SUMMARY OF 500 PM HST...0300 UTC...INFORMATION ---------------------------------------------- LOCATION...12.0N 158.5W ABOUT 645 MI...1035 KM S OF HONOLULU HAWAII ABOUT 520 MI...835 KM SSW OF SOUTH POINT HAWAII MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...W OR 265 DEGREES AT 17 MPH...28 KM/H MINIMUM CENTRAL PRESSURE...1007 MB...29.74 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 PM HST (0300 UTC), the center of Post-Tropical Cyclone Greg was located near latitude 12.0 North, longitude 158.5 West. The post-tropical cyclone is moving toward the west near 17 mph (28 km/h), and this general motion is expected to continue into Friday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Greg is forecast to dissipate on Friday. The estimated minimum central pressure is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- None NEXT ADVISORY ------------- This is the last public advisory issued by the Central Pacific Hurricane Center on this system. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service in Honolulu, under AWIPS header HFOHSFNP, WMO header FZPN40 PHFO, and online at weather.gov/hfo/HSFNP. $$ Forecaster Birchard

Post-Tropical Cyclone GREG Forecast Discussion
000 WTPA43 PHFO 180240 TCDCP3 Post-Tropical Cyclone Greg Discussion Number 17 NWS Central Pacific Hurricane Center Honolulu HI EP082023 500 PM HST Thu Aug 17 2023 A burst of convection that developed in Greg's northern semicircle this morning was unable to wrap around the cyclone's core, apparently due to moderate vertical wind shear. A 2058Z ASCAT pass found a couple 35 kt wind barbs in association with this convection, while also indicating that a closed low-level circulation center (LLCC) may no longer exist. Since then, disorganized convection has once again developed north of the center, while visible satellite imagery shows a fully exposed and elongated LLCC. Given the cyclone's inability to sustain deep convection over the increasingly ill-defined center for a prolonged period of time, Greg is deemed to be post-tropical with this advisory. Maximum sustained winds in the northern semicircle are estimated to be near 30 kt. The initial motion vector is a somewhat uncertain 265/15 kt, as the elongated LLCC appeared to relocate westward in response to this morning's convection. The remnant low will move generally toward the west (or just south of west) within the trade wind flow supplied by a surface high far to the north as it weakens to a trough on Friday. The updated track and intensity forecasts are strongly guided by regional and global dynamical model guidance. This is the last advisory issued by the Central Pacific Hurricane Center on this system. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service in Honolulu, under AWIPS header HFOHSFNP, WMO header FZPN40 PHFO, and online at weather.gov/hfo/HSFNP.
