TROPICAL DEPRESSION 1008 HPA AT 22N 139E NORTH SLOWLY.
----
(2) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 19.9N
132.6E, IS NOW LOCATED NEAR 21.3N 137.7E, APPROXIMATELY 285 NM
SOUTHWEST OF IWO TO, JAPAN. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A BETTER ORGANIZED LOW LEVEL CIRCULATION CENTER
WITH FLARING CONVECTION. A 130012Z ASCAT IMAGE DEPICTS 20 KNOTS
NEAR THE CENTER OF CIRCULATION. VERTICAL WIND SHEAR REMAINS LOW,
BUT AN UPPER LEVEL TROUGH AND CONVERGENT FLOW POLEWARD OF THE
DISTURBANCE HAS LIMITED DEVELOPMENT. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE NEAR 1006 MB. DUE TO IMPROVEMENT IN LOW LEVEL
ORGANIZATION AND MORE PERSISTENT CONVECTION, THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT
24 HOURS IS UPGRADED TO FAIR.
