985 WTPA42 PHFO 251444 TCDCP2 Tropical Storm Lala Discussion Number 53 NWS Central Pacific Hurricane Center Honolulu HI CP012026 Issued by NWS National Hurricane Center Miami FL 500 AM HST Tue Aug 25 2026 The satellite presentation of Lala remains about the same as it has been for the last couple of days. The cyclone continues to have well-defined curved bands of shallow-to-moderate convection with coldest cloud tops of -60 to -65 deg C. Upper-level outflow is strongest over the northern semicircle of the circulation. Based on an earlier scatterometer overpass with little change in structure since that pass, the advisory intensity remains at 45 kt. Latest center fixes show that the storm is moving slowly west-northwestward with a motion estimate of around 300/5 kt. The primary steering feature at this time is a weak mid-tropospheric ridge to the northeast of Lala. The global models indicate that the stronger higher-latitude southwesterly flow will continue to be well-removed from the cyclone for the next few days. Therefore the system is likely to continue a slow forward motion for the next 72 hours or so. The official track forecast is similar or very slightly to the west of the one from the previous advisory. This is close to the latest corrected consensus, HCCA, solution. Lala is forecast to traverse SSTs of about 23-24 deg C through Thursday and remain within a relatively dry low- to mid-level air mass. These conditions should lead to slow weakening and gradually diminishing deep convection. It is likely that the system`s deep convection will have decreased to the point that Lala will become a post-tropical cyclone by around 60 hours, and this is reflected in the latest NHC forecast.
