A trailing, broken curved \nband remains displaced to the east of the center, likely the result \nof light-to-moderate south-southwesterly vertical wind shear and \nupper-level outflow displacement. The latest subjective Dvorak \nintensity estimates from both PHFO and PGTW were T3.0/45 kt, while \nobjective estimates from UW-CIMSS range from 31 to 43 kt. Given the \nlatest satellite presentation and the spread in available data, the \ninitial intensity is held at 40 kt for this advisory.\n\nThe initial motion is estimated to be westward, or 270/10 kt. Pena \nis forecast to maintain a generally westward motion over the next \nseveral days while being steered by a low- to mid-level ridge \nanchored north of the system across the central Pacific. As this \nridge shifts eastward, the cyclone is forecast to accelerate \nslightly while turning northwestward toward the end of the forecast \nperiod. The updated NHC track forecast closely mirrors the previous \ntrack and aligns with the latest HCCA aid.\n\nStatistical SHIPS guidance suggests that Pena will remain in \nenvironmental conditions favorable for strengthening, characterized \nby warm sea surface temperatures (SSTs), light vertical wind shear, \nand high mid-level moisture. However, given its current lack of \norganization, the cyclone may struggle to consolidate an inner core \nand take advantage of these conditions, raising uncertainty \nregarding its long-term survival. The dynamical and statistical \nguidance reflects this dilemma, showing a wide spread that ranges \nfrom intensification into a hurricane to complete dissipation before \nthe end of the forecast period. Consequently, forecast confidence \nremains lower than average. The updated NHC intensity forecast is \nlargely unchanged from the previous advisory, keeping the cyclone in \nthe middle of the multi-model envelope and below HCCA and GDMI \nconsensus aids.\n \n \nFORECAST POSITIONS AND MAX WINDS\n \nINIT  08/2100Z 11.6N 157.2W   40 KT  45 MPH\n 12H  09/0600Z 11.6N 158.6W   40 KT  45 MPH\n 24H  09/1800Z 11.5N 160.6W   40 KT  45 MPH\n 36H  10/0600Z 11.4N 162.6W   40 KT  45 MPH\n 48H  10/1800Z 11.4N 164.6W   45 KT  50 MPH\n 60H  11/0600Z 11.3N 166.8W   45 KT  50 MPH\n 72H  11/1800Z 11.3N 169.5W   50 KT  60 MPH\n 96H  12/1800Z 12.1N 175.8W   45 KT  50 MPH\n120H  13/1800Z 14.2N 178.4E   45 KT  50 MPH\n \n"}
