B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION (INVEST 94W) HAS PERSISTED NEAR
21.4N 123.4E, APPROXIMATELY 240 NM SOUTH-SOUTHEAST OF TAIPEI,
TAIWAN. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS A
CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC) WITH DEVELOPING
CONVECTION TO THE SOUTH. A 310138Z AMSU 89GHZ MICROWAVE IMAGE SHOWS
WELL-DEFINED CLOUD LINES WRAPPING INTO THE LLCC. THE SYSTEM IS
LOCATED IN A FAVORABLE ENVIRONMENT WITH GOOD DIVERGENCE ALOFT AND
LOW (5-10 KNOT) VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES ARE
FAVORABLE FOR FURTHER DEVELOPMENT. GLOBAL MODELS INDICATE WEAK
DEVELOPMENT OF THIS DISTURBANCE IN THE NEXT 48 HOURS AS IT TRACKS
NORTH-NORTHEASTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1004 MB. DUE TO THE DEFINED LLCC AND FAVORABLE ENVIRONMENT, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS MEDIUM.
