RMKS/
1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO
COAST OF AFRICA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 071800Z0, TROPICAL STORM LINDA (30W) WAS
LOCATED AT 14.9N4 90.6E5, AND WAS QUASI-STATIONARY.
MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 50 KNOTS
WITH GUSTS TO 65 KNOTS.  SEE REF A (TROPICAL STORM LINDA
(30W) WARNING NR 29 (WTIO32 PGTW 072100)) AND SIX-HOURLY
UPDATES FOR FURTHER DETAILS.
(2) NO OTHER SIGNIFICANT TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR
9N9 54E9 HAS NOT MOVED OVER THE PAST THREE HOURS.
ANIMATED INFRARED SATELLITE IMAGERY, 071200Z0 AND
071800Z6 SHIP DATA INDICATE A WELL-DEFINED LOW-LEVEL
CYCLONIC CIRCULATION BENEATH UPPER-LEVEL ANTICYCLONIC
FLOW.  IN ADDITION, CONVECTION CONTINUES TO DEVELOP NEAR
THE LOW LEVEL CIRCULATION CENTER.  TWO SHIP REPORTS OF 20
KNOTS HAVE BEEN RECEIVED WITHIN 5 DEGREES OF THE
CIRCULATION CENTER DURING THE PAST 6 HOURS.  MAXIMUM
SUSTAINED WINDS ARE ESTIMATED AT 15 TO 25 KNOTS.  MINIMUM
SEA LEVEL PRESSURE IS ESTIMATED TO BE 1010 MB.  THE
POTENTIAL FOR SIGNIFICANT TROPICAL CYCLONE DEVELOPMENT
WITHIN THE NEXT 24 HOURS IS FAIR.
(2) THE AREA OF CONVECTION MENTIONED PREVIOUSLY NEAR
8N8 82E0 IS NOW LOCATED NEAR 10N1 79E6.  A WEAK LOW-LEVEL
CYCLONIC CIRCULATION EXISTS BENEATH A SMALL UPPER-LEVEL
ANTICYCLONE.  SATELLITE IMAGERY CONTINUES TO SHOW GOOD
CYCLONIC TURNING OF THE DEEP CONVECTION.  HOWEVER, THE
SURFACE CIRCULATION HAS MOVED ONSHORE OVER THE EXTREME
SOUTHEAST TIP OF INDIA AND LAND INTERACTION WILL INHIBIT
ANY FURTHER DEVELOPMENT.  SURFACE PRESSURES ALSO REMAIN
HIGH IN THIS AREA.  MAXIMUM SUSTAINED WINDS ARE ESTIMATED
AT 10 TO 15 KNOTS.  MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE 1010 MB.  THE POTENTIAL FOR SIGNIFICANT
TROPICAL CYCLONE DEVELOPMENT WITHIN THE NEXT 24 HOURS IS
POOR.
(3) NO OTHER SUSPECT AREAS.
2. SOUTH INDIAN OCEAN AREA (135E9 WEST TO COAST OF
AFRICA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
3. JUSTIFICATION: TO UPGRADE SUSPECT AREA IN PARAGRAPH
1.B(1).
