Some airports also have public phone numbers to get weather information, could come in handy to know if you're-for example, living in tornado alley and a system rolls through that knocks out power and cellular service.
If you have a working landline phone, calling a nearby airport could be your only way to know the latest conditions and if it's safe to go outside.
My elderly father is living with my sister's family. To find out if it's safe to venture outside they tie a rope to him and push him out the door.
