B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION (INVEST 91W) HAS PERSISTED NEAR
19.7N 128E, APPROXIMATELY 480 NM SOUTHEAST OF TAIPEI, TAIWAN.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS AN ELONGATED
CIRCULATION WITH FLARING CONVECTION LOCATED ON THE PERIPHERY OF THE
DISTURBANCE. A 050627Z AMSU-B 89GHZ MICROWAVE IMAGE SHOWS MINIMAL
CONVECTION WITH A POORLY DEFINED ELONGATED CIRCULATION. THE
DISTURBANCE IS CURRENTLY LOCATED IN A FAVORABLE ENVIRONMENT WITH
GOOD DIVERGENCE ALOFT, LOW VERTICAL WIND SHEAR (5-10 KTS), AND VERY
HIGH SEA SURFACE TEMPERATURES (30-31 C). GLOBAL MODELS ARE CURRENTLY
NOT INITIALIZING WITH A CIRCULATION IN THE AREA OR DEVELOPING THE
SYSTEM HOWEVER, THE DISTURBANCE HAS BEEN TRACKING TO THE WEST-
NORTHWEST OVER THE PAST FEW DAYS. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1010 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
