I totally disagree, it is the first responsibility of a TV station to be responsible to the viewers. I obviously didn't see everything that transpired, but there have been plenty of times here where the local weather people have had to cut into shows. I can't speak of the nature of the storms or how long he was on their air, but if those storms were to gust up and cause damage, injury, or death, that station is going to look pretty stupid and irresponsible for not reporting it. Unfortunately, most people are ignorant when it comes to storms, so that's why the weatherman has to come on the air and go over severe storm procedure and to update what is going on.
Maybe that's just me, but I can think of an instance where we had a tornado outbreak here last fall where people were injured and they cut into programming. It would irk me to know people west and northwest of this area that weren't involved in the outbreak would be pissed because God forbid, they missed an episode of Oprah or something.
