Tropical Storm Erin was the second tropical cyclone to make landfall on the United States in the 2007 Atlantic hurricane season. It was also the fifth named storm of the season. Erin formed in the Gulf of Mexico on August 14 from an area of convection which was becoming stronger. It became stronger and changed into a tropical storm the next day, and on August 16 Erin made landfall near Lamar, Texas and was able to not die as it moved over land across Texas before moving towards the north into Oklahoma. The storm killed at least 17 people and made an already-severe flooding problem in Texas even worse. Another different storm that Erin went into killed at least 18 people.
