JTWC：DOWNGRADED TO LOW
                                        THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 18.2S
39.1E, IS NOW LOCATED NEAR 21.0S 36.6E, APPROXIMATELY 370 NM
NORTHEAST OF MAPUTO, MOZAMBIQUE. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS AN ELONGATING, FULLY-EXPOSED LOW-LEVEL CIRCULATION
CENTER (LLCC) WITH ISOLATED DEEP CONVECTION FLARING OVER THE
NORTHWEST QUADRANT OF THE LLCC. A 300633Z ASCAT PASS INDICATED WINDS
NEAR THE CENTER HAVE WEAKENED OVER THE PAST 24 HOURS, WITH A MAXIMUM
BETWEEN 20 TO 25 KNOTS. UPPER LEVEL ANALYSIS INDICATES THE
ENVIRONMENT IS MARGINAL WITH A RIDGE TO THE SOUTHWEST CREATING
MODERATE LEVELS (20 TO 25 KNOTS) OF VERTICAL WIND SHEAR OVER THE
LLCC. DYNAMIC MODEL GUIDANCE INDICATES THAT THE SYSTEM WILL CONTINUE
TO WEAKEN AS IT TRACKS SOUTHWESTWARD. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 20 TO 25 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 DOWNGRADED
TO LOW.
