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:
      (1) AT 29JAN23 0000Z, TROPICAL CYCLONE 08S (CHENESO) WAS LOCATED 
NEAR 27.7S 43.9E, APPROXIMATELY 386 NM SOUTH-SOUTHEAST OF EUROPA 
ISLAND, AND HAD TRACKED SOUTHEASTWARD AT 17 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 60 KNOTS 
GUSTING TO 75 KNOTS. SEE REF A (WTXS31 PGTW 290300) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 94S) HAS PERSISTED NEAR 10.2S 
95.4E, APPROXIMATELY 146 NM NORTHWEST OF THE COCOS ISLANDS. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY DEPICTS FLARING DEEP CONVECTION OVER A 
BROAD LOW-LEVEL CIRCULATION (LLC). A 290949Z SSMIS 91GHZ MICROWAVE 
IMAGE INDICATES SHALLOW BANDING WRAPPING INTO A BROAD LLC WITH LIMITED 
DEEP CONVECTIVE BANDING OVER THE EASTERN QUADRANT. SURFACE OBSERVATIONS 
FROM THE COCOS ISLANDS INDICATE SOUTHEASTERLY WINDS AT 10-15 KNOTS WITH 
SLP NEAR 1004MB. ENVIRONMENTAL CONDITIONS ARE MARGINAL WITH MODERATE TO 
HIGH VERTICAL WIND SHEAR OFFSET BY BROAD DIFFLUENT FLOW ALOFT. GLOBAL 
MODELS INDICATE A WEST-SOUTHWESTWARD TRACK OVER THE NEXT TWO DAYS WITH 
SLOW DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 
TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 
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.
3. JUSTIFICATION FOR REISSUE: ADDED LOW AREA IN PARAGRAPH 2.B.(1).//
