SUMMARY OF 500 AM HST...1500 UTC...INFORMATION ---------------------------------------------- LOCATION...11.2N 149.7W ABOUT 690 MI...1105 KM SSE OF HILO HAWAII ABOUT 885 MI...1420 KM SE OF HONOLULU HAWAII MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...W OR 270 DEGREES AT 16 MPH...26 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 AM HST (1500 UTC), the center of Post-Tropical Cyclone Akoni was located near latitude 11.2 North, longitude 149.7 West. The post-tropical cyclone is moving toward the west near 16 mph (26 km/h), and this motion is expected to continue the next couple of days, with some increase in forward speed over the weekend. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Little change in strength is forecast during the next couple of days. 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, unless regeneration occurs. For additional information on the remnant low, please see High Seas Forecasts issued by the National Weather Service, under AWIPS header HFOHSFNP, WMO header FZPN40 PHFO, and available on the Web at weather.gov/hfo/HSFNP. $$ Forecaster Birchard

Post-Tropical Cyclone AKONI Forecast Discussion
000 WTPA43 PHFO 061444 TCDCP3 Post-Tropical Cyclone Akoni Discussion Number 10 NWS Central Pacific Hurricane Center Honolulu HI EP122019 500 AM HST Fri Sep 06 2019 Although showers and thunderstorms continue to pulse near Akoni's elongated low-level circulation center (LLCC), they have not been sufficiently persistent or organized to continue to classify the system as a tropical cyclone, and Akoni is being downgraded to a post-tropical remnant low. An overnight ASCAT-C pass showed southerly winds to 30 kt in an area east of the center, and that will be the initial intensity for this advisory. The initial motion estimate is a very uncertain 270/14 kt, as it appears that the LLCC has re-formed west of its previous location. A low- to mid-level ridge will strengthen far north of the remnant low over the next couple of days, and the associated gradient will likely support 30 kt winds in the northern semicircle. The high will also drive the system toward the west to west-northwest, with an increase in forward speed expected over the weekend. Little change in strength is expected until the system encounters increased vertical wind shear toward the latter part of the forecast period. This is expected to cause the low to weaken and open into a trough by day 4 or 5, similar to the solutions presented by GFS and ECMWF guidance. This is the last advisory issued by the Central Pacific Hurricane Center on this system, unless regeneration occurs. For additional information on the remnant low, please see High Seas Forecasts issued by the National Weather Service Honolulu, under AWIPS header HFOHSFNP, WMO header FZPN40 PHFO, and available on the Web at weather.gov/hfo/HSFNP.
