1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 15DEC22 0000Z, TROPICAL CYCLONE 07A (SEVEN) WAS LOCATED 
NEAR 13.5N 67.8E, APPROXIMATELY 662 NM SOUTHEAST OF MASIRAH ISLAND, AND 
HAD TRACKED WESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 KNOTS. 
SEE REF A (WTIO31 PGTW 150300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   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) THE AREA OF CONVECTION (INVEST 98S) PREVIOUSLY LOCATED NEAR 
9.6S 91.3E IS NOW LOCATED NEAR 9.6S 95.5E, APPROXIMATELY 168 NM NORTH-
NORTHWEST OF COCOS ISLANDS, AUSTRALIA. MULTISPECTRAL SATELLITE IMAGERY 
(MSI) DEPICTS A PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) 
WITH STRONGER WINDS NOW WRAPPING AROUND THE CIRCULATION THE SOUTHERN AND 
WESTERN SIDES OF THE CIRCULATION, AS SEEN IN A 150305Z ASCAT METOP-B 
PASS. ENVIRONMENTAL ANALYSIS INDICATES LOW VERTICAL WIND SHEAR (VWS) 
OFFSET BY GOOD DIVERGENCE ALOFT AND WARM (28-29C) SEA SURFACE 
TEMPERATURES (SST). GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 98S 
WILL CONTINUE TO TRACK SLOWLY TO THE WEST AND GRADUALLY CONSOLIDATE AND 
INTENSIFY OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 27 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO 
BE NEAR 1008 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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO MEDIUM//
