It is quite difficult to estimate where the low-level \ncenter is, and there have been no recent microwave images, \nscatterometer data, or nearby surface observations.  Based on the \nGOES proxy vis imagery, it is estimated that the center of Boris \nhas moved inland along the border of Oaxaca and Guerrero.  The \ninitial intensity has been brought down to 35 kt which could be \ngenerous, and is in good agreement with a blend of the latest \nsubjective and objective satellite intensity estimates.\n\nThe current motion is estimated to be north-northwest at 5 kt. A \nturn to the northwest is expected shortly as a mid-level ridge \nbuilds over the western Gulf of America, and little change has been \nmade to the NHC track forecast.  Model guidance is in good agreement \nshowing rapid weakening and dissipation occurring over land very \nsoon.  The NHC forecast indicates weakening to a remnant low by \nmidday today with dissipation by hour 24, although it is possible \nthat Boris could dissipate sooner.\n\nThe threat of heavy rainfall continues to be the primary hazard of \nconcern with this slow-moving system, which will likely result in \nflash flooding and mudslides in mountainous terrain through this \nmorning.\n \nKey Messages:\n \n1. Heavy rainfall associated with Tropical Storm Boris across \nportions of southern Mexico will subside by later today. Some risk \nof additional flooding and mudslides continues this morning, \nespecially in areas of steep terrain.\n \n2. Tropical storm conditions are likely occurring along the coast \nwithin the Tropical Storm Warning area and will continue through \nearly this morning.\n \n \nFORECAST POSITIONS AND MAX WINDS\n \nINIT  09/0900Z 16.4N  98.4W   35 KT  40 MPH\n 12H  09/1800Z 17.1N  99.1W   25 KT  30 MPH...POST-TROP/INLAND\n 24H  10/0600Z...DISSIPATED\n \n"}
