Tropical Cyclone Discussion
041 WTPA42 PHFO 262032 TCDCP2 Tropical Storm Lala Discussion Number 58 NWS Central Pacific Hurricane Center Honolulu HI CP012026 Issued by NWS National Hurricane Center Miami FL 1100 AM HST Wed Aug 26 2026 Satellite imagery reveals little change in Lala’s convective structure over the last couple of hours. Subjective Dvorak intensity estimates from HFO and JTWC at 1800 UTC were 35 and 30 kt, respectively, while objective estimates ranged from 45-50 kt. Given the relatively steady nature of Lala’s appearance on satellite imagery since the last advisory, the initial intensity was held at 40 kt. Lala’s speed remains slow, with an initial motion estimate of 320/4 kt. A high pressure ridge centered to the storm’s east-northeast will drive a slow storm motion toward the north-northwest, before the system gradually turns more westward as it moves away from the ridge’s influence. Little change was made to the track forecast from the last advisory package, as models generally exhibited good agreement in the track while Lala remains tropical. With the storm moving over gradually decreasing SSTs and increasing vertical wind shear, Lala is expected to become a post-tropical remnant low within the next 48 hours, right when the system is forecast to cross the international dateline. Changes to the intensity forecast were minimal, with the main adjustment being to show an earlier dissipation for Lala at 96 hours. This is sooner than the previous forecast, as global models generally depict the system becoming an open trough over the weekend.
