B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 94W) HAS PERSISTED NEAR 12N
118.3E, APPROXIMATELY 221 NM SOUTHWEST OF MANILA, PHILIPPINES .
ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD LOW LEVEL
CIRCULATION CENTER (LLCC) WITH CONVECTION WRAPPING IN FROM THE SOUTH
WESTERN PERIPHERY. A 170201Z 89GHZ AMSU AND METOP-A ASCAT IMAGE
SHOWS AN ELONGATED AND DISORGANIZED CIRCULATION CENTER WITH
SCATTERED CONVECTION THROUGHOUT THE SOUTH WESTERN PORTION OF THE
DISTURBANCE. THE UPPER LEVEL ANALYSIS SHOWS THAT THE DISTURBANCE IS
CURRENTLY LOCATED IN AN AREA OF GOOD UPPER LEVEL DIVERGENCE,
LOW TO MODERATE VERTICAL WIND SHEAR (10-15 KNOTS) AND VERY WARM SEA
SURFACE TEMPERATURES (30-31 CELSIUS). GLOBAL MODELS ARE NOT
INDICATING DEVELOPMENT AS ENHANCED SOUTHWESTERLY FLOW INTO NEARBY
TS 25W WILL PREVENT THE SURFACE CIRCULATION FROM PERSISTING AS IT
MOVES SLOWLY EASTWARD TOWARDS THE PHILIPPINES. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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 LOW.

(2) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED
NEAR 12N 118.3E, IS NOW LOCATED NEAR 9.2N 115.3E, APPROXIMATELY 443
NM SOUTHWEST OF MANILA PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC)
WITH BROAD CONVECTION WRAPPING IN FROM THE SOUTH WESTERN PERIPHERY.
A 180141Z 89GHZ AMSU IMAGE SHOWS AN ELONGATED AND DISORGANIZED
CIRCULATION CENTER WITH SCATTERED CONVECTION THROUGHOUT THE SOUTH
WESTERN PORTION OF THE DISTURBANCE. THE UPPER LEVEL ANALYSIS SHOWS
THAT THE DISTURBANCE IS CURRENTLY LOCATED IN AN AREA OF GOOD UPPER
LEVEL DIVERGENCE, BUT IS CURRENTLY BORDERING AN AREA OF MARGINAL
VERTICAL WIND SHEAR (15-20 KNOTS), WITH WARM SEA SURFACE
TEMPERATURES (30-31 CELSIUS). GLOBAL MODELS ARE INDICATING THE
POSSIBILITY OF DEVELOPMENT IN THE NEXT 24 TO 48 HOURS AS ENHANCED
SOUTHWESTERLY FLOW FEDS INTO THE CIRCULATION. HOWEVER, THE SYSTEM
SHOULD BE FAIRLY WEAK AND SHORT-LIVED AS IT TRACKS EASTWARD AND
GETS ABSORBED INTO NEARBY TY 25W. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF
A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED
TO HIGH. SEE REF B (WTPN PGTW 180830) FOR FURTHER DETAILS.
