000 WTPZ42 KNHC 311439 TCDEP2 Hurricane Frank Discussion Number 22 NWS National Hurricane Center Miami FL EP072022 800 AM PDT Sun Jul 31 2022 An 0933 UTC AMSR2 microwave overpass revealed the fragments of a small inner eye and a much larger 60 to 75 n-mi-wide eye. Since that time, the cloud tops have generally warmed with a small CDO feature remaining. Frank's outflow is still well established owing to the low vertical wind shear conditions. Objective and subjective Dvorak intensity estimates range between 65 and 77 kt, so the initial intensity has been lowered to 75 kt for this advisory. Frank has crossed the 26 degree Celsius isotherm and will be moving over progressively cooler waters during the next few days. In addition, the storm will be entering a drier and more stable environment. Thus, steady weakening is expected, and Frank is forecast to become a post-tropical cyclone within 72 hours, and dissipate by the end of the period. The NHC intensity forecast follows the HCCA and IVCN consensus aids closely and is essentially an update of the previous advisory. Frank is moving northwestward or 315/10 kt. The cyclone should move on a general northwestward track over the next couple of days around the southwestern portion of a mid-level ridge. After that time, a weaker and more shallow system is predicted to decelerate and turn north-northwest to northward within the low-level flow. The updated NHC track forecast is in good agreement with the latest consensus models and is very close to the previous official forecast.
