REMARKS:
Severe Tropical Cyclone Maila continues to intensify in the Solomon Sea. Position is based on EIR imagery and lightning detection with fair confidence. There have been no recent microwave passes. A recent ASCAT pass at 1121 UTC sampled part of the western side of the circulation and showed gales extending to 110 nm in the northwest quadrant and 80 nm in the southwest quadrant. Recent satellite imagery shows a large central dense overcast over the low-level centre, with frequent lightning near the core. Intensity is assessed at 65 knots, biased above the subjective Dvorak estimate on the strength of the DPRINT objective guidance. Dvorak analysis gives an embedded centre pattern with DT=5.0, based on an embedded distance greater than 50 nm. MET=3.5 with a developing trend, and PAT 4.0. FT and CI are based on PAT rather than the embedded centre pattern. Available objective guidance at 1120 UTC (all 1-minute mean) includes ADT 61 kn, AiDT 65 kn and DPRINT 87 kn. DMINT, MW sounders and SATCON were unavailable. Maila has continued to consolidate and the environment remains favourable for further intensification. Vertical wind shear has decreased to below 15 knots, SSTs are near 30C, moisture remains ample, and upper-level outflow is good. Guidance supports further intensification through Tuesday, followed by possible weakening thereafter. The extent of any later weakening will depend on the motion of the system and whether it tracks closer to land. The steering pattern remains finely balanced, with a ridge to the south and northwesterly flow to the north, resulting in slow and at times erratic motion through about Wednesday. From mid-week, steering is expected to become more complex. A mid-level ridge strengthening to the east is the most likely influence to take Maila west or southwest into the Coral Sea. However, ensemble guidance shows considerable spread later in the week, with some members taking the system south into the Coral Sea and others westwards towards the far north Queensland coast. Confidence in the longer-term track remains low.
