/REISSUED/212200Z-221800ZJAN2018//
RMKS/
1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE 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 99S) HAS PERSISTED NEAR 
19.6S 47.6E, APPROXIMATELY 50 NM SOUTHEAST OF ANTANANARIVO, 
MADAGASCAR. ANIMATED ENHANCED INFRARED IMAGERY SHOWS IMPROVED 
FLARING CONVECTION DIRECTLY ABOVE A LOW LEVEL CIRCULATION CENTER AS 
99S MOVES OUT OVER OPEN WATER. SEA SURFACE TEMPERATURES IMMEDIATELY 
OFF THE COAST OF MADAGASCAR ARE MARGINAL (26-27 CELSIUS) AND 
DECREASE TO THE SOUTHEAST. HOWEVER THIS IS OFFSET BY DUAL CHANNEL 
OUTFLOW AND THAT 99S IS MOVING INTO A REGION OF LOW (10-15 KNOT) 
VERTICAL WIND SHEAR. GLOBAL DYNAMIC MODELS GENERALLY FAVOR LIGHT 
DEVELOPMENT IN THE NEAR TERM AS 99S MOVES EASTWARD. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR 
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.

IDW10800
Australian Government Bureau of MeteorologyWestern Australia
Tropical Cyclone Outlook for the Western Region
Issued at 2:00 pm WST on Sunday 21 January 2018for the period until midnight WST Wednesday 24 January 2018.
Existing Cyclones in the Western Region:
Nil.
Potential Cyclones:

The monsoon trough lies just south of Indonesia and extends through the Timor Sea and over the Top End of the Northern Territory. A tropical low may develop over the Top End on Monday, but it is unlikely to enter the Western Region before Wednesday. With the monsoon trough well established, there is the chance of another tropical low developing along the trough on Tuesday or Wednesday, anywhere between 95E and 115E. As a result, the risk of a tropical cyclone occurring in the Western Region gradually increases during the week.

Likelihood of a tropical cyclone in the Western Region on:

Monday:Very Low

Tuesday:Low

Wednesday:Low

NOTES: The likelihood is an estimate of the chance of each system being a tropical cyclone in the Region for each day.

Very Low:
less than 5%
Low:
5% to 20%

Moderate:
20 to 50%
High:
Over 50%

The Western Region refers to the Indian Ocean between Longitudes 90-125E and south of 10S.

Tropical Cyclone Outlook for the Northern Region, including the Gulf of Carpentaria
Issued at 2:15 pm CST on Sunday 21 January 2018for the period until midnight CST Wednesday 24 January 2018.
Existing Cyclones in the Northern Region:
Nil.
Potential Cyclones:

The monsoon trough extends northwest to southeast across the Top End. A weak Tropical Low, 1000 hPa, is located over land in the monsoon trough to the west of Borroloola. The Low is expected to remain slow moving tonight and on Monday, before moving to the west. Although it is most likely that the Low will remain over land for the next few days, if it does move over water there is a low chance of it intensifying over the southern Gulf of Carpentaria on Monday or Tuesday.
Although the movement of the Low is uncertain in the longer term, the risk of a Tropical Cyclone developing remains low on Wednesday.

Likelihood of a tropical cyclone in the Northern Region on:

Monday:Low.

Tuesday:Low.

Wednesday:Low.

NOTES: The likelihood is an estimate of the chance of each system being a tropical cyclone in the Region for each day.

Very Low:
less than 5%
Low:
5% to 20%

Moderate:
20 to 50%
High:
Over 50%

The area of coverage for this outlook is the Ocean area south of 9S, between 125E and 142E, including the Gulf of Carpentaria, but excluding the area around Timor (northwest of 11S 125E, 11S 128E, 9S 128E).
