That day , an eye rapidly formed within the system and it became a tropical storm just 60 mi ( 95 km ) southeast of Galveston , Texas . Soon thereafter , a weather reconnaissance plane reported a barometric pressure of 1000 mbar ( hPa ; 29 @.@ 53 inHg ) at the storm 's center . Around 18 : 00 UTC ( 1 : 00 p.m. CDT ) , the newly named Abby attained peak winds of 65 mph ( 100 km / h ) . It subsequently made landfall near Matagorda , Texas four hours later . Once onshore gradual weakening ensued , though a brief period of re @-@ organization delayed its dissipation . Abby degenerated into an area of showers on August 8 southwest of San Antonio , Texas .
