Gradual strengthening is expected during the next few days, and Lowell could become a hurricane by Monday or Monday night. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- None NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system. Future information on this system can be found in Public Advisories issued by the Central Pacific Hurricane Center beginning at 500 AM HST, under AWIPS header HFOTCPCP4, WMO header WTPA34 PHFO.

TROPICAL STORM LOWELL DISCUSSION
Expires:No;;598203 WTPZ42 KNHC 300836 TCDEP2 Tropical Storm Lowell Discussion Number 11 NWS National Hurricane Center Miami FL EP122026 1100 PM HST Sat Aug 29 2026 Lowell remains a sheared tropical cyclone this evening. Moderate easterly vertical wind shear continues to displace the bulk of the deep convection over and west of the low-level circulation center. With little change in the satellite presentation, a blend of a scatterometer pass this evening, the latest objective intensity estimates, and the subjective Dvorak intensity estimate from TAFB supports holding the initial intensity at 45 kt for this advisory. Lowell is moving westward, or 270/9 kt. A low- to mid-level ridge positioned north of the cyclone should remain the primary steering influence during the next couple of days, resulting in a continued generally westward motion. The track guidance remains in relatively good agreement during this period. Thereafter, considerable cross-track spread persists, likely due in part to the potential influence of Hurricane Karina to the northeast on Lowell’s steering flow. The latest HCCA and Google DeepMind ensemble mean have changed little over the past several cycles and remain near the southern edge of the guidance envelope, while the GFS, regional hurricane models, and simple consensus (TVCN) continue to favor a gradual west-northwestward to northwestward turn later in the forecast period. Given the considerable spread among these solutions, the latest NHC track forecast continues to reflect a blend of the previous forecast, HCCA, and Google DeepMind ensemble mean. Moderate easterly vertical wind shear continues to affect Lowell and should temper the rate of strengthening in the short term. The shear is forecast to decrease during the next day or so, which should allow the cyclone to become better organized. Gradual strengthening is forecast through about 36 h, followed by a faster rate of intensification through 72 h as environmental conditions become more favorable. Although some mid-level dry air could limit the rate of intensification, all of the intensity guidance supports continued strengthening, with Lowell forecast to become a hurricane in about 48 h, with some additional strengthening thereafter. The intensity forecast becomes increasingly uncertain later in the period due to Lowell’s potential interaction with Karina. A slower and more northwestward track, as shown by the GFS and some of the regional hurricane models, would bring Lowell closer to Karina and could expose the cyclone to stronger vertical wind shear associated with Karina’s outflow, resulting in a weaker cyclone. Conversely, a farther-south track would likely keep the two cyclones sufficiently separated and allow Lowell to maintain its strength or continue strengthening. The latest NHC intensity forecast remains near the middle of the guidance envelope and is close to the consensus (IVCN). Lowell is forecast to reach the central Pacific basin in the next few hours, and the next advisory will be issued by the Central Pacific Hurricane Center at 1500 UTC/500 AM HST. Users will not need to change where they obtain information on Lowell, which will continue to be available on the web at hurricanes.gov.
