(1) AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR
19.7N 133.5E, APPROXIMATELY 530 NM SOUTHWEST OF IWO TO, JAPAN.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD, ELONGATED
LOW LEVEL CIRCULATION CENTER (LLCC) WITH DISORGANIZED FLARING
CONVECTION. AN 182226Z GMI 89 GHZ MICROWAVE IMAGE SHOWS LOW LEVEL
BANDING WRAPPING INTO A BROAD LLCC. UPPER LEVEL ANALYSIS REVEALS A
MODERATELY FAVORABLE ENVIRONMENT WITH WEAK OUTFLOW AND MODERATE (15-
20 KTS) VERTICAL WIND SHEAR. THE SYSTEM IS CURRENTLY TRACKING
THROUGH AN AREA OF WARM (29 CELSIUS) SEA SURFACE TEMPERATURES.
GLOBAL MODELS ARE IN AGREEMENT THAT THE DISTURBANCE WILL TRACK TO
THE NORTHWEST WITH DEVELOPMENT LIKELY AFTER TAU 36. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15-20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
