REMARKS:
Tropical Cyclone Laurence crossed the Kimberley coast northeast of Derby as a
small but intense system and has since weakened over land. Dvorak: shear pattern
gives DT of 3.5, PAT = 3.0 and CI held at 3.5. Mean surface winds estimated at
35 knots due to the system being over land.
Although weakening, heavy rainfall continues with 24 hour rainfall totals of
about 300mm being reported along the cyclone track.
Laurence is expected to weaken further and be slow moving in the short term as
it tracks over land on a general south to southwest track. In the longer term a
westerly track seems likely as a mid-level ridge develops to the south. The
system should move off the west Kimberley coast in 36 to 48 hours time and
redevelop into a tropical cyclone over warm ocean waters and a favourable upper
level wind pattern.

At 8:00 pm WST Ex-Tropical Cyclone Laurence was estimated to be
20 kilometres north of Derby and moving
west northwest at 7 kilometres per hour.
Ex-Tropical Cyclone Laurence has begun to move westwards towards the west
Kimberley coast. A period of squally weather is expected in Derby as the low
moves close by this evening.
The low is expected to move off the west Kimberley coast during Saturday. It is
then likely to reintensify and GALES could develop along the west Kimberley
coast between Cape Leveque and Bidyadanga, including Broome, on Saturday evening
or on Sunday. As the system moves westwards GALES could extend further down the
coast to Wallal late on Sunday.
Record daily rainfall totals have been recorded at Kimberley Downs and Napier
Downs in the west Kimberley, but the heaviest falls have fallen outside the
Fitzroy River catchment. HEAVY RAIN is expected to continue over parts of the
northwest Kimberley overnight.
FESA-State Emergency Service advises that there are no community alerts at
present.
Communities in the western Kimberley and northern Pilbara should listen for the
next advice.
Details of Ex-Tropical Cyclone Laurence at 8:00 pm WST:
.Centre located near...... 17.1 degrees South 123.6 degrees East
.Location accuracy........ within 35 kilometres
.Recent movement.......... towards the west northwest at 7 kilometres per hour
.Wind gusts near centre... 85 kilometres per hour
.Severity category........ below cyclone intensity
.Central pressure......... 998 hectoPascals
The next advice will be issued by 12:00 am WST Saturday 19 December.

REMARKS:
Ex-TC Laurence has begun to track steadily westwards toward the coast. This
motion is likely to continue under the influence of low level flow until the
system moves off the west Kimberley coast. As it moves off the coast vertical
wind shear is expected to be light and with a well developed low to mid level
circulation and a moist profile through depth the system is expected to
redevelop once over open water. The system is likely to move offshore during
Saturday. Once it redevelops it will experience a weak deep layer steering
pattern and motion will slow.
Rainfall totals near the centre have been over 200mm in the last 24 hours, with
isolated heavier falls. Most rain fell in the Leonard River catchment rather
than the Fitzroy River catchment.

Re: TIMOR SEA : EX-TROPICAL CYCLONE LAURENCE (06S)
Cool system. Hanging together in that tropical moisture. Good rain for that dry part of Australia.
