Radar Derived Storm Paths from the 4/14/2012 Tornado Outbreak

[UPDATED: 4/17/2012 – 12am CT – Several National Weather Service Forecast Offices have completed preliminary storm surveys.  The product I created Saturday evening has been verifying very well, especially with the long-tracked storms.  Comparisons will be added for each tornado below.]

First off.. my thoughts and prayers are with all those impacted by today’s tornadoes, especially in Kansas, Oklahoma, Nebraska and Iowa.  I’ve put together path tracks of the tornadoes based on radar data.

I hope this has helped some people today save lives, and in the days to come, I hope it helps people recover faster from the storms.

Below is an interactive map that is based on spotter confirmed significant tornadic storms.  The points on the map UNOFFICIALLY depict the most likely areas where a tornado went based on radar products from the National Weather Service.  It will likely take several days for authorities in the area to fully assess the damage, but in the mean time, I hope this helps people as a starting point.  Once official damage surveys are released, I’ll be merging them into the map. Also, please note that while the radar may indicate a continuous path, detailed damage assessments and storm surveys may end up splitting these storms into separate tornadoes.

Communities will rebuild, but sharing this information may help people visualize the impact of the event, and hopefully spur people on to helping their fellow citizens.  Again, my thoughts and prayers go out to so many people, especially those in the Kansas and Oklahoma.
