Local churches in small, rural communities know everybody and where they live. They are good donation drop-off sites. Quite a few now have generators and are preparing food. If the churches haven't seen or received info about their people, groups are using ATV's or going on foot. For many of the inhabitants of the Appalachian Mountains there are no paved roads (even before Helene). There's paths, trails, and maybe gravel roads (single lane). Ah, almost forgot: this is also moonshine territory so LEO's, government, and strangers are viewed as trespassers and may be shot.
