LOVELADY (MCT) — Surveys by National Weather Service teams have determined that damaging windstorms that swept parts of East Texas on Sunday were weak tornadoes.

One of the tornadoes, which a survey team classified as of EF-1 strength, destroyed three mobile homes in the small East Texas town of Lovelady. The Enhanced Fujita Scale describes an EF-1 as one of 73-113 mph capable of severely damaging outbuildings, tearing the roof from a weak wood-frame house and causing minor damage to a strongly built wood-frame house.
