Radar-Based Maps of the Henryville, IN Storm Tracks


NWS Louisville Statement on the Challenges in Damage Assessment for the Henryville, IN Tornado.

UPDATE: MARCH 6 – The National Weather Service in Louisville has published their initial findings including descriptions of the areas impacted.  That information is available at: NWS Louisville Damage Surveys – March 2, 2012.

Also, I have put together an initial version of an interactive web-map at ArcGIS.com that combines information from the second map below with the damage path information from the NWS in the link above.  The map is accessible at: Web Map of the Henrysville damage path and radar based-storm tracks at ArcGIS.com

ORIGINAL POST: March 4, 2012 – 630pm ET:

The past two days have been full of media reports, tweets and information being shared on the tornado outbreak that occurred on March 2nd, 2012 affecting towns like Henryville, IN.  As you can see from the statement below from the NWS Louisville Forecast Office, there were two supercell storms that impacted the area, with the first one producing the tornado that most people are talking about.  There was in fact a second storm behind the first one that also produced tornadoes and tornadic damage.  To make things more complicated for damage assessment teams, the paths essentially paralleled one another, and even crossed in places, making it difficult to attribute the damage to one storm versus the other.

I’ve put together the following the following map based on the NWS Radar information from the March 2nd tornado outbreak.  The map shows the paths of the two storms and paint the clear challenge that the NWS professionals have in identifying and differentiating between the two damage paths.   When more information is available from the NWS Louisville Office, links to their maps and storm summaries will be attached.

Storm tracks do NOT mean that a tornado was on the ground the entire time, but they point to the areas where the storms tracked.
