B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED
NEAR 6.3N 148.7E IS NOW LOCATED NEAR 6.1N 147.6E, APPROXIMATELY 596
NM EAST-SOUTHEAST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
AND A 030000Z 89GHZ METOP-B IMAGE REVEAL AN AREA OF CONVECTION
WITHOUT A CLEAR LOW LEVEL CIRCULATION. THE UPPER LEVEL ENVIRONMENT
IS UNFAVORABLE FOR DEVELOPMENT WITH WESTWARD FLOW ALOFT OFFSET BY
HIGH (25-35 KTS) VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES
REMAIN FAVORABLE FOR DEVELOPMENT AT 29-30C. GLOBAL MODELS ARE IN
GOOD AGREEMENT THAT 95W WILL CONTINUE TO TRACK WESTWARD AS AN
ELONGATED CIRCULATION WITH MARGINAL TO NO DEVELOPMENT.  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 DOWNGRADED TO LOW.

1. REMARKS: THIS CANCELS REF A (WTPN21 PGTW 010300). THE AREA OF
CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR 7.2N 154.0E IS NOW
LOCATED NEAR 6.2N 149.3E, APPROXIMATELY 125 NM EAST OF CHUUK.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 012306Z 89GHZ MHS
IMAGE REVEAL AN AREA OF SHEARED CONVECTION OVER A BROAD LOW LEVEL
CIRCULATION CENTER (LLCC). THE UPPER LEVEL ENVIRONMENT IS MODERATELY
FAVORABLE WITH GOOD EQUATORWARD OUTFLOW AND MODERATE (15-25 KTS)
VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES REMAIN FAVORABLE FOR
DEVELOPMENT AT 29-30C. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 95W
WILL CONTINUE TO TRACK WESTWARD WITH MINIMAL DEVELOPMENT. 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

(1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED
NEAR 6.7N 158.7E IS NOW LOCATED NEAR 7.2N 155.8E, APPROXIMATELY 233
NM EAST OF CHUUK. ANIMATED MULTISPECTRAL SATELLITE IMAGERY REVEALS
AN EXPOSED, CONSOLIDATING LOW LEVEL CIRCULATION (LLC) WITH POCKETS
OF FLARING CONVECTION DISPLACED TO THE NORTH. A 300421Z GMI 89GHZ
MICROWAVE IMAGE FURTHER DEPICTS A DEFINED LLC AND ADDITIONAL
CONVECTION OFFSET TO THE NORTHWEST. A 292207Z ASCAT-A PASS REVEALS
15-20 KNOT WINDS WRAPPING AROUND THE LLC WITH HIGHER 30-35 KNOT
WINDS DISPLACED TO THE SOUTHWEST. 95W IS CURRENTLY IN A MARGINAL
ENVIRONMENT FOR DEVELOPMENT WITH HIGH (30-40 KTS) VERTICAL WIND
SHEAR OFFSET BY WARM (29-30C) SEA SURFACE TEMPERATURES AND
DIVERGENCE ALOFT. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 95W WILL
TRACK GENERALLY WESTWARD AND CONTINUE TO CONSOLIDATE OVER THE NEXT
24 HOURS.  MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB.

(2) AN AREA OF CONVECTION (INVEST 95W) HAS PERSISTED NEAR 6.7N
158.7E, APPROXIMATELY 30 NM EAST-SOUTHEAST OF POHNPEI. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY REVEALS A BROAD, WEAK LOW LEVEL
CIRCULATION (LLC) WITH DEEP CONVECTION SURROUNDING THE LLC, BUT NOT
OVERHEAD. A 290429Z SSMI F-15 85GHZ MICROWAVE IMAGE SHOWS A COMPLETE
LACK OF CONVECTIVE STRUCTURE. 95W IS CURRENTLY IN A FAVORABLE
ENVIRONMENT WITH GOOD EQUATORWARD OUTFLOW, WARM (28 TO 29 CELSIUS)
SEA SURFACE TEMPERATURES, AND LOW (5 TO 10 KNOT) VERTICAL WIND
SHEAR. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 95W WILL TRACK
GENERALLY WESTWARD AND CONSOLIDATE TO WARNING STATUS IN THE NEXT
SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO
15 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.
