RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED 
NEAR 4.0N 137.7E, IS NOW LOCATED NEAR 4.8N 133.9E, APPROXIMATELY 160 
NM SOUTH-SOUTHWEST OF PALAU. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY DEPICTS A BROAD AREA OF TROUGHING WITH LIMITED, 
DISORGANIZED, AND FRAGMENTED CONVECTION. A 170017Z AMSU-B 89GHZ 
MICROWAVE IMAGE DEPICTS A LARGE AREA WITH MOSTLY SHALLOW CONVECTION 
AROUND THE PERIPHERY OF A WEAK LLCC. THE DISTURBANCE IS CURRENTLY 
LOCATED IN A MARGINAL ENVIRONMENT WITH GOOD DIVERGENCE ALOFT AND 
WARM SEA SURFACE TEMPERATURES (28-30 CELSIUS), BUT HAS MOVED INTO AN 
AREA OF MODERATE TO HIGH VERTICAL WIND SHEAR (20-25 KNOTS). GLOBAL 
MODELS ARE IN AGREEMENT THAT THE DISTURBANCE WILL MOVE TO THE WEST-
NORTHWEST OVER THE NEXT SEVERAL DAYS, HOWEVER, THEY ARE DIVIDED ON 
THE TIMING AND DEGREE OF INTENSIFICATION. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):

Issued at 2:00 pm WST on Wednesday 17 January 2018for the period until midnight WST Saturday 20 January 2018.

Nil.
Potential Cyclones:

A monsoon trough extends across the central tropical Indian Ocean to a weak tropical low which was near 15.4S 105.6E at 1pm WST Wednesday, which is about 550km south of Christmas Island. The system is expected to continue moving west over the next few days and is unlikely to develop into a tropical cyclone.

The monsoon trough is expected to become more active north of WA over the weekend. A significant tropical low is unlikely to develop in the trough over the next three days, but the risk of a system developing increases next week.

Likelihood of a tropical cyclone in the Western Region on:

Thursday:Very Low

Friday:Very Low

Saturday:Very 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%
