Tornadoes, floods, weather crises: where to learn more about them?

There are lots of weather sites online that are excellent resources, like the federal government's NOAA site. This library related blog recently posted a very helpful list of online weather resources. Have a look too at our Earth Science research guide, which has an extensive meteorology section. The photo here is of the great Mississippi River flood of 1927, a flood many are worried might come again this year due to high water levels and incessant rain in that region. We have many books on meteorology in the collection too, including one on that flood of 1927.
