Tornadoes are wreaking havoc across the continental U. S. this month, even in states not usually considered to be at high risk, such as Virginia. The jury appears to be still out on why–global warming? Better detection technology and reporting? Probably some of both. Here’s an excellent site provided by NOAA’s National Weather Service (NWS)–their Storm Prediction Center: http://www.spc.noaa.gov/. On the site, severe weather warnings are available from the link above the map. If you don’t have a weather radio to give you alerts about approaching storms, you can keep an eye on the situation nationally or in your locality via this NWS site.
