REISSUED/212000Z-221800ZJAN2023//
RMKS/
1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 08S) HAS PERSISTED NEAR 19.0S 
45.1E, APPROXIMATELY 136 NM EAST OF ANTANANARIVO, MADAGASCAR. ANIMATED 
ENHANCED INFRARED IMAGERY AND A 211830Z MSG-4 IR IMAGE DEPICTS A FULLY 
OBSCURED BROAD BUILDING CIRCULATION, WITH ITS CENTER OF CONVECTION OFFSET 
TO THE WEST. ENVIRONMENTAL ANALYSIS INDICATES 08S WILL REDEVELOP AFTER IT 
ENTERS THE MOZAMBIQUE CHANNEL DUE TO LOW (5-10 KNOTS) VERTICAL WIND 
SHEAR, GOOD POLEWARD UPPER LEVEL OUTFLOW AND VERY WARM (29-30C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 08S WILL 
TRACK SOUTHWESTWARD AND REDEVELOP AFTER REENTERING OPEN WATER ON OR 
AROUND 24 JAN AT 00Z. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 
TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. 
THE POTENTIAL FOR THE REDEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED THE REMNANTS OF 08S AS A LOW IN PARA 
2.B(1).//
