During the evening hours of February 10, 2009, a deadly, long-lived, and violent nocturnal tornado that was part of a small tornado outbreak tracked 37 miles (59 km) through portions of Jefferson County, Love County, and Carter County in Oklahoma, after initially touching down in Montague County, Texas, near Spanish Fort. The tornado devastated the city of Lone Grove, killing eight people, injuring another 46, and severely damaging and destroying numerous businesses, mobile homes, and single-family homes throughout the area. Six of the fatalities occurred in mobile homes, with the seventh being in a well-built home that was destroyed at EF4 intensity. The eighth fatality occurred when a truck driving on Interstate 35 was directly hit by the tornado, resulting in the driver's death. Around 114 homes were destroyed, with some mobile homes reported to have been completely obliterated. The tornado was the deadliest and most intense to strike Oklahoma during the month of February since reliable records began in 1950, and had the highest death toll of any tornado in the United States in 2009.
