Comment An Alternative to Wireless Emergency Alerts (Score 1) 382
These alerts come from a system controlled by FEMA and less than 200 local governments are currently using that system. So here's a way to get better, more relevant safety alerts and still get a good night's sleep: sign up for your local emergency alert service.
Thousands of counties and cities across the US have them. And you can sign up for yours at http://www.usnear.org./
Choose "text messages" and they will come in like normal texts (not a 3 alarm fire alert!). Which means they won't override your DND settings.
