1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 07NOV20 1200Z, TROPICAL DEPRESSION 23W (ATSANI) WAS 
LOCATED NEAR 22.6N 118.6E, APPROXIMATELY 219 NM SOUTHWEST OF TAIPEI, 
TAIWAN, AND HAD TRACKED WESTWARD AT 06 KNOTS (KTS) OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS 
GUSTING TO 35 KNOTS. SEE REF A (WTPN32 PGTW 071500) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED 
NEAR 11.2N 127.4E IS NOW LOCATED NEAR 13.0N 120.8E, APPROXIMATELY 96 
NM SOUTH OF MANILA, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY DEPICTS PERSISTENT DEEP CONVECTION SLIGHTLY SHEARED TO THE 
WEST OF THE LOW LEVEL CIRCULATION (LLC) STRUGGLING AGAINST THE 
FRICTION EFFECTS FROM THE PHILIPPINE ISLANDS. A 072243Z SSMIS 91GHZ 
MICROWAVE IMAGE REVEALS DEEP CONVECTION ALONG WITH SHALLOWER 
CONVECTIVE BANDING FORMING TO THE EAST. 92W IS CURRENTLY IN AN 
UNFAVORABLE ENVIRONMENT WITH MODERATE UPPER LEVEL OUTFLOW AND WARM 
(29-30C) SEA SURFACE TEMPERATURES BEING HEAVILY OFFSET BY MODERATE 
TO UNFAVORABLE (20-25KTS) VERTICAL WIND SHEAR AND LAND INTERACTION 
AS 92W TRANSITS THE PHILIPPINE ISLANDS. GLOBAL MODELS ARE IN GOOD 
AGREEMENT THAT 92W WILL TRACK WESTWARD WITH LITTLE INTENSIFICATION 
WHILE OVER THE PHILIPPINES. AFTER 92W ENTERS THE SOUTH CHINA SEA IN 
THE NEXT 24 HOURS HOWEVER, MODELS EXPECT IT TO SLIGHTLY INTENSIFY TO 
WARNING THRESHOLD WITH MINIMAL FURTHER INTENSIFICATION AS IT CROSSES 
THE SOUTH CHINA SEA. 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 REMAINS HIGH. SEE REF B 
(WTPN21 PGTW 071500) FOR FURTHER DETAILS.
      (2) AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR 8.4N 
134.3E, APPROXIMATELY 69 NM NORTH OF PALAU. ANIMATED MULTISPECTRAL 
SATELLITE IMAGERY AND A 080045Z METOP-B 89GHZ MICROWAVE IMAGE REVEAL 
A DISORGANIZED LOW LEVEL CIRCULATION WITH SOME FORMATIVE BANDING IN 
THE NORTHERN SEMICIRCLE. INVEST 93W IS IN A FAVORABLE ENVIRONMENT 
FOR DEVELOPMENT WITH MODERATE UPPER LEVEL OUTFLOW, LOW (<15KTS) 
VERTICAL WIND SHEAR, AND WARM (29-30C) SEA SURFACE TEMPERATURES. 
GLOBAL MODELS ARE IN GENERAL AGREEMENT THAT INVEST 93W WILL QUICKLY 
INTENSIFY AS IT TRACKS NORTH-NORTHWESTWARD OVER THE NEXT 24-36 
HOURS. 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 LOW.
      (3) 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.(2) AS LOW.//
