Old Weather Radio Technology Still Most Trusted for Tracking Monsoons:

Weather Radio is the steady stream of rough messages broadcast 24/7 and picked up by your favorite radio stations when the weather turns. They're a nearly daily occurrence in Arizona right now, warning of flash flooding in Douglas, winds in Tucson, and severe storms just outside Phoenix. This recent broadcast in Nogales warned people to move to the first floor of whatever building they were in. And if it sounds a little garbled, there's a reason for that. Dan Leins is a meteorologist with the National Weather Service in Tucson. Scientist and meteorologist Dan Leins demonstrates the NOAA Weather Radio at the National Weather Service in Tucson. "They got their start with a person who would go live on the radio when they had active weather going on. They would either speak live or do recordings on tape. And that would play back over and over and over again. That would run 24/7 if there was active weather in the middle of the night," Leins saidIt's a technology from the last century. In fact, before Twitter, the National Oceanic and Atmospheric Administration Radio All Hazards -- or, Weather Radio -- was intended as a way for the president to reach the country. "If there's a natural disaster, if there was a nuclear disaster, the system was designed to pick up broadcasts like that and redistribute them nationally instantly. That was one of the main purposes that NOAA weather radio all hazards was deployed."
