I've never played with satellite, so I can't weigh in much there.

I have a smartphone with a data plan that I can use to gain internet access even if the power is out, and in a pinch I can even use it to connect a laptop out to the internet. Thihs of course presumes the local cell towers aren't overwhelmed with traffic as they well be in an emergency.

I also have a pile of battery-powered radios and a pile of batteries. The main local AM station and several of the local FM stations are designated emergency broadcast stations with greater or lesser periods of built-in generator run time. They also happen to have real DJs most of the time, and a producer sitting around to cut in with local content if something happens in the middle of the night. Anytime a major event arises they are good about getting the word out quickly and thoroughly.
