IDW10800

Tropical Cyclone Outlook for the Western Region
Issued at 2:22 pm WST on Monday 8 January 2018
for the period until midnight WST Thursday 11 January 2018.

Existing Cyclones in the Western Region:
Nil.

Potential Cyclones:

A tropical low lies over the northern Kimberley, near 15.3S 127.4E at 2pm WST. The low is forecast to track to the west south west, moving offshore from the northwest Kimberley coast Tuesday morning. Once offshore, it should strengthen and is likely to develop into a tropical cyclone during Wednesday or Thursday. On Thursday, it is forecast to take a more southerly track and possibly cross the far western Kimberley or eastern Pilbara coast on Friday. There remains a chance it takes a more westerly track and crosses the coast further west along the Pilbara coast later Friday or over the weekend.


Likelihood of this system being a tropical cyclone in the Western Region on:
Tuesday:Low
Wednesday:High
Thursday:High

REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 16.0S 127.2E IS NOW LOCATED NEAR 15.8S 125.9E , APPROXIMATELY 247 NM EAST-NORTHEAST OF BROOME, AUSTRALIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC) WITH FORMATIVE BANDING OVER THE SOUTHWESTERN PERIPHERY. A 090045Z AMSU METOP-B 89GHZ IMAGE SHOWS CURVED, DEEP CONVECTIVE BANDING OVER THE SOUTHERN SEMI-CIRCLE WRAPPING INTO LLCC. RECENT ASCAT IMAGERY REVEALS AN AREA OF 20-25 KNOT WINDS IN THE NORTHEASTERN QUADRANT. UPPER LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT WITH MODERATE
(15-20 KNOTS) VERTICAL WIND SHEAR WITH RADIAL OUTFLOW. DYNAMIC MODELS ARE IN GOOD AGREEMENT THAT 96S WILL CONTINUE TO STRENGTHEN INTO A TROPICAL CYCLONE BY TAU 24 AS THE DISTURBANCE TRACKS OVER WATER.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 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 HIGH.

For those of you who may not be familiar with Australia tropical cyclone categories, a category 3 cyclone is equivalent to a Saffir-Simpson category 1 hurricane.

TROPICAL CYCLONE 05S (FIVE), LOCATED APPROXIMATELY 75 NM
NORTHEAST OF BROOME, AUSTRALIA, HAS TRACKED WEST-NORTHWESTWARD AT
06 KNOTS OVER THE PAST SIX HOURS. THE JOINT TYPHOON WARNING CENTER
HAS ASSESSED THAT DESPITE TROPICAL DEPRESSION 05S BEING LOCATED OVER
LAND, INTENSIFICATION TO BASIN WARNING CRITERIA (35 KNOTS) WILL
OCCUR WITHIN THE NEXT TWELVE HOURS ONCE THE SYSTEM TRACKS OVER WATER
THEREFORE JUSTIFYING THE ISSUE OF A TROPICAL CYCLONE WARNING.
ANIMATED MULTI-SPECTRAL SATELLITE IMAGERY DEPICTS A PARTIALLY
EXPOSED, BROAD LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING
CONVECTION PREDOMINANTLY IN THE NORTHWESTERN QUADRANT. A 092255Z
89GHZ AMSU MICROWAVE IMAGE CONFIRMS DEEP CONVECTION NORTHWEST OF THE
LLCC AND ALSO SHOWS WEAK BANDING LOCATED IN THE NORTHERN SEMI-
CIRCLE. THE INITIAL POSITION IS PLACED WITH LOW CONFIDENCE BASED ON
THE PARTIALLY EXPOSED LOW LEVEL AND THE AUSTRALIAN BUREAU OF
METEOROLOGY ANIMATED RADAR LOOP. THE INITIAL INTENSITY OF 30
KNOTS IS ON SURFACE OBSERVATIONS NEAR THE CENTER OF THE SYSTEM
SHOWING 25 TO 27 KNOTS. ENVIRONMENTAL ANALYSIS SHOWS THAT THE SYSTEM
IS IN AN AREA OF LOW VERTICAL WIND SHEAR (10-15 KNOTS) AND ONCE IT
TRACKS OVER THE INDIAN OCEAN WEST OF AUSTRALIA, IT WILL BE IN AN
AREA OF VERY WARM (30-31 CELSIUS) SEA SURFACE TEMPERATURES. TD 05S
IS FORECAST TO TRACK TO THE WEST OVER THE NEXT TWELVE HOURS, EXITING
OVER WATER AROUND TAU 6. ONCE OVER WATER THE SYSTEM WILL QUICKLY
INTENSIFY. THE TRACK DIRECTION IS FORECAST TO SHIFT TO THE SOUTHWEST
AFTER TAU 12 AS THE SYSTEM TRACKS ALONG THE WESTERN EXTENT OF AN
EXTENSION OF THE SUBTROPICAL RIDGE LOCATED OVER EASTERN AUSTRALIA.
THE SYSTEM IS FORECAST TO MAKE LANDFALL SOUTH OF BROOME, AUSTRALIA
AROUND TAU 36. ONCE OVER LAND, THE SYSTEM WILL GRADUALLY WEAKEN,
MAINTAINING TROPICAL STORM STRENGTH INTENSITY THROUGH TAU 60 DUE TO
HIGH MOISTURE ALONG THE OVERLAND TRACK. THE SYSTEM IS FORECAST TO
DISSIPATE OVERLAND BY TAU 72. DYNAMIC MODEL GUIDANCE IS IN FAIR
AGREEMENT, VARYING ON THE SPEED OF THE TURN MEANING THAT SOME MODELS
HAVE THE SYSTEM TRACKING ENTIRELY OVERLAND WHILE OTHERS TRACK
FARTHER WEST OVER WATER. DUE TO THE LOW CONFIDENCE IN THE INITIAL
POSITION AND THE VARIATIONS IN THE MODEL GUIDANCE, THERE IS OVERALL
LOW CONFIDENCE IN THE JTWC TRACK FORECAST.

Western Australia
Tropical Cyclone Warning Centre

Media: The Standard Emergency Warning Signal should NOT be used with this warning.

TOP PRIORITY FOR IMMEDIATE BROADCAST
TROPICAL CYCLONE ADVICE NUMBER 12
Issued at 11:47 am WST on Wednesday 10 January 2018

Headline:
A tropical cyclone may form off the west Kimberley coast overnight or Thursday morning. There is still a risk of a severe tropical cyclone impacting northern WA late Thursday or Friday.

Areas Affected:
Warning Zone
Kuri Bay to Wallal Downs, including Broome.

Watch Zone
Wallal Downs to Port Hedland, as well as remaining inland parts of the northeast Pilbara, including Marble Bar and Telfer and the far western Kimberley.

Cancelled Zone
None.

Details of Tropical Low at 11:00 am AWST:
Intensity: Tropical Low, sustained winds near the centre of 45 kilometres per hour with wind gusts to 85 kilometres per hour.

Location: within 55 kilometres of 16.4 degrees South 122.6 degrees East, estimated to be 150 kilometres northwest of Derby and 175 kilometres north northeast of Broome.

Movement: west at 10 kilometres per hour.

A tropical low is now offshore from the west Kimberley coast and may develop into a tropical cyclone overnight or during Thursday. There is a risk of a severe tropical cyclone impact over the far western Kimberley and far eastern Pilbara late Thursday or Friday. There is some uncertainty in the forecast track, and it is still possible the system could impact coastal parts of the central and western Pilbara during Friday and Saturday.

Hazards:
GALES with gusts to 100 kilometres per hour may develop in coastal parts between Kuri Bay and Bidyadanga, including Broome, overnight or early Thursday morning. GALES may extend to areas between Bidyadanga and Wallal Downs during Thursday morning, and to areas between Wallal Downs and Port Hedland later on Thursday or early Friday.

DESTRUCTIVE winds with gusts to 130 kilometres per hour may develop in coastal parts between Beagle Bay and Wallal Downs (including Broome) on Thursday if the system develops quickly and is close enough to the coast.

Heavy rainfall is expected over the northwest and west Kimberley coast, extending to the far eastern Pilbara during Thursday. Widespread daily rainfall totals of around 50 to 150 mm are expected with isolated heavier falls of 150-300 mm possible. Flood Watches and Warnings are current. Please refer to http://www.bom.gov.au/wa/warnings/ for further details.

REMARKS:
Tropical Low 09U was located using visible imagery and nearby surface
observations.

The system is now moving over open waters and has shown signs of development.

Dvorak initial classification of 1.5 was made at 0000 UTC. Curved band wrap on
EIR and VIS of around 0.2 to 0.3 would yield DTs of 1.5 to 2.0.

Intensity set to 25 knots.

Conditions are favourable for development with SSTs around 30/31C, favourable
ocean heat potential and low wind shear. UW-CIMSS at 0300 UTC indicates that the
system is close to the shear ridge. There is some equatorward and poleward
outflow.

09U may develop into a tropical cyclone overnight or during Thursday morning.
Generally W/SW motion should continue today. During Thursday an upper level
trough to the south will improve outflow and steer the system towards the S/SW
towards the coast as it strengthens. Intensification into a severe category 3
cyclone is possible prior to landfall late Thursday or during Friday. Intensity
may be constrained by the amount of time over open waters.

The range of tracks from global NWP models have an initial W/SW motion then S/SW
motion. A few NWP ensemble members and NWP global models have the system
tracking roughly parallel to the Pilbara coast on Friday and Saturday. This is
due to the interaction of the system with the upper level trough and mid level
ridge. The uncertainty area accounts for this scenario.

Once inland the system will weaken, however, gales may persist in the NE and SE
quadrants due to the pressure gradient between the system and a ridge to the
south.

The next bulletin for this system will be issued by: 10/1330 UTC by Perth TCWC.

Note that this is 10-minute sustained winds. A category 3 on the BOM scale can be equivalent to a major hurricane if the winds are 85 kt 10-minute sustained.

The low is currently predicted to become a 75 kt system which would be a category 2 on the Saffir-Simpson scale.

TOP PRIORITY FOR IMMEDIATE BROADCAST
TROPICAL CYCLONE ADVICE NUMBER 19
Issued at 8:52 am WST on Thursday 11 January 2018

Headline:
Tropical Cyclone Joyce has formed off the west Kimberley coast and is expected to intensify today while moving in a southwesterly direction. There is a risk of a severe tropical cyclone impacting the Pilbara or far west Kimberley coast during Friday, or early on Saturday.

Areas Affected:
Warning Zone
Cape Leveque to De Grey, including Broome, as well as remaining inland parts of the far western Kimberley and far northeast Pilbara.

Watch Zone
De Grey to Dampier, including Port Hedland, Karratha and Dampier, as well as remaining inland parts of the central and eastern Pilbara, including Nullagine, Marble Bar and Telfer

Cancelled Zone
None.

Details of Tropical Cyclone Joyce at 8:00 am AWST:
Intensity: Category 1, sustained winds near the centre of 65 kilometres per hour with wind gusts to 95 kilometres per hour.

Location: within 35 kilometres of 16.8 degrees South 121.7 degrees East, estimated to be 140 kilometres north northwest of Broome and 140 kilometres west southwest of Cape Leveque.

Movement: southwest at 6 kilometres per hour.

The uncertainty in the forecast track means that it is still possible the system could impact coastal parts of the central and western Pilbara late on Friday or during Saturday.

Hazards:
GALES with gusts to 100 kilometres per hour are possible today between Cape Leveque and Broome. GALES may extend to areas between Broome and Wallal Downs during Thursday afternoon and evening, and to areas between Wallal Downs and Port Hedland on Friday. If the system tracks further to the west then GALES are possible in areas between Port Hedland and Whim Creek.

DESTRUCTIVE winds with gusts to 130 kilometres per hour may develop in coastal parts between Beagle Bay and Wallal Downs, including Broome, later on Thursday if the system is close enough to the coast. DESTRUCTIVE winds may extend to Pardoo Roadhouse during Friday.

VERY DESTRUCTIVE winds with gusts to 180 kilometres per hour are possible near the centre of the system on Friday, if it develops into a severe tropical cyclone.

Tides will be higher than expected between Cape Leveque and Pardoo Roadhouse.Heavy rainfall is expected over the northwest and west Kimberley coast, extending to the far eastern Pilbara during Thursday. Widespread daily rainfall totals of around 50 to 150 mm are expected with isolated heavier falls of 150-300 mm possible. Flood Watches and Warnings are current. Please refer to http://www.bom.gov.au/wa/warnings/ for further details.

Recommended Action:
DFES advises of the following community alerts:

YELLOW ALERT: People in, near or between Cape Leveque and Bidyadanga, including Broome and Bidyadanga need to take action and get ready to shelter from a cyclone.

BLUE ALERT: People in, near and between Bidyadanga and Port Hedland, including Port Hedland, South Hedland, Marble Bar and nearby communities, need to prepare for cyclonic weather and organise an emergency kit including first aid kit, torch, portable radio, spare batteries, food and water.

Next Advice:
The next advice will be issued by 12:00 pm AWST Thursday 11 January.
