REMARKS:
Dvorak: The 0030 UTC MTSAT EIR image showed a ragged eye. E no 5.0, E adj -0.5
with DT of 4.5. This feature subsequently weakened. Recent visible imagery
showed tight banding with between 1.2 and 1.3 wrap giving DTs of 4.0.

MET was 4.5 based on developing trend and PAT was also 4.5. So FT/CI set to 4.5.

NW shear is expected to increase late Monday and is likely to adversely affect
the circulation so weakening is expected from late Monday onwards. UW-CIMMS at
0600 UTC indicated NW shear of about 15 knots. [At 0000 UTC, NW shear of about 9
knots].

Motion should remain slow with a general southward track as a mid-level trough
passes to the south overnight. From Tuesday a westerly track is expected as a
mid-level ridge develops in the wake of the trough. The extent of the westerly
track is dependent upon weakening/shearing processes.

The cyclone is likely to remain over open waters and does not pose a risk to
island or coastal communities.

REMARKS:
050900Z POSITION NEAR 16.1S 92.0E.
TROPICAL CYCLONE (TC) 23S (ROBYN), LOCATED APPROXIMATELY 370 NM
SOUTHWEST OF THE COCOS ISLANDS, AUSTRALIA, HAS TRACKED EAST-
SOUTHEASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTI-
SPECTRAL SATELLITE IMAGERY SHOWS DEEP CONVECTION HAS DECREASED OVER
THE PAST 12 HOURS HOWEVER, THE LLCC REMAINS WELL ORGANIZED BASED ON A
050250Z ASCAT PASS SHOWING THE STRONGEST WINDS LOCATED IN THE SOUTH-
WESTERN QUADRANT OF THE LLCC, AT 45 TO 50 KNOTS. THE CURRENT INTEN-
SITY OF 60 KNOTS IS BASED ON DVORAK INTENSITY ESTIMATES RANGING FROM
55 TO 75 KNOTS. UPPER LEVEL ANALYSIS INDICATES THE MIDLATITUDE SHORT-
WAVE TROUGH FROM THE PREVIOUS FORECAST CONTINUES TO TRACK EASTWARD,
AND IS CURRENTLY LOCATED TO THE SOUTH OF TC 23S. THE TROUGH CONTINUES
TO CREATE STRONG WESTERLY FLOW POLEWARD OF TC 23S HELPING TO VENT THE
SYSTEM. AS ROBYN MOVES SOUTHEASTWARD IT HAS STARTED TO MOVE INTO A
HIGHER VERTICAL WIND SHEAR (VWS) ENVIRONMENT AND IS NOW POLEWARD OF
THE SUBTROPICAL RIDGE (STR) AXIS. THE MIDLATITUDE TROUGH HAS WEAKENED
THE STR AND WILL KEEP ROBYN SLOWLY TRACKING TO THE SOUTHEAST OVER THE
NEXT 24 HOURS UNTIL A DEVELOPING MIDLATITUDE STR BUILDS TO THE SOUTH
CAUSING A SHIFT IN THE TRACK TO THE WEST-SOUTHWEST AND A TRACK SPEED
INCREASE. INCREASING VWS WILL BEGIN TO QUICKLY WEAKEN TC 23S WITH
DISSIPATION EXPECTED BY TAU 72. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
050600Z IS 18 FEET. NEXT WARNINGS AT 052100Z AND 060900Z.//

The problem is... Will Robyn manage to get another name from Mauritius?

Superb agreement between the agencies with regards to track, pretty much identical in fact!

Looks around 55-60kts, convection is becoming increasingly shallow from the looks of the IR but it still looks decent enough though.

REMARKS:

Tropical Cyclone Robyn has started to weaken as it enters an environment of
stronger wind shear. UW-CIMMS at 1800 UTC indicated NW shear of about 15 knots.
A Dvorak analysis yields a T-number of 3.5 based on a shear pattern with the low
level centre located less than 1/3 of a degree into the strongest temperature
gradient.

Motion has remained slow in the last 12 hours as a mid-level trough passes to
the south. The cyclone should start taking a westerly track during Tuesday as a
mid-level ridge develops in the wake of the trough. The extent of the westerly
track is dependent upon weakening/shearing processes.

The cyclone is likely to remain over open waters and does not pose a risk to
island or coastal communities.

REMARKS:
Tropical Cyclone Robyn is weakening under increasing northwesterly wind shear
[now more than 20 knots]. Deep convection is now displaced more than a degree
southeast of the LLCC.

Dvorak analysis: DT=2.0 [shear pattern LLCC >3/4 degree from temperature
gradient], FT contrained to 2.5 and CI held at 3.0.

Robyn has moved slowly in the last 18 hours as higher level northwesterly
steering flow competes with lower level westerly flow. As Robyn continues to
shear, the westerly steering should dominate associated with a strengthening
ridge to the southwest in the wake of an amplifying mid-level trough off the
Western Australian coast.

While Robyn is likely to weaken below cyclone intensity in the next 12 hours or
so, gale-force winds should persist on the southern side assisted by
translation and the strong ridge to the south.

REMARKS:
Ex-Tropical Cyclone Robyn has weakened under northwesterly wind shear of about
20 knots. Deep convection is now displaced more than a degree southeast of the
LLCC.

Dvorak analysis: DT < 1.0 [shear pattern LLCC >1 1/4 degree from deep
convection], FT constrained to 2.0 and CI held higher at 2.5. Although this
would suggest maximum winds of 30 knots, intensity is estimated at 35 knots
based on the strong E./SE gradient south of the centre.

Despite the weakening, gale-force winds should persist on the southern side
assisted by translation and the strong ridge to the south. See Shipping Warning
for further details.

The system is now moving to the northwest under the influence of ridge building
to the south in the wake of a deep trough off the Western Australian coast. The
system should be steered to the west in the forecast period and move west of 90E
on Wednesday.
