Donate to the American Red Cross and help tornado victims

(CNN) -- Much of Moore, Oklahoma, which is just outside of Oklahoma City, is now a devastated pile of rubble.

The search and rescue mission continues after a massive tornado touched down Monday afternoon. CNN affiliate KFOR reported that at one time, the tornado was estimated to be at least 2 miles wide, and the National Weather Service is also saying the scale of the tornado is at least EF4. This is the second most severe classification of tornado.

It is clear the days ahead are grave for the people of Oklahoma and the need for help will be immense.
