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.
The National Oceanic and Atmospheric Administration (NOAA) has provided those of us in the southeastern to northeastern U. S. with an excellent risk assessment tool for hurricanes. See their “Historical Hurricane Tracks” page/search engine at http://csc-s-maps-q.csc.noaa.gov/hurricanes/viewer.html; to query their data (from 1878 in the case of Virginia) and see a map showing where major storms have passed through your area. You can query by several means, including zip code, which produces a very specific and detailed map of the location along with dates and degree of severity of the storms, as well as their names of the ones who were given them.
