Local Weather History For July 27th...
1980: A small tornado struck an onion packing warehouse in Dimmitt around 12:30 AM knocking it from its foundation and
carrying some pieces as far as 600 yards. Two watchmen were present during the tornado and one was able to get into a
small room avoiding injury. The other man suffered facial cuts and a broken nose as he jumped into a pickup. He was
narrowly missed as a piece of 2x4 was driven through the top of the vehicle into the floor of the cab. A piece of
four-inch pipe was found embedded 2.5 feet in concrete pavement. The tornado continued northeast damaging mostly wheat
fields. Total damages were estimated near $500,000.
