More than 28 million people are under a blizzard warning in the Northeast, the Weather Channel estimates, awaiting a storm that the National Weather Service in Boston is calling "crippling and potentially historic."
If you'd like to take a look at who's supposed to get what, the folks at ESRI (makers of ArcGIS) came up with this map combining data from the National Weather Service, National Oceanic and Atmospheric Administration and AccuWeather:

And for a look at what's happening in social media surrounding the storm, this map tracks mentions on Twitter, Flickr and YouTube.
The social media map was created with a standard ArcGIS Online Web app template, according to Robby Deming at Esri. "Once you’re done creating a Web map, you simply publish the map to the Public Information web app template and it automatically handles the social media side of things," he explained in an email.
