Mitchell was located using Learmonth radar and there is high confidence in its position. Dvorak Analysis: DT=2.5 based on curved band with 0.4 wrap. MET is 2.5, with a W+ 24-hour trend and PAT agrees. FT 2.5. CI held at 3.5. Latest Objective guidance (1-minute mean) at 0000 UTC: ADT 51 kn, AiDT 45 kn, DPRINT 47 kn, DMINT 55 kn (2242 UTC). Intensity analysed as 45 knots. Deep convection decreased overnight but has been reinvigorated in the past few hours to the west of the system centre. Mitchell is in a marginal environment. Sea surface temperatures are around 26 C, dry air is wrapping around the equatorward side of the system and proximity to land are all likely to limit any re-intensification. CIMSS 00 UTC upper-level wind analysis estimates deep-layer vertical wind shear as north-northeasterly at 15.8 kn and is expected to remain favourable through Monday while poleward upper-level divergence remains strong, aided by a mid-level trough approaching from the southwest. Intensity is forecast to remain steady at 45 knots until Mitchell moves overland and weakens. Mitchell is moving south along the periphery of a mid-level ridge located to the east. During Monday, Mitchell will turn to the southeast and cross the coast due to the mid-level trough approaches from the southwest.
