By 6:29PM, the tornado had expanded to just over 600 yards wide and was approaching maximum intensity. It continued to move northeast exiting the Wichita metro area and reached F5 intensity as it tore through the town of Andover, Kansas. The warning siren had failed, but most people had heeded warnings by local news media and police. Around 6:40PM, the tornado made a direct hit on the Golden Spur Mobile Home Park. Thirteen people were killed as the trailer park was obliterated, with little left there but scattered debris and twisted mobile home frames. The death toll included a father and son who abandoned their car and sought shelter in a ditch nearby. Extensive wind-rowing of debris and grass scouring was noted as the tornado swept large, well-constructed homes with anchor bolts cleanly from their foundations just west of N Andover Road as the tornado passed through densely populated residential areas. Vehicles were thrown nearly a mile from where they originated, and trees in the area were completely debarked. One vehicle that originated at the Golden Spur mobile home park was thrown 3/4 of a mile, and was so thoroughly mangled that surveyors could not determine if it was a car or a truck. The tornado then veered north, missing a Girl Scout camp where summer camp training was being conducted and a troop campout. The tornado then moved on to the northeast, passing just south of Towanda. The damage in this area was rated at F4 intensity as additional well-built homes were leveled. The tornado continued northeast and reached El Dorado Lake just before 7pm (CST). Video taken by local storm chasers shows that the tornado crossed over the lake and revealed a multiple vortex structure. Just after crossing over the lake to the northeast, the circulation dissipated and died out. The Andover tornado had traveled for nearly 46 miles, and was on the ground for over an hour. During that time, not only were 13 people killed, but the tornado had also left a third of Andover's 4,300 residents homeless, and destroyed 300 homes, 10 businesses and two churches.
