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) THE AREA OF CONVECTION 
(INVEST 94S) PREVIOUSLY LOCATED NEAR 18.8S 34.6E, IS NOW LOCATED 
NEAR 23.8S 39.1E, APPROXIMATELY 215 NM SOUTH-SOUTHWEST OF EUROPA 
ISLAND. ANIMATED ENHANCED INFRARED IMAGERY DEPICTS AN AREA OF VERY 
BROAD, ELONGATED TURNING EMBEDDED WITH SEVERAL SMALL VORTICES. A 
181455Z SSMIS 91GHZ IMAGE INDICATES THERE IS WEAK, SCATTERED 
CONVECTION LINEARLY ORIENTED IN THE AREA. 94S IS LOCATED ON THE CUSP 
OF HIGH VERTICAL WIND SHEAR (25-30 KTS), GOOD POLEWARD OUTFLOW, AND 
WARM SEA SURFACE TEMPERATURES (28-29C). GLOBAL MODELS HAVE EASED OFF 
ON SIGNIFICANT DEVELOPMENT OF THE SYSTEM AS INTERACTION WITH 
MADAGASCAR WILL INHIBIT INTENSIFICATION.  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 REMAINS LOW.

Australian Government Bureau of MeteorologyQueensland
Updated Tropical Cyclone Outlook for Coral Sea
Issued at 3:36 pm EST on Tuesday 19 February 2019for the period until midnight EST Friday 22 February 2019.
Existing Cyclones in the Eastern Region:
Nil.
Potential Cyclones:

At 2pm AEST Tuesday, tropical cyclone Oma was located off the northwest tip of New Caledonia [about 1,400 kilometres east of Mackay] and moving in a southwesterly direction. Refer to the Fiji Meteorological Service web site for the latest Forecast Track Map [http://www.met.gov.fj].

Tropical cyclone Oma is expected to move west of longitude 160E and enter the Eastern Region early Thursday morning, although it may be as early as Wednesday evening. It is likely to continue tracking slowly in a southwesterly direction towards the east coast of Queensland late this week and over the weekend, resulting in hazardous surf conditions and abnormally high tides developing about the southern Queensland and far northern New South Wales coasts from Wednesday.

While some models have the tropical cyclone remaining offshore of southern Queensland, there is a possibility that the tropical cyclone may near or even cross the east coast late in the weekend. The position of the tropical cyclone will depend on the movement and development of an upper level trough during the coming days.

There are no other significant tropical lows in the region, and none are expected to develop during the next three days.

Likelihood of a tropical cyclone in the Eastern Region on:

Wednesday:Moderate

Thursday:High

Friday:High

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 Coral Sea and northern Tasman Sea west of 160E.
