Tropical Storm Erin was a minimal tropical storm that made landfall in Texas in August 2007. The storm's remnants also unexpectedly restrengthened over Oklahoma, causing damage there as well. The second tropical cyclone to make landfall in the United States in the 2007 Atlantic hurricane season and the fifth named storm of the year, Erin 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, 2007 Erin made landfall near Lamar, Texas, and persisted over land across Texas before moving northward into Oklahoma. Due to the brown ocean effect, Erin intensified after landfall. The storm resulted in 16 fatalities and worsened an already-severe flooding issue in Texas.
