I would prefer the weather radio at home, smart phone app, and IPad app that sounds versus a siren. One: you can hear it better, and, Two: it is portable and you can than view it with the radar for more information. Probably a few of you have an IPad or smart phone that can be used. The phone is nice since it warns you IF you are not home also. Such as the golf course, when the weather is not stormy, but looks ominous, shopping, squares, indoors elsewhere. Ours all went of yesterday. We looked at the radars on the IPad and found the storms were south of TV heading east. north we had basements, but those that don't they tell you go to an interior room in the house with no windows. Dragging a queen mattress is a bit much too.
I was a weather spotter north (Skywarn) for the area so I also was one when it got bad, was outdoors looking and reporting, versus in a room until it was no longer safe. There must be weather spotting classes around here? If not, the local stations should start them. It is a good training session and describes what to look for, what to do, when to do it, and much more. You can than volunteer to be a spotter. They contact you (phone/text) and ask if you are available to spot the area. They than used the spotters for more information and videos if possible.
