Position based on animated visible satellite imagery aided by recent OSCAT and ATMS polar orbiter passes. Dvorak analysis is based on a curved band pattern with a wrap of 0.6, giving DT 3.0. MET is 2.5 based on a 24 hour W+ trend, with PAT adjusted to 3.0. Final T 3.0, with CI held higher at 4.0. Recent objective aids at 0540 UTC (1 minute means) were ADT 63 kn, AiDT 48 kn, DPRINT 32 kn, and DMINT (0345 UTC) 36 kn, microwave sounders (0344 UTC) 61 kn, and SATCON 55 kn. Analysed intensity is 60 knots based on subjective Dvorak, above most objective aids to retain continuity with the 00 UTC analysis and earlier SAR intensity. The environment remains unfavourable for development, with CIMSS analysed deep layer wind shear easterly at about 20 to 25 knots. Some SST modelling suggests turbulent upwelling due to Maila's slow motion over several days has reduced local SSTs to around 24 to 26 degrees, which is also likely to be a contributing factor to weakening. All NWP guidance forecasts further weakening at varying rates as the easterly shear is generally maintained, and the system is likely to interact negatively with the Papua New Guinea land mass over the weekend. Maila has drifted very slowly SW over recent hours, with the steering pattern remaining nearly balanced. The bulk of NWP guidance suggests the western mid-level ridge will become more dominant over the next 24 hours and a WSW motion should become more firmly established. There remains some divergence in track guidance, however, with some scenarios weakening Maila in-situ over the Solomon Sea. The most likely track will take Maila southwest and close to southeastern Papua New Guinea, where a period of destructive winds is possible. After passing Papua New Guinea, Maila is expected to continue generally to the west to west-southwest towards the Cape York Peninsula. There remains considerable spread in the long term track and the forward speed of the system. Impacts to the Queensland coast are possible from as early as Monday through to mid next week, most likely about northern Cape York Peninsula. Recent guidance has backed more significant weakening as the system interacts with the land mass of Papua New Guinea, and Maila weakening below tropical cyclone intensity before reaching Cape York Peninsula is becoming an increasingly credible scenario.
