The latest Dvorak analysis was based on a curved band pattern with a 0.4 degree wrap, giving a DT of 2.5. MET and PAT were both 2.5. FT based on MET. This analysis was supported by ASCAT-B scatterometer data at 1157UTC, which indicated a broad area of 30 knot winds around the system. Confidence in the location of the system is considered good based on Willis Island radar imagery and surface observations from Lihou Reef. Pressure observations have declined significantly at Lihou Reef over the last 24 hours with an MSLP observation of 991.8hPa at 18UTC. The system is currently being steered to the south-southeast by the combination of a mid level ridge to the east, and an upper level trough moving eastwards across the Tasman Sea. During the weekend, this trough is expected to move further east, and a new mid level ridge should build to the south of the system, leading to a change to a westerly track, taking the cyclone onto the Queensland coast. All model guidance is in agreement with this scenario, although there are some differences in forward speed amongst the guidance, which affects not only the time of impact, but also the length of time available for the system to intensify over the water. The system is located in an area of weak vertical wind shear over SSTs of 29 to 30 degrees celsius. Upper level outflow is good in all quadrants, and may become further enhanced to the south due to the weak interaction with the upper trough. Overall, the environment will remain supportive of intensification right up to landfall on the Queensland coast. The intensity forecast is based on slightly more than a standard rate of intensification; given the favourable environment it is likely that there will be periods of more rapid intensification.
