I turned them off. I use Weatherbug Elite, and saw a warning - the warning was for farther south. It did not impact where I live so I would have been very annoyed at a audible warning.
I checked the NWS and the blizzard warning overlay was for further north and east. Colorado can have rain in one section of town and snow in another. General predictions can be off. They would have to go by neighborhood elevation, and most people don't know the elevation.
If I see a weather change, I check the NWS online immediately.
