(2) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR
11.8N 143.7E, APPROXIMATELY 128 NM WEST OF ANDERSEN AFB, GUAM.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A RAGGED AND
ELONGATED LOW- LEVEL CIRCULATION CENTER (LLCC) EMBEDDED IN FLARING,
SHALLOW, AND DISORGANIZED CONVECTION. A 072050Z SSMIS 91GHZ
MICROWAVE IMAGE DEPICTS FRAGMENTED BANDING WRAPPING INTO A BROAD AND
ILL-DEFINED CENTER. THE SYSTEM IS LOCATED IN A MARGINAL ENVIRONMENT
WITH LIGHT TO MODERATE (10-15 KNOT) VERTICAL WIND SHEAR.
FURTHERMORE, A TUTT CELL TO THE NORTHWEST IS CAUSING SUBSIDENCE.
HOWEVER, EQUATORWARD OUTFLOW IS PROVIDING SOME VENTILATION TO THE
ASSOCIATED CONVECTION. DYNAMIC MODEL GUIDANCE INDICATES NO
SIGNIFICANT DEVELOPMENT AS THE DISTURBANCE TRACKS POLEWARD OVER THE
NEXT DAY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 12 TO 18
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 LOW
