Google Public Alerts
https://www.google.org/publicalerts

Google Public Alerts is Google’s new platform for disseminating emergency messages such as evacuation notices for hurricanes, and everyday alerts such as storm warnings. They aim to show relevant weather, public safety and earthquake alerts from the US National Weather Service, the US Geological Survey (USGS), and AMBER alerts when you search on Google Search, Google Maps, and when you activate Google Now on your Android device. Google Public Alerts is a project of the Google Crisis Response team, supported by Google.org, which uses Google’s strengths in information and technology to build products and advocate for policies that address global challenges. They hope Google Public Alerts provides the public with information it needs to make informed decisions in times of crisis. While they can’t guarantee that you’ll see every alert when using Google services they are doing their best to show what’s important when you need it, and hope that Google Public Alerts is a useful additional source of information. Google Public Alerts currently shows weather, public safety and earthquake alerts from the US National Weather Service, US Geological Survey (USGS), and AMBER Alerts.
