Post-Tropical Cyclone OLIVIA Forecast Discussion
769 WTPA45 PHFO 140242 TCDCP5 Post-Tropical Cyclone Olivia Discussion Number 54 NWS Central Pacific Hurricane Center Honolulu HI EP172018 500 PM HST Thu Sep 13 2018 An earlier flare up of deep convection within the northeast and east flanks of Olivia caused the low-level center to slow down, then accelerate off to the west as nearby thunderstorms collapsed. Strong westerly vertical wind shear of around 35 kt has now displaced the diminishing convection nearly 90 n mi to the east of the elongated and fully exposed low-level center. HFO came up with a subjective Dvorak current intensity estimate of 1.5, while JTWC and SAB are no longer classifying the system. Given the lack of organized deep convection, Olivia is deemed a post-tropical low with an intensity of 30 kt, and this will be the last advisory. The initial motion is set at west (260 degrees) at 13 kt. The weak low-level center was earlier drawn toward a pulsing area of convection, then recently emerged farther north than expected, leading to some uncertainty in the initial motion. A low-level ridge to the north will steer the remnant low of Olivia westward through tomorrow. Increased interaction with a developing upper-level low sitting just north of the remnant surface low will cause a turn toward the west-northwest Friday night and Saturday. The upper-level low will maintain strong vertical wind shear that should lead to dissipation of the remnant surface low during the weekend. The intensity forecast is in line with the SHIPS and LGEM guidance.
