(AP) A Dallas-Fort Worth television station owned and operated by NBC is apologizing for not airing warnings promptly as a tornado raked Dallas.

While other network-affiliated stations went wall-to-wall with weather coverage about the tornadoes Sunday night, including one that devastated parts of northern Dallas, KXAS stayed with the football game between the Dallas Cowboys and the Philadelphia Eagles.

KXAS apologized in a statement issued Monday, saying it “made a mistake by not immediately interrupting the football game with a tornado warning.” Instead, it waited six minutes before breaking into the broadcast.

The station noted that it streamed live weather coverage on its website and gave updates with on-screen texts. But on reflection realizing “that seconds matter,” station officials now believe it “should have broken into football programming sooner.” Station officials promised to do everything in their power “to make sure this does not happen again.”
