(1) AN AREA OF CONVECTION (INVEST 92P) HAS PERSISTED NEAR 15.8S
147.9E, APPROXIMATELY 123 NM WEST-NORTHWEST OF WILLIS ISLAND,
AUSTRALIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) REVEALS A
FULLY EXPOSED AND ELONGATED LOW-LEVEL CIRCULATION CENTER (LLCC),
CHARACTERIZED BY MULTIPLE FLARING VERTICAL HOT TOWERS IN THE IMMEDIATE
VICINITY OF THE LLCC. A RECENT OBSERVATION FROM WILLIS ISLAND INDICATES
SOUTHERLY WINDS AT 8 KNOTS AND A SLP OF 1006MB. A 052325Z ASCAT-B PASS
REVEALED AN ELONGATED AREA OF TURNING EXTENDING FROM HEAR BOUGANVILLE
REEF TO SOUTHEAST OF WILLIS ISLAND. THE LLCC IS PLACED IN THE
NORTHWESTERN END OF THIS TROF. WINDS UP TO 20-25 KTS ARE PRESENT ALONG
THE NORTHERN SIDE THE TROF, WITH 15-20 KTS ALONG THE SOUTHERN SIDE.
ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT
WITH LOW VERTICAL WIND SHEAR (VWS) OF 5-10 KNOTS, MODERATE UPPER-LEVEL
OUTFLOW, AND WARM SEA SURFACE TEMPERATURES (SST) OF 29-30C. GLOBAL
MODELS SHOW MODERATE AGREEMENT REGARDING DEVELOPMENT; HOWEVER, THE GFS
INDICATES MORE RAPID INTENSIFICATION THAN OTHER DETERMINISTIC MODELS.
DESPITE THESE DIFFERENCES IN SPEED, THERE IS HIGH CONFIDENCE IN A
QUASI-STATIONARY TRACK OVER THE NEXT 48 HOURS. 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.

Tropical Low 12U
Moderate risk of a tropical cyclone from Thursday night off the northeast Queensland coast.
A broad monsoon low (12U) is slowly starting to form to the northeast of Willis Island. It will take some time for this low to become an established circulation.
Tropical Low 12U is likely to be slow moving at first, before moving west or southwest towards the northeast Queensland coast late in the week.
The low should gradually develop, and the risk of a tropical cyclone increases to Moderate (25-40%) from Thursday night.
From Sunday, the risk of a tropical cyclone decreases back to Low as 12U is more likely to have moved over land. During next week 12U may move over Gulf of Carpentaria waters where it has a Low chance of becoming a tropical cyclone.
There is potential for increased risk of rain, flooding, wind and marine hazards for residents in northeast Queensland. Rain and flooding risks could continue after 12U has moved over land. Residents in these areas should monitor forecasts for updates.
If 12U moves towards western Queensland or the southern Gulf of Carpentaria, it is likely that the second tropical low (13U) will have already weakened.

Headline:
Increasing chance of a tropical cyclone developing off the northeast Queensland coast over the next few days.
Areas affected:
Warning zone: None.
Watch zone: None.
Cancelled zones: None.
Details of Tropical Low 12U at 4:00 pm AEST:
Intensity: tropical low, sustained winds near the centre of 65 kilometres per hour with wind gusts to 95 kilometres per hour.
Location: within 95 kilometres of 15.0 degrees South, 150.0 degrees East , 500 kilometres east northeast of Cairns and 580 kilometres northeast of Townsville .
Movement: slow moving .
A tropical low (12U) is developing in the Coral Sea, north of Willis Island. The system is expected to move slowly northwest initially, before turning southwest and moving towards the northeast Queensland coast during Friday.
There is an increased chance that tropical low 12U may develop into a tropical cyclone during Friday night or Saturday as it approaches the coast.
Hazards:
A Severe Weather Warning is current for heavy to locally intense rainfall and damaging winds about the northeast tropical Queensland coast. If the risk of a tropical cyclone increases further, then gales with wind gusts to 120 km/h may develop during Saturday initially about exposed coastal parts between Port Douglas and Proserpine, including Cairns and Townsville.
Recommended Action:
Residents along the northeast Queensland coast should monitor forecasts, warnings, and updates from the Bureau of Meteorology.
