2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.3N
131.3E, IS NOW LOCATED NEAR 9.4N 129.0E, APPROXIMATELY 180 NM EAST
OF MINDANAO, PHILIPPINES. ANIMATED INFRARED SATELLITE IMAGERY SHOWS
AN IMPROVED LOW LEVEL CIRCULATION CENTER (LLCC) ASSOCIATED WITH
INCREASED DEEP CONVECTION ALTHOUGH STILL UNORGANIZED. A 041116Z
SSMIS MICROWAVE IMAGE DEPICTS IMPROVED LOW LEVEL INFLOW AND A
040922Z WINDSAT PASS DEPICTS A WELL-DEFINED LLCC WITH 15 TO 20 KNOT
CENTRAL WINDS. ADDITIONALLY, A BUOY APPROXIMATELY 100 NM AWAY IS
REPORTING A 1005 MB SEA LEVEL PRESSURE AND FAVORABLE SEA SURFACE
TEMPERATURES OF 29 DEGREES CELSIUS. UPPER LEVEL ANALYSIS INDICATES
THE LLCC IS LOCATED BENEATH THE RIDGE AXIS IN AN AREA OF LOW
VERTICAL WIND SHEAR AND EXCELLENT UPPER LEVEL DIVERGENCE. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO GOOD. |
