Position is based on animated visible imagery with good confidence. Recent imagery has shown an eye reemerging. SSMIS microwave imagery at 1850 UTC captured the eastern side of the eye. Earlier SAR at 1906 UTC and recent ASCAT at 2237 UTC have given good guidance of the gale and storm force wind structure. Intensity is assessed at 80 kn, and is in line with Dvorak and generally in line with recent objective aids as well as the earlier SAR pass. Dvorak analysis, a OW eye with LG surrounds and eye adjustment yields a 3 hour average DT of 5.0. MET=5.5 based on a D 24h trend with an adjustment to 5.0. FT/CI=5.0/5.0. Available objective guidance at 0000 UTC (all 1-minute mean) includes ADT 63 kn, AiDT 65 kn, DPRINT 94 kn, DMINT 88kn (1803 UTC), and SATCON 85 kn (1730). Maila lies in a generally favourable environment with low to moderate vertical wind shear (about 15 knots), a moist environment and good upper-level divergence. However the intensity forecast for Maila is difficult with some guidance indicating an intense system persisting for some days and other guidance suggesting weakening. The slow motion may cause upwelling of cooler waters and the forecast slow motion of the system over these cooler waters may induce some weakening. As Maila moves further west there is the potential for some reintensification prior to tracking west southwest over southeastern PNG. The short term forecast maintains a similar intensity, however, some fluctuations are anticipated. The longer term intensity as it approaches the Queensland coast may depend on the systems interaction with PNG, as well as how quickly Maila moves west which leads to some variations in guidance in potential for Maila to be influenced by some vertical wind shear. The steering pattern is in balance, though northwesterly flow to the north is currently having the greatest influence and Maila has been moving slowly eastwards. This is expected to shift during today as a new mid-level ridge builds to the southwest. Maila is expected to slow while the pattern changes, and then the ridge becomes the dominant steering influence moving Maila to the northwest from later today. In the coming days the mid-level ridge is forecast to extend eastwards, to the south and southeast of Maila, and by Thursday is expected to steer Maila west southwest. This takes Maila past southeastern PNG, and they could face a prolonged period of very hazardous winds. After passing PNG, Maila is expected to continue moving generally west, and towards the Cape York Peninsula, however, there is considerable spread in the speed of motion and an impact could occur as early as Friday night or be delayed until early next week.
