Google Introduces New Emergency Resources in Response to Sandy - NYTimes.com

In case of emergency, follow the people with the latest Android devices...

"On Monday night, the company introduced the new service, public alerts, to show warnings about natural disasters and emergencies based on information from government agencies like Ready.gov and the National Weather Service. Google said it had planned to introduce the service later, but sped up the process in response to Sandy. In the future, it will add alerts from other services, like Nixle, which publishes messages from the local police.
The alerts show up in response to searches on Google.com and Google Maps, and appear unprompted on the cellphones of people with the latest version of Android, through Google Now."
