Position was located using satellite imagery, aided with a recent AMSR2 Microwave pass at 1448 UTC. Deeper convection has remained on the western side of the LLCC, with curvature starting to show signs of improving. Dvorak analysis yields a DT = 1.5 from 0.3 wrap. MET = 1.5 with PT adjustment to 2.0. FT/CI = 2.0. Intensity is set at 30 knots. There are no objective aids available. ASCAT at 1054 UTC showed an elongated centre with 30 knot winds on the northern and western sides. While gales may develop in the northern quadrants in the next 6 hours, these gales are not expected to wrap more than halfway around the centre until 1800 UTC 4 April (24 hours). 37U is under high shear of around 20 knots, which is expected to lower as an upper trough to the southeast moves away. 37U is slow moving and is looping around the Solomon Sea. Next week a mid-level ridge to the east will strengthen, and is expected to direct 37U towards the southwest, but confidence in the longer term steering is low.
