The analysis position is assessed with low confidence based on recent visible imagery. Over the past six hours the system structure has deteriorated significantly. Deep convection over the system centre has ceased, and the exposed low-level circulation has become elongated and poorly defined. Intensity is set at 30 kn. An partial ASCAT pass at 0235 UTC indicated that gales were no longer present in the SW quadrant. Dvorak analysis: No DT could be assigned due poor cloud structure; MET=2.0 based on a 24 h W+ trend, PAT has been adjusted down to 1.5; FT/CI = 1.5/2.0, with FT based on the PAT. The remnants of Bakung have been moving slowly towards the north under the influence of a ridge in the lower levels. The system is expected to move to the north east and out of the Australian region close to 10S Thursday. The system is not expected to redevelop.
