518 WTPZ42 KNHC 070231 TCDEP2 Hurricane John Discussion Number 6 NWS National Hurricane Center Miami FL EP122018 900 PM MDT Mon Aug 06 2018 John's satellite presentation has not changed significantly during the past few hours. The tops warmed up significantly earlier, but a new convective curved band is developing around the eye as we speak. T-numbers from TAFB and SAB are 4.0 on the Dvorak scale and on this basis, the initial intensity is keep at 65 kt in this advisory. The environment is quite favorable for intensification, and although the intensity guidance is not as aggressive as earlier, it still shows a strengthening hurricane, and this is reflected in the NHC forecast. Beyond 3 days, John should be moving over cooler waters, and rapid weakening should then begin. John is very likely to become a remnant low by day 5 or perhaps earlier. John continues to move toward the northwest or 315 degrees at 7 kt, steered by the flow around a strong subtropical ridge extending from the western United States westward across the Pacific. Since the steering pattern is well established, track models are tightly clustered increasing the confidence in the forecast. NHC keeps the hurricane in the middle of the guidance envelope very close to the HCCA corrected consensus and is not very different from the previous one. The core of John with its strongest winds is forecast to remain well off the Baja California Peninsula, but having said that, any deviation to the right of the track or an unexpected increase in the area of tropical force winds, could bring tropical-storm-force winds to portions of the west coast of the peninsula. Therefore, interests in the southern portion of the Baja California Peninsula should monitor the progress of this hurricane.
