REMARKS:
Ex-Tropical Cyclone Paul has weakened to be a tropical low. Ex-TC Paul was located using animated VIS imagery but with low confidence. Gales have been confined to within 30nm of the centre in only the southwest quadrant based on SMOS and SMAP information received around 19UTC. An ASCAT pass at 2240 UTC arrived after analysis was completed and confirms strongest winds are confined to the southwest quadrant and may already be below gale force intensity. The intensity of 35 knots is based on previous SMOS and SMAP information, and sits within the range of objective aids. Dvorak curved band analysis has become very challenging due to the rapid break down of the system, and a significant reduction of curvature, but on average over the last 3 hours a wrap of 0.3 gives a DT of 2.0. MET is 2.0 with a rapid weakening trend as deep convection becomes mostly confined to the southeast of the centre. No adjustment to MET. FT=2.0 with CI held higher at 2.5. Objective aids (1-minute): ADT 37kn; AiDT 34kn; DPRINT 30kn; SATCON 46kn. ADT RawT is 2.3 Ex-TC Paul remains in a region of high SSTs (29.5-30C) however environmental conditions are otherwise unfavourable for development. Wind shear at 0000 UTC was analysed as 21 kt from the NW (from CIMSS) and dry air is encroaching. Further weakening is expected on Friday before the system dissipates by Sunday. Ex-TC Paul has been slow moving with the influence of a mid-level ridge to the northeast and mid-level trough. The low level ridge to the west southwest is expected to become more dominant throughout Friday and a northwest track is expected.
