The impacts were primarily felt in Hidalgo and Cameron County, which were still recovering from ample rainfall and remnant flooding from Hurricane Hanna at the end of July. Standing water from Hurricane Hanna was still reported across western Cameron, southeast Hidalgo, and southwest Willacy with road closures still in place at the beginning of August.
