000 WTPA42 PHFO 192035 TCDCP2 Hurricane Lala Discussion Number 30 NWS Central Pacific Hurricane Center Honolulu HI CP012026 Issued by NWS National Hurricane Center Miami FL 1100 AM HST Wed Aug 19 2026 Lala has weakened slightly as the eye of the hurricane does not appear to be as pronounced as before, and the cloud tops of the deep convection in the eyewall have warmed slightly as well. The most recent subjective Dvorak intensity estimates from HFO and JTWC for Lala were both T5.5/102 kt. The objective intensity estimates from UW-CIMSS range from 99-113 kt. From a blend of this data and the latest satellite trends, the initial intensity has been lowered to 105 kt for this advisory. The cyclone has been moving toward the north-northwest at 315/8 kt. However, a more gradual turn to the north should be occuring soon as a ridge that was previously to the north of the hurricane begins to weaken due to the approach of a mid- to upper-level trough from the northern Pacific. The current NHC forecast track does not have many changes from the previous one until around 36 h, where the updated forecast lies slightly to the west of the previous one. Once the system turns to the northwest again, the new track and the old track become very similar again. The other change to the forecast was that the speed of Lala was increased slightly. The current model and satellite trends are indicating that Lala will continue to weaken as it moves farther north and west away from the main Hawaiian Islands. The current NHC intensity forecast continues to maintain the system as a strong and powerful hurricane as it tracks toward and past the Papahanaumokuakea Marine National Monument. The wind shear should start to increase more as the cyclone moves farther north as the favorable trough interaction decreases. In addition, past 60 h, the hurricane is expected to enter a drier environment, that should keep the weakening trend going. Given these factors, the current NHC intensity forecast shows a steady weakening trend throughout the forecast period and lies near the simple and corrected intensity consensus.
