1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 220600Z, TROPICAL DEPRESSION 26W (TWENTYSIX) WAS
LOCATED NEAR 7.5N 148.5E, APPROXIMATELY 410 NM SOUTHEAST OF GUAM,
AND HAD TRACKED NORTH-NORTHWESTWARD AT 09 KNOTS OVER THE PAST SIX
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS
GUSTING TO 40 KNOTS. SEE REF A (WTPN31 PGTW 220900) FOR FURTHER
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 7.8N
128.9E, IS NOW LOCATED NEAR 8.2N 128.2E, APPROXIMATELY 390 NM WEST
OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS CONTINUED
CONSOLIDATION OF DEEP CONVECTION NEAR A WELL-DEFINED LOW LEVEL
CIRCULATION CENTER (LLCC) AND A 220500Z AMSRE AQUA MICROWAVE IMAGE
SHOWS MULTIPLE CONVECTIVE BANDS CONVERGING INTO THE SYSTEM CENTER.
THE 220035Z ASCAT PASS ALSO REVEALS A SYMMETRIC LLCC WITH 20-KNOT
WINDS. ENVIRONMENTAL ANALYSIS INDICATES THE SYSTEM IS IN AN AREA OF
MINIMAL VERTICAL WIND SHEAR AND HAS DIVERGENT FLOW ALOFT. AN
UPSTREAM MID-LATITUDE TROUGH IS ALSO STARTING TO PROVIDE INCREASED
POLEWARD OUTFLOW. A CIRCLE WAS USED FOR THE TROPICAL CYCLONE
FORMATION ALERT AREA TO CONVEY NEAR-TERM TRACK UNCERTAINTY DUE TO
THE SYSTEM BEING IN A DUAL STEERING ENVIRONMENT. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 17 TO 22 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. GIVEN AN INCREASE IN
CONVECTIVE CONSOLIDATION AND IMPROVING POLEWARD OUTFLOW, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD. SEE REF B (WTPN21 PGTW
221000) FOR FURTHER DETAILS.
      (2) AN AREA OF CONVECTION HAS PERSISTED NEAR 3.7N 107.8E,
APPROXIMATELY 285 NM EAST-NORTHEAST OF SINGAPORE. ANIMATED INFRARED
IMAGERY SHOWS CYCLONIC TURNING OF DEEP CONVECTION OVER A LOOSELY-
DEFINED LOW LEVEL CIRCULATION CENTER (LLCC). IN ADDITION,
NORTHEASTERLY LOW-LEVEL WINDS CAUSED BY A COLD SURGE THROUGH THE
SOUTH CHINA SEA ARE ENHANCING THE LOW-LEVEL VORTICITY IN THE AREA.
HOWEVER, EASTERLY VERTICAL WIND SHEAR IS CURRENTLY UNFAVORABLE FOR
DEVELOPMENT. NEVERTHELESS, AS THE WIND SHEAR RELAXES, THERE IS
EVENTUAL DEVELOPMENT OF A DEPRESSION-STRENGTH CYCLONE BY THREE OF
THE GLOBAL MODELS. MAXIMUM SUSTAINED SURFACE WINDS (NOT ASSOCIATED
WITH THE STRONGER GRADIENT WINDS TO THE NORTH) ARE ESTIMATED AT 12
TO 17 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 POOR.
      (3) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO GOOD
AND ADDED AREA IN PARA 1.B.(2) AS POOR.//
