A Brief History of a Tornado Warning
01/24/2010

**7.02pm** Yes, I've typed 2009 instead of 2010 in several places. LOL. I'll fix the map later.



The area above was placed under a Tornado Warning by the National Weather Service for a brief time this afternoon after radar indicated conditions favored the formation of a tornado in Henderson and Buncombe Counties in western North Carolina.

I posted a radar image of the vortex on Twitter via TwitPic.



Here is the way the regional map for the GSP Office of the National Weather Service looked at the time the Tornado warning was issued:


And here is the statement issued:
