000 WTPA42 PHFO 230844 TCDCP2 Tropical Storm Lala Discussion Number 44 NWS Central Pacific Hurricane Center Honolulu HI CP012026 Issued by NWS National Hurricane Center Miami FL 1100 PM HST Sat Aug 22 2026 Visible satellite images before sunset showed the well-defined center of Lala surrounded by pronounced curved convective bands. Infrared cloud top temperatures closer to the center have warmed within the decaying eyewall. A blend of the latest HFO and JTWC Dvorak intensity estimates and the earlier scatterometer data support holding the initial intensity at 60 kt for this advisory. The storm is moving slowly to the northwest (325/6 kt) with a mid-level ridge positioned to its north and northeast. This ridge is forecast to slide eastward and build over the northern Pacific during the next several days. This should keep Lala on a slow northwestward track through the forecast period. While the track models agree on this general scenario, there is notable cross-track spread in the extended range with the Google Deep Mind and GFS solutions on opposite sides of the guidance envelope. The updated NHC track forecast is slightly slower than the previous one, with small westward adjustments beyond 48 h that trend closer to the latest corrected multi-model consensus (HCCA). Lala is centered over waters slightly warmer than 26C in a relatively weak shear environment. With no baroclinic features forecast to impart shear on the storm or induce its extratropical transition, Lala is predicted to only gradually weaken during the next couple of days. After 48 h, the storm will move over progressively cooler waters, and the updated NHC prediction shows steady weakening during the latter half of the forecast. GFS and ECMWF simulated satellite images suggest Lala could struggle to sustain organized convection by midweek, and this forecast shows the system becoming a post-tropical remnant low by 120 h.
