B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION (INVEST 95W) HAS PERSISTED NEAR
27.4N 161.8E, APPROXIMATELY 550 NM NORTH-NORTHWEST OF WAKE ISLAND.
MULTISPECTRAL SATELLITE IMAGERY SHOWS PARTIALLY ORGANIZED DEEP
CONVECTION WITH LOW LEVEL CLOUDS BEGINNING TO WRAP INTO A
DEVELOPING LLCC. WEAK OUTFLOW IS OFFSET BY LOW (5-10KT) VERTICAL
WIND SHEAR. THERE IS SLIGHT IMPROVEMENT IN THE SYMMETRY AND
STRENGTH OF THE 850MB VORTICITY SIGNATURE. SST IS FAVORABLE AT 29C
AND THE SYSTEM IS STILL BEING ASSESSED AS TROPICAL. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1013 MB. THE POTENTIAL
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE
NEXT 24 HOURS IS UPGRADED TO LOW.
