Although recent \nscatterometer passes missed the circulation, microwave imagery shows \nan improving structure, with convective banding now evident over the \nsouthern and eastern quadrants. Subjective and objective satellite \nintensity estimates from TAFB and UW-CIMSS range from 47 to 55 kt. \nGiven the improved satellite presentation, the initial intensity is \nraised to 55 kt for this advisory, leaning toward the higher end of \nthese estimates.\n\nThe system is moving north-northwestward, or 340/6 kt. A decrease in \nforward speed is expected today as the cyclone turns northward, \nnortheastward, and then east-northeastward tonight in response to a \ndeepening trough moving into the eastern Pacific toward the western \ncoast of the United States. An east-northeastward to eastward motion \nis forecast for the rest of the week as Odalys is steered within the \nflow of the trough. Toward the end of the forecast period, the track \nforecast becomes increasingly uncertain due to a potential binary \ninteraction with Hurricane Polo as it tracks toward Baja California, \nwhich could cause Odalys to slow down late in the period. The latest \nNHC track forecast is similar to the previous advisory, though \nnudged slightly leftward and slowed down given the model uncertainty \naround day 5.\n \nEnvironmental conditions are becoming more conducive for \nstrengthening over the next couple of days, as vertical wind shear \nslightly decreases, with abundant mid-level moisture, and warm sea \nsurface temperatures. Thus, Odalys is forecast to become a hurricane \nlater today or tonight. In 48 to 72 hours, the cyclone is expected \nto encounter a drier mid-level air mass and may experience increased \nwind shear induced by upper-level outflow from Hurricane Polo. The \nlatest NHC intensity forecast remains near the upper end of the \nguidance, aligned closely with the HCCA and GDMI aids.\n \n \nFORECAST POSITIONS AND MAX WINDS\n \nINIT  22/0900Z 14.7N 130.4W   55 KT  65 MPH\n 12H  22/1800Z 15.1N 130.2W   65 KT  75 MPH\n 24H  23/0600Z 15.3N 129.3W   75 KT  85 MPH\n 36H  23/1800Z 15.4N 128.0W   75 KT  85 MPH\n 48H  24/0600Z 15.8N 126.6W   75 KT  85 MPH\n 60H  24/1800Z 16.3N 125.3W   70 KT  80 MPH\n 72H  25/0600Z 17.0N 124.4W   65 KT  75 MPH\n 96H  26/0600Z 18.5N 123.2W   60 KT  70 MPH\n120H  27/0600Z 20.2N 122.5W   50 KT  60 MPH\n \n"}
