The fifth named storm of the season, it formed in the Gulf of Mexico on August 14 from a persistent area of convection. It attained tropical storm status the next day, and on August 16 Erin made landfall near Lamar, Texas, and persisted over land across Texas before moving northward into Oklahoma. The storm resulted in at least 16 fatalities and worsened an already-severe flooding issue in Texas.
