From Rebecca J. Rosen for The Atlantic:

This comes from hint.fm, a collaboration of data-visualization stars Fernanda Viégas and Martin Wattenberg. Their wind map provides a nearly real-time glimpse of the wind flow around the United States, based on hourly data drawn from the National Digital Forecast Database. “So,” they write, “what you’re seeing is a living portrait.” (It looks even better on their site, so definitely click through to see it in its full glory.)

The map is always beautiful, even without a hurricane’s massive force. Today, though, it can give you a sense of just how far-reaching are Isaac’s effects, just how much of the country can feel the winds, literally, of a storm in the gulf.

For contrast, on the Wind Map’s gallery page you can see some different wind patterns from earlier this year
