Three tornado sirens in the Nebraska Panhandle have failed their tests. A siren in Harrisburg, one in Morrill and one Terrytown didn't go off during Wednesday's checks. Jerry Bretthauer of the Region 22 Emergency Management Agency, says signal issues could have caused the problems. In Lincoln and Lancaster County, everything went off without any problems. Lancaster County Emergency Management coordinator Doug Ahlberg tells KFOR News always remember sirens will sound if a spotter has seen a funnel cloud or tornado on the ground and as a last resort, if spotters have not yet been deployed. They are for outdoor warning only. Ahlberg adds that everyone involved in the warning process, including area hospitals, rehearsed their plans and had no problems with the protocol.
