Indian Ocean Tropical Storm Risk

Indian Ocean Tropical Weather Outlook from the JTWC

North Indian Ocean

1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR 14.7N 
98.6E, APPROXIMATELY 181 NM SOUTHEAST OF YANGON. ANIMATED ENHANCED 
INFRARED (EIR) SATELLITE IMAGERY DEPICTS A BROAD LOW LEVEL CIRCULATION 
CENTER (LLCC) WITH DEEP CONVECTION PERSISTING OVER THE SOUTHERN SEMI-
CIRCLE. A 262219Z SSMIS 91GHZ MICROWAVE IMAGE REVEALS FORMATIVE CURVED 
BANDING OVER WATER WRAPPING INTO THE SOUTHEAST QUADRANT. ENVIRONMENTAL 
ANALYSIS INDICATES A MARGINAL ENVIRONMENT WITH LOW TO MODERATE VERTICAL 
WIND SHEAR (15-20KTS), GOOD EQUATORWARD OUTFLOW AND WARM SEA SURFACE 
TEMPERATURES (28-29C). GLOBAL DETERMINISTIC AND ENSEMBLE MODELS INDICATE 
A VERY SLOW DEVELOPMENT WITHIN 48 HOURS AS THE SYSTEM FOLLOWS THE COAST 
OF MYANMAR MOVING NORTH-NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS 
ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1004 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.

South Indian Ocean

2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane 
Polo, located southwest of Cabo San Lucas, Mexico, on Hurricane 
Odalys, located well west of the southern tip of Baja California, 
and on Hurricane Nolo, located south-southwest of the Big Island of 
Hawaii, and newly formed Tropical Depression Eighteen-E, located 
several hundred miles southwest of the Acapulco, Mexico.

Well East-Southeast of the Hawaiian Islands:
Showers and thunderstorms continue to develop around a broad area of 
low pressure, currently located well east-southeast of the Hawaiian 
Islands. Environmental conditions are expected to be conducive for 
further development, and a tropical depression is likely to form in 
the next several days. The system is expected to move generally 
northeastward, and remain well east-southeast of the Hawaiian 
Islands.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...high...80 percent.

For the North Atlantic...Caribbean Sea and the Gulf of America:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Depression Fay, located well to the west-southwest of the Azores.

Central Subtropical Atlantic:
A surface trough of low pressure located several hundred miles east 
of Bermuda continues to produce an area of disorganized showers and

for gradual development of this system, and a tropical depression 
could form by the early to mid portion of this week as it initially 
moves northward before turning eastward early this week over the 
central Subtropical Atlantic. 
* Formation chance through 48 hours...low...30 percent.
