CISCO, Texas (AP) One person has been killed after a tornado struck a rural farming and ranch area about 100 miles west of Fort Worth.

Cisco Fire Chief Walter Fairbanks reports the one fatality as authorities are searching homes in Eastland County that were damaged by the twister that hit late Saturday afternoon.

The Eastland County judge, Rex Fields, says some people were unaccounted for but torrential rains were making the initial canvasses difficult.

He says there is "a considerable amount of damage" but the tornado did not strike any heavily populated area.

A 50-county area of North Texas was under a tornado watch until 9 p.m.
