REMARKS:
042100Z POSITION NEAR 13.2S 131.8E.
TROPICAL CYCLONE (TC) 10S (HELEN), LOCATED APPROXIMATELY 45 NM SOUTH-
SOUTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED EASTWARD AT 12 KNOTS OVER
THE PAST 06 HOURS. THE CURRENT STORM POSITION AND INTENSITY ARE BASED
ON DVORAK SATELLITE FIXES FORM PGTW AND ABRF, RADAR IMAGERY FROM
DARWIN, AND SYNOPTIC OBSERVATIONS FROM THE AREA AFFECTED BY THE STORM.
STRONG LOW TO MID-LEVEL WESTERLY FLOW ASSOCIATED WITH NEAR-EQUATORIAL
RIDGING TO THE NORTH OF THE STORM REMAINS THE PRIMARY STEERING INFLU-
ENCE. THIS STEERING RIDGE IS EXPECTED TO REMAIN IN PLACE THROUGH THE
FORECAST PERIOD, RESULTING IN A GENERALLY EASTWARD TO SOUTHEASTWARD
TRACK. TC 10S WILL WEAKEN OVER LAND BEFORE REEMERGING OVER WARM WATER
IN THE GULF OF CARPENTARIA AROUND TAU 18. THE STORM IS MOVING EAST OF
A SYNOPTIC-SCALE UPPER LEVEL ANTICYCLONE CENTER AND WILL EXPERIENCE
INCREASING WESTERLY VERTICAL WIND SHEAR AS A RESULT. PASSAGE OVER LAND
DURING THE NEXT 18 HOURS WILL LIKELY PREVENT THE STORM FROM DEVELOPING
A STRONG OUTFLOW BUFFER AGAINST THIS INCREASING VERTICAL WIND SHEAR.
THEREFORE, THE STORM IS EXPECTED TO INTENSIFY SLOWLY AS IT CROSSES
INTO THE GULF OF CARPENTARIA. THE SYSTEM WILL AGAIN MAKE LANDFALL OVER
THE CAPE YORK PENINSULA JUST PRIOR TO TAU 48 AND BEGIN DISSIPATING
THEREAFTER. THE AVAILABLE NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT
WITH BOTH THE TRACK AND INTENSITY FORECAST. NEXT WARNINGS AT 050900Z
AND 052100Z.

Looks like it will regain cyclone intensity as it returns to water...

My guess is 55 kt (1-min) for the landfall intensity.

moving east at 25 kilometres per hour.

EX-TROPICAL CYCLONE Helen continues to move steadily east across Arnhem Land and

Carpentaria early on Sunday morning.

GALES with gusts to 100 kilometres per hour are expected to affect coastal and
island communities between Nhulunbuy and Port Roper on Sunday morning.

GALES with gusts to 100 kilometres per hour are expected to develop between
Weipa and Karumba late Sunday.

GALES may develop along the coast between Port McArthur [NT] and Karumba [Qld]
on Monday.

Heavy rain is expected to cause flooding of low-lying areas over the eastern Top
End.

Note that severe weather warnings remain current for Top End areas and for the
eastern Gulf of Carpentaria and Torres Strait in Queensland.

FLOOD THREAT ADVICE
Issued by the BUREAU OF METEOROLOGY, DARWIN
at 1047 CST Saturday 5 JANUARY 2008

AREA INVOLVED
Top End, Gulf Country and northern Victoria River districts.

RAINFALL SUMMARY
Widespread falls of 20 - 100 mm with falls of 100 - 200 mm over the central and
western Top End.

WEATHER SUMMARY
The monsoon trough lies over the Top End with an active monsoon flow to its
north. Ex-Tropical Cyclone "Helen" is currently near the township of Adelaide
River and moving east across the Top End. As a tropical Low it is expected to
move into the Gulf of Carpentaria on Sunday and redevelop to Tropical Cyclone
intensity.

FORECAST for the rest of today and Sunday
Scattered falls of 50mm in showers and storms over the Top End and Gulf Country.
Rain and locally heavy falls over the Top End will produce falls of up to 100mm
in bands of rain into the Low. Heavier falls could occur over central parts of
the Top End and then Arnhem Land and the Gulf Country as the Low moves further
east. Ex-Tropical Cyclone Helen is expected to redevelop in the Gulf of
Carpentaria on Sunday. Falls may lead to significant stream rises and flooding
of low-lying areas. Rainfall is expected to ease over the northern Victoria
River District from today and over the western Top End from Sunday.

OUTLOOK for Monday and Tuesday
Dependent on the movement of Ex-Tropical Cyclone Helen widespread showers and
storms could still affect the eastern Top End and Gulf Country with falls of
about 30 - 50mm. Heavy falls of 100mm or more are possible near the Low/Cyclone,
most likely in the Gulf region. These falls will lead to significant stream
rises and flooding of low lying areas.

NEXT ADVICE
Around 11 am Sunday.

DARWIN Regional Forecasting Centre.
