REMARKS:
Tropical Cyclone Trevor has continued to become organised with several deep
convective bands wrapping around the centre in the last 6 hours. Latest
satellite images show deep convection now covering the centre with a possible
CDO developing.

Position is good based on enhanced animated rapid scan VIS imagery and hint of
the a circulation centre appearing on Weipa radar.

Dvorak analysis is based on a tightest curved band wrapping 0.8 yielding a
DT=3.5. MET agrees with development at 1.5 rate per day. ADT is near 3.0 and
SATCON estimate is 60 knots [1-minute average].

The cyclone continues to be steered by a weakening mid-level ridge to the east,
while a stronger middle level ridge is now building across the main land to the
south. This will maintain a dominant east to northeast steering over the system.

Overall synoptic environment has remained very favourable in the last 24 hours,
enabling Trevor to rapidly develop from a T2.0 to a T3.5. Given the favourable
conditions into the convective diurnal cycle [overnight], further
intensification is expected.

At this rate, Trevor could reach a high end category 3 cyclone before it crosses
the coast on Tuesday evening. There is a risk of further intensification to a
category 4 even, if the cyclone moves slower than its forecast speed.

Trevor is expected to weaken to a low or a marginal category 1 system as it
crosses the Peninsula and into the Gulf of Carpentaria during Wednesday. The
conditions for redevelopment in the Gulf of Carpentaria are similar to that of
the east coast. Hence, Trevor is expected to redevelop or intensify quickly as
it moves over water towards the southwestward.

TROPICAL CYCLONE ADVICE NUMBER 9
Issued at 4:53 pm EST on Monday 18 March 2019

Headline:
Tropical Cyclone Trevor is rapidly intensifying and expected be a category 3 cyclone tomorrow morning.A Cyclone Watch has been extended to the western Peninsula coast.

Areas Affected:
Warning Zone
Orford Ness to Cooktown.

Watch Zone
Cape York to Pormpuraaw.

Cancelled Zone
Cooktown to Cape Tribulation and Orford Ness to Cape York.

Details of Tropical Cyclone Trevor at 4:00 pm AEST:
Intensity: Category 2, sustained winds near the centre of 95 kilometres per hour with wind gusts to 130 kilometres per hour.

Location: within 30 kilometres of 12.5 degrees South 145.3 degrees East, estimated to be 220 kilometres east of Lockhart River and 370 kilometres east of Weipa.

Movement: west southwest at 6 kilometres per hour.

Tropical Cyclone Trevor continues to move slowly towards the eastern Cape York Peninsula coast. It is expected to intensify to a category 3 before crossing the coast near Lockhart River on Tuesday evening. Tropical Cyclone Trevor may weaken as it crosses the northern Peninsula during Tuesday night before entering the Gulf of Carpentaria later on Wednesday, where it will reintensify into a tropical cyclone.

Hazards:
GALES, with gusts in excess of 90 km/h, are expected to develop between Cape Grenville and Cooktown tonight. These GALES may extend north to Orford Ness during Tuesday, if the cyclone takes a more northerly track.

DESTRUCTIVE WINDS, with gusts in excess of 125 km/h are possible between Cape Grenville and Coen from Tuesday afternoon as the cyclone approaches the coast.

The VERY DESTRUCTIVE CORE of Tropical Cyclone Trevor, with extreme gusts up to 205 km/h may occur near the centre as the cyclone makes landfall on Tuesday evening.

GALES are expected to extend inland over the Peninsula on Tuesday night as the cyclone moves inland. GALES may develop along the western Peninsula coast between Thursday Island and Pormpuraaw during Wednesday as Trevor reintensifies in the Gulf of Caprentaria.

ABNORMALLY HIGH TIDES are expected on Tuesday and Wednesday's morning high tides for far northeast Queensland coast, north of Port Douglas.

As the cyclone crosses the coast, a storm tide is expected between Orford Ness and Cape Flattery. Large waves may produce minor flooding along the foreshore. People living in these areas are likely to be affected by flooding and should take measures to protect their property as much as possible and be prepared to help their neighbours.

HEAVY RAINFALL, which may lead to flash flooding, is forecast to develop across far north Queensland over the next few days. A Flood Watch has been issued for catchments north of Cairns to Kowanyama.

Recommended Action:
People between Orford Ness and Cooktown, including Lockhart River and Coen, should immediately commence or continue preparations, especially securing boats and property, using available daylight hours.

People between Cape York and Pormpuraaw on western Peninsula, should consider what action they will need to take if the cyclone threat increases, and listen to the next advice at 8pm AEST.

- Information is available from your local government.

- For cyclone preparedness and safety advice, visit Queensland's Disaster Management Services website (www.disaster.qld.gov.au).

- For emergency assistance call the Queensland State Emergency Service (SES) on 132 500 (for assistance with storm damage, rising flood water, fallen trees on buildings or roof damage).

Next Advice:
The next advice will be issued by 8:00 pm AEST Monday 18 March.

This warning is also available through TV and Radio Broadcasts; the Bureau's website at www.bom.gov.au or call 1300 659 212. The Bureau and the State Emergency Service would appreciate this warning being broadcast regularly.

REMARKS:
Tropical low 20U [now tropical cyclone Trevor] has continued to develop during
the past 6 hours, and now exhibits a central dense overcast with a cold comma
and peripheral banding. Position fair based on recent microwave passes and
extrapolation.

Dvorak analysis is based on a curved band pattern with an average 0.6 to 0.7
wrap over the past three hours. DT is 3.0. MET is 2.5 based on a 24 hour D
trend. PT is 3.0 based on the improved cloud structure. Final T is 3.0. ADT
guidance suggests FT 2.8 with Vmax [1 minute] 41 knots. Intensity is analysed at
35 knots [10 minute mean].

The system will continue to be steered WSW by a weak mid-level ridge to the east
in the short term. In the medium term, a new ridge will build under the system
and steer it more westward. NWP guidance is reasonably consistent on this
prognosis.

Vertical wind shear is low along the projected track, with the subtropical jet
well to the south. SSTs are favourable and upper outflow is reasonably good to
the south. Development at the standard rate is forecast which would see the
system reach at least category 2 before making landfall on the eastern Cape York
Peninsula coast late on Tuesday, though a crossing at category 3 cannot be ruled
out.

In the longer term, the system is likely to move into the Gulf of Carpentaria
around mid-week. Conditions for development are expected to remain favourable
and the system is likely to redevelop into a tropical cyclone in the Gulf.

Issued at 4:46 am EST on Monday 18 March 2019

Headline:
Tropical cyclone Trevor has formed in the northern Coral Sea.

Areas Affected:
Warning Zone
Cape Grenville to Cape Flattery, including Coen and Lockhart River.

Watch Zone
Cape York to Cape Grenville and Cape Flattery to Cape Tribulation (including Cooktown), including adjacent inland areas.

Cancelled Zone
None.

Details of Tropical Cyclone Trevor at 4:00 am AEST:
Intensity: Category 1, sustained winds near the centre of 65 kilometres per hour with wind gusts to 95 kilometres per hour.

Location: within 75 kilometres of 12.4 degrees South 146.1 degrees East, estimated to be 305 kilometres east of Lockhart River and 500 kilometres north of Cairns.

Movement: west southwest at 10 kilometres per hour.

Tropical cyclone Trevor, category 1, has formed in the northern Coral Sea east of Cape York Peninsula.

Tropical cyclone Trevor is expected to move in a west-southwest direction towards the Cape York Peninsula coast. It is expected to continue intensifying, and should reach category 2 before crossing the eastern Cape York Peninsula coast later on Tuesday.

Hazards:
GALES, with gusts in excess of 90 km/h, are expected to develop between Cape Grenville and Cape Flattery on Monday night. These GALES may extend north to the Torres Strait Islands and south to Cape Tribulation, including Cooktown, on Tuesday.

DESTRUCTIVE WINDS, with gusts in excess of 125 km/h, may occur as the centre of the cyclone makes landfall on the eastern Cape York Peninsula coast later on Tuesday.

As the cyclone crosses the coast, ABNORMALLY HIGH TIDES are expected about the far north Queensland coast. Large waves are likely along the beachfront.

HEAVY RAINFALL, which may lead to flash flooding, is forecast to develop across far north Queensland over the next few days.

Recommended Action:
People between Cape Grenville and Cape Flattery, including Lockhart River and Coen, should immediately commence or continue preparations, especially securing boats and property, using available daylight hours.

REMARKS:
A Tropical Low is located to the south of the PNG mainland. Centre location is
fair based on VIS and microwave animation. This has been confirmed by the latest
ASCAT pass. A small deep convective blob near centre gives a DT=1.5 with deeper
convection located in a band further to the northwest. Current Intensity is
based on MET=2.0=PT.

The ASCAT pass shows a decent low level cross equatorial flow feeding into the
low with gales located near centre in the NE quadrant. The low is located in a
low vertical wind shear zone under an upper high with good upper level outflow
to the west and south, aided by an upper cut-off low moving eastwards in the far
south. Sea surface temperatures in the northwest Coral Sea are around 30
degrees.

The low is showing reasonably good organisation but missing deep convection near
centre at present. However, the favourable environment will lead to the low
developing into a tropical cyclone in the next 24 hours. Further intensification
to category 2 is possible.

The low is likely to be steered by the weak mid-level ridge located to its east
in the short term and then by a stronger ridge building over Australia as the
cut-off low in the far south moves away. Overall, a west-southwest movement
would be favoured throughout its life-time. On this path, the cyclone would
cross the Cape York Peninsula coast and weaken due to land effects during early
week.

Given the favourable conditions persisting in the longer term, there is a good
chance that the cyclone may redevelop once it moves into the southern Gulf of
Carpentaria by mid to late week.
