Google has announced Google Public Alerts, a platform designed to bring you relevant emergency alerts when you're searching on Google.
If a major storm is headed your way, Google wants to be your go-to information source. The Google Crisis Response team wants to alert users about when a storm will strike, how bad will it be, and what resources are available to help in the current situation.
Assuming you have cell service or Internet access during a major weather event, the emergency information will be available online with easy to use online tools. Google has teamed up with several weather, public safety, and national foundations such as the U.S. National Oceanic and Atmospheric Administration (NOAA), the National Weather Service, and the U.S. Geological Survey (USGS), with all their data being accessible online the moment it hits any one of their sites.
For example, if you Google [flood Indiana], this will trigger a Flood Warning Google Maps alert, which appears above all the other map information on the page.
If you click on "more info" you will see a page detailing out everything about the flood warning alert, along with everything that Google has about the possible or current flooding. You will also get a link to the source of the information, in this case The National Weather Service.
If you're located in the area of the alert, your area will be listed first. If you aren't located in the area of the alert, you'll see the areas listed with the greatest severity based on your search query. To see a breakdown of every alerts based on your geographical location, you can visit the Google Alerts page.
