Live about half an hour ago. That video of the candle factory a few posts back shook me: "mass casualties," indeed.
I have seen some tweets criticizing him for not giving specific emergency instructions, phone numbers, shelters, and the like. The disaster is so widespread, though; it's bigger than a typical weather event. Local emergency managers are doing that. Looks to me like Kentucky is going with the same type of crisis communication that volcanologists recommend for managing their eruption crises, for example, giving an overview of the threat situation, telling people exactly what is being done, and reassuring everybody they will get by it. All this, through a single source, in this case, the governor. It's a real good way to keep the public calm and up to date, and to help them deal with it all.
On La Palma, local government says "Stronger than the volcano." Here, it's good old US common sense, grit, neighborly aid, and "Kentucky Strong" (and Arkansas, and Tennessee, and everywhere else that the tornadoes have touched).
