JTWC 06z評級提升Medium。(1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED
NEAR 10.3N 136.9E IS NOW LOCATED NEAR 10.7N 134.2E, APPROXIMATELY
190 NM NORTH OF PALAU. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY AND A 230115Z MHS METOP-B 89GHZ
MICROWAVE IMAGE DEPICT SCATTERED CONVECTION BEGINNING TO WRAP INTO
AN EXPOSED, SLOWLY CONSOLIDATING LOW LEVEL CIRCULATION (LLC). 98W IS
CURRENTLY IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH GOOD
WESTWARD UPPER LEVEL OUTFLOW, LOW (<15 KNOTS) VERTICAL WIND SHEAR,
AND VERY WARM (30 TO 31 CELSIUS) SEA SURFACE TEMPERATURES. GLOBAL
MODELS ARE IN GENERAL AGREEMENT THAT 98W WILL TRACK GENERALLY
NORTHWESTWARD WITH ONLY SLIGHT INTENSIFICATION OVER THE NEXT 24
HOURS, BUT INDICATE AN INCREASE IN INTENSIFICATION BEYOND 24 HOURS
WITH A WESTWARD TRACK TOWARD THE PHILIPPINES. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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 MEDIUM.
