502 WTPA42 PHFO 270844 TCDCP2 Tropical Storm Lala Discussion Number 60 NWS Central Pacific Hurricane Center Honolulu HI CP012026 Issued by NWS National Hurricane Center Miami FL 1100 PM HST Wed Aug 26 2026 Mid-level dry air is beginning to wrap around the core of Lala, although a small area of deep convection persists near the center. An earlier AMSR-2 microwave pass indicated that moderate westerly wind shear is starting to take its toll, with a more defined circulation to the north and east of the center, and less definition on the southern and western sides. Subjective Dvorak intensity estimates from PHFO and JTWC were 2.0/30 kt, while objective intensity estimates from UW-CIMSS range from 47-55 kt. The initial intensity is maintained at 40 kt for this advisory. Lala is moving northward around 5 kt, steered by a ridge of high pressure centered to the northeast of the storm. A northward to northwestward motion is expected over the next 24 h, followed by a turn toward the west-northwest as Lala approaches and crosses the International Date Line. Increasing wind shear and drier mid-level air will support gradual weakening over the next couple of days, and Lala may struggle to sustain deep, organized convection by late Thursday night or early Friday morning. The latest NHC track forecast has been shifted slightly to the right of the previous forecast and calls for Lala to become a post-tropical low by 36 h. The remnants of Lala should then gradually spin down and degenerate into a trough within about 3 days.
