1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 19OCT20 1800Z, TROPICAL DEPRESSION 19W (NINETEEN) WAS 
LOCATED NEAR 15.0N 126.1E, APPROXIMATELY 297 NM EAST OF MANILA, 
PHILIPPINES, AND HAD TRACKED WEST-NORTHWESTWARD AT 11 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 
KNOTS GUSTING TO 40 KNOTS. SEE REF A (WTPN31 PGTW 192100) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED 
NEAR 22.6N 139.4E IS NOW LOCATED NEAR 24.1N 138.8E, APPROXIMATELY 
140 NM WEST-SOUTHWEST OF IWO TO. ANIMATED INFRARED SATELLITE IMAGERY 
AND A 191930Z SSMIS 91GHZ IMAGE DEPICTS A REGION OF CONVECTIVE 
BANDING AROUND A SMALL, DEFINED LOW LEVEL CIRCULATION OBSCURED BY 
DEEP CONVECTION OVER THE CENTER. INVEST 97W IS IN A MARGINALLY 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH GOOD EQUATORWARD OUTFLOW 
ALOFT, WARM (28-29C) SEA SURFACE TEMPERATURES, ONLY OFFSET BY 
MODERATE-HIGH (20-30 KNOTS) VERTICAL WIND SHEAR. GLOBAL MODELS 
INDICATE INVEST 97W WILL TRACK NORTH-NORTHWESTWARD WITH SLIGHT 
INTENSIFICATION OVER THE NEXT 24 HOURS AS 19W MOVES WEST. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR 
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS IS UPGRADED TO MEDIUM.
      (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: UPGRADED AREA IN PARA 1.B.(1) TO MED.//
