTH. RECENT SCATTEROMTERY PASSES
HAVE INDICATED A BROAD CIRCULATION WITH WEAK CORE WINDS AND 15 TO 20
KNOT NORTHEASTERLY SURGE WINDS OVER THE NORTHERN SEMICIRCLE AND
WESTERN QUADRANT. UPPER-LEVEL ANALYSIS SHOWS A MARGINAL ENVIRONMENT
WITH A LIMITED AREA OF WEAK TO MODERATE (10 TO 20 KNOTS) VERTICAL
WIND SHEAR AND STRONG DIFFLUENCE ALOFT. DYNAMIC MODELS INDICATE THE
DEVELOPMENT OF A WEAK TC WITHIN THE NEXT 48-60 HOURS. 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 UPGRADED TO MEDIUM. |
