Geostationary\nsatellite images show a cold central convective area, with the\nlow-level center likely underneath the western portion of this\nconvection, although there have only been a couple of microwave\npasses over the past 6 to 12 hours, so confidence in the initial\nposition is still not particularly high.  Trudy also has loosely\nconnected outer curved convective bands to the northeast and west.\nThe latest subjective Dvorak estimate from TAFB is 3.5/55 kt, while\nobjective estimates from UW-CIMSS have been ranging from 36 to 45\nkt.  The intensity is increased to 50 kt for this advisory, since\nthe latest satellite images show continued gradual improvement in\nthe convective organization.\n \nTrudy has been moving toward the west-northwest, or 290/11 kt, to\nthe south of a mid-level ridge that extends over central Mexico.\nHowever, the ridge is expected to weaken by tomorrow, as Trudy moves\ncloser to Hurricane Simon.  The two tropical cyclones, which are\ncurrently about 700 n mi apart, are forecast to be within 500 miles\nof each other by hour 36, possibly close enough to influence each\nother's steering.  By Thursday, increasing mid- to upper-level\ntroughiness in the west-central Gulf of America and steering from\npotential interaction with Simon should cause Trudy to turn\nnorth-northwestward, and possibly northward for a time Thursday\nnight or Friday.  As Simon finally moves northwest and weakens late\nin the forecast period, it should allow the ridge to build back in\nand induce Trudy to make a leftward turn back toward the northwest.\nThere remains significant track spread among the models, but there\nhas been an overall rightward shift in the model guidance, mainly\nduring the first 60 to 72 h of the forecast, so the new NHC track\nforecast is well to the east of the previous one through 72 h. The\nNHC track forecast is slightly to the west of the HCCA and GDMI at\n36-72 h.  At day 5, the NHC forecast is slightly south of the\nprevious one, but well to the north of the latest GDMI, HCCA, and\nTVCN, but the forecast that far out is highly uncertain.\n \nEnvironmental conditions continue to look quite favorable along\nTrudy's track through the next 60 hours, and the NHC forecast\ncontinues to call for rapid intensification.  By hour 72, there is\nincreasing confidence that Trudy will reach stronger southwesterly\nwind shear, which should induce significant weakening by days 4 and\n5, regardless of how much land interaction Trudy incurs.  The NHC\nintensity forecast is at the high end of the model guidance\nthroughout the entire 5-day period, and is similar to the HCCA and\nGoogle DeepMind Ensemble Mean.\n \nNHC continues to call for Trudy to get close to the coast of Mexico\nas a major hurricane, and given the track uncertainty, residents of\nsouthwestern and west-central Mexico should continue to closely\nmonitor the progress of Trudy, and be ready to possibly implement\ntheir hurricane plan.\n \n \nKey Messages:\n \n1. Trudy is forecast to be a major hurricane as it approaches the\ncoast of southwestern and west-central Mexico late this week and\ninto the weekend. There is an increasing risk of wind, rain, and\nstorm surge impacts, and watches could be required for a portion of\nthese areas later today or tonight.\n \n \nFORECAST POSITIONS AND MAX WINDS\n \nINIT  14/1500Z 11.5N  99.5W   50 KT  60 MPH\n 12H  15/0000Z 12.1N 100.4W   60 KT  70 MPH\n 24H  15/1200Z 12.9N 101.2W   75 KT  85 MPH\n 36H  16/0000Z 13.7N 101.7W   90 KT 105 MPH\n 48H  16/1200Z 14.6N 102.0W  105 KT 120 MPH\n 60H  17/0000Z 15.5N 102.4W  115 KT 130 MPH\n 72H  17/1200Z 16.5N 103.0W  115 KT 130 MPH\n 96H  18/1200Z 18.4N 105.0W   95 KT 110 MPH\n120H  19/1200Z 19.9N 106.9W   75 KT  85 MPH\n \n"}
