Because of the various warnings available and the ability to select individual counties, it's already difficult enough. Don't complicate with all kinds of software, cell phones and emails.
A quality weather radio will give you the information you need without jumping through a bunch of hoops. I've had my Reecom radio for over 10 years. It has always performed flawlessly even with the standard, built-in antenna. I have it programmed for my county and, because most of our storm activity moves in from the west, I have the adjacent western counties included. It has a battery backup that also works just fine. The only attention it gets from me is an occasional dusting.
If one doesn't have a life and needs something to do, then yes, jump through the hoops. If you want something to warn you of impending storms, etc., get a decent quality weather radio and let it do it's job.
