FEMA has some really helpful information on disaster planning. You can find this information at http://www.fema.gov/areyouready/. The information covers the following natural disasters:
- Thunderstorms and Lightning
- Winter Storms and Extreme Cold
- Extreme Heat
- Landslide and Debris Flow (Mudslide)
I also came across this picture on line today. It was submitted by Ryan Crim and depicts a tornado behind Huston's First Baptist Church. The picture was found on Huntsville Times.
