Doing something like that on VHF is utterly idiotic if you need to cover a large area, unless it's as flat as a snooker table.
Do it on SW, around 6MHz, and you'll cover a 300-mile radius with 50 watts.

So the inherently local nature of VHF complements the inherently local weather alerts. Floods and tornadoes are not an issue at a distance of 300 miles.
