Issued at 200 PM PDT Sun Jul 09 2017 000 WTPZ45 KNHC 092031 TCDEP5 Hurricane Eugene Discussion Number 9 NWS National Hurricane Center Miami FL EP052017 200 PM PDT Sun Jul 09 2017 Eugene continues to have a distinct eye surrounded by a ring of very deep convection. A blend of both objective and subjective Dvorak T-numbers from all agencies yield an initial intensity of 100 kt. The hurricane has the opportunity to strengthen a little more within the next 12 hours or so, before the circulation of Eugene begins to move over cooler waters of 24 degrees Celsius or lower. After that time, weakening should begin, and the cyclone should become post-tropical in about 3 days. This forecast follows both statistical models and the consensus. Eugene is moving toward the northwest or 325 degrees at 10 kt. The cyclone is embedded within a well established steering flow around a mid-level ridge over the western United States, and this pattern will keep Eugene on the same general track for the next 3 days. Once the cyclone weakens, it could turn more to the west-northwest with the low-level flow. The NHC forecast follows the consensus primarily during the next 3 days and does not depart much from the previous official forecast.
