Fortunately I am in a market where the better TV cluster has three graduate meteorologists, and one of the works with a local radio station too. But in the event of a major quake or extreme flooding with total power loss, there would be no accessible TV and I am not sure how much backup any of the radio stations have.The cluster where I worked that had its own radar and meteorologist is now owned by Cumulus, which canned the meteorologist in the Great Headroll of 2008 and 2009. It has been using TV audio ever since. It's a downgrade, but, when I'm in my basement shelter during a tornado warning, I still get a good picture of what’s going on and where. I agree with you that “you can see the damage right now” is irritating to hear on radio, but I'm usually turning off the radio and going back upstairs to watch the coverage on TV after the storm blows past my house.
We have to keep in mind that the radio industry is working with about 30% of the revenue it had in 2000; even then it was split in more ways due to translators and Docket 80-90 more than doubling the stations in the market.
