REMARKS:
Tropical low [10U] is a small system that has shown rapid development over the
last 6-12 hours.

Position was analysed using microwave and satellite imagery, with gmi/ssmis at
20:10 UTC giving a good fix. Curvature is increasing for 10U, with Dvorak
giving DT=2.5. FT/CI are also set at 2.5. Intensity set at 30 knots (10
minute).

The tropical low is under moderate shear, which is not forecast to ease, but
with SST above 29 degrees development is expected to continue. Given the small
size of 10U and the rapid organisation observed overnight, intensification
could be rapid.  

Environmental conditions become more favourable once the system reaches the
Gulf of Carpentaria with SSTs above 30C. From Wednesday the shear decreases and
upper divergence increases and rapid intensification becomes more likely.  

There continues to be significant variation between model runs regarding the
long term track, with some scenarios indicating the system recurves over the
Gulf waters and therefore maintains intensity.

TIGHTLY-CURVED BANDING WRAPPING INTO A SMALL MICROWAVE EYE FEATURE

IMPROVING CONDITIONS WITH NEAR-RADIAL OUTFLOW, LOW TO MODERATE (15
TO 20KTS) VERTICAL WIND SHEAR (VWS), AND WARM (29-30C) SEA SURFACE
TEMPERATURES (SST). BOTH ECMWF (08/12Z) AND GFS (08/18Z) ARE NOW
INDICATING A TROPICAL STORM STRENGTH SYSTEM MAKING LANDFALL NEAR TAU

REMARKS:
Tropical cyclone Tiffany continues to develop and has now reached category 2
intensity.

Position was analysed using animated enhanced infra-red and microwave satellite
imagery. Convection continues to develop and wrap around the centre with very
tight banding. Dvorak analysis is based on a curved band pattern with 0.8 to
0.85 wrap giving DT 3.5. MET is 2.5 based on a 24 hour D trend, and PAT is
adjusted up to 3.0. Final T 3.5, and CI is set to 3.5. This is supported by a
recent SMOS satellite pass indicating a small area of 50 knot winds near the
centre of the system. Intensity is set to 50 knots (10 minute mean).  

The CIMSS analysed deep layer wind shear has decreased slightly to 15 to 20
knots as the upper level ridge is deformed to the north by an upper trough
passing to the south. This same feature has improved upper poleward outflow
from the system. SST is above 29 degrees Celsius. Given the small size of
Tiffany, intensification could continue, however the circulation will start to
feel the effects of the coastline within the next 6 to 12 hours and thus the
current intensity is forecast to persist through to landfall.

Tiffany will continue to be steered westward by a mid-level ridge to the south
for the next several days. Late in the week another upper trough will weaken
the ridge. The system will slow and possibly recurve to the southeast. This is
likely to be after landfall on the Northern Territory coast, however
considerable uncertainty remains with this timing. Otherwise, conditions are
broadly favourable for development as the system tracks across the Gulf of
Carpentaria and the forecast development to a category 3 system in the western
Gulf remains credible.
