Hurricane Norman Forecast Discussion Number 23

2018-09-02 22:34:19| National Hurricane Center (East Pacific)

Issued at 200 PM PDT Sun Sep 02 2018 670 WTPZ41 KNHC 022034 TCDEP1 Hurricane Norman Discussion Number 23 NWS National Hurricane Center Miami FL EP162018 200 PM PDT Sun Sep 02 2018 Norman has maintained a very distinct eye with a ring of deep convection all day. T-numbers from both TAFB and SAB have not changed and still are T6.0 on the Dvorak scale. On this basis, the initial intensity is being kept at 115 kt in this advisory. The hurricane, however, will begin to approach lower SSTs, and intensity guidance is responding to the cooler water by gradually weakening the hurricane. The NHC forecast continues to follow the intensity consensus IVCN, and forecasts a gradual weakening beyond 12 hours. Norman is moving toward the west-northwest at 16 kt. There is a strong subtropical ridge anchored to the north of the hurricane, and this flow pattern will continue to steer the cyclone between the west and west-northwest at the same speed for the next 2 days or so. After that time, Norman will be near the southwestern edge of the ridge, and a turn toward the northwest should then begin. Most of the guidance shifted northward at very long ranges, so the NHC forecast was slightly adjusted in that direction accordingly.
