Good news for people with Android phones!
There's a great app called iMap Weather Radio that has only been available for iPhones for the longest time. It uses the GPS location in your phone to give you weather alerts and warnings based on your location (as long as you're close enough to a cell tower to get data), and it allows you to enter a number of other addresses so that you can get weather alerts for, say, your house or your relatives. I think it has some other nice features, too, like radar and such.
Anyway, they just released an Android version of it at a discounted price. If you're in an area that doesn't get very good NOAA weather radio coverage or if you spend a lot of time outside away from the tv/radio, I think this is a good app to have. You should be able to search for it in the App Market (I think it's called Google Play now?).
