RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 91W) HAS PERSISTED NEAR 6.0N 
168.0E, APPROXIMATELY 130 NM SOUTH-SOUTHWEST OF KWAJALEIN ISLAND. 
ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS A CONSOLIDATING 
AREA OF CONVECTION WITH FEEDER BANDS TO THE NORTH AND FLARING 
CONVECTION WITH OVERSHOOTING TOPS JUST SOUTH OF A LOW LEVEL 
CIRCULATION (LLC). A 071913Z SSMIS 91GHZ MICROWAVE PASS DEPICTS 
FRAGMENTED BANDING WRAPPING INTO THE LLC WITH THE AFOREMENTIONED 
CONVECTION TO THE SOUTH. INVEST 91W IS IN AN ENVIRONMENT FAVORABLE 
FOR TROPICAL DEVELOPMENT WITH GOOD EQUATORWARD OUTFLOW ALOFT, LOW (5-
10KTS) VERTICAL WIND SHEAR (VWS) AND WARM (30-31C) SEA SURFACE 
TEMPERATURES (SST). GLOBAL MODELS ARE NOT IN AGREEMENT WITH A 
TROPICAL CYCLONE DEVELOPING FROM INVEST 91W, HOWEVER, JTWC WILL 
CLOSELY MONITOR FOR POTENTIAL DEVELOPMENT DUE TO A FAVORABLE 
APPEARANCE IN SATELLITE ANALYSIS. MAXIMUM SUSTAINED SURFACE WINDS 
ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED AREA IN PARA. 1.B.(1) AS LOW.//
