4/13 – 1028pm CT – Added link to NWS Norman preliminary UNOFFICIAL track map from @NWSNorman
4/13 – 928pm CT – Updated interactive map to include links to media video and photo of damage with locations. The locations verify quite well with the initial map points
It’s incredible to think of how today progressed…. First I shared a presentation on this topic to several of my peers around the country to share a methodology with the hopes of helping people tomorrow and in other tornado outbreaks, and the next thing I know, I’m talking to my brother in Oklahoma who is trying to get home to Norman after school, with a tornado warning for his home town. It’s amazing to see the impact of how technology and information can be brought together to help protect lives. I ended up helping guide him home to keep out of the storm while the tornado passed less than 1/2 mile from his house, telling him to stay put and keeping him out of harm, but still guiding him home. Thankfully everyone in the family is safe, but it’s incredible to know that it makes a difference so close to home.
With that said, here is the preliminary map that I just put together that is based on the KOUN, KTLX, TOKC radar sites and used the NCDC Weather/Climate Toolkit to create the points. The map also uses a template from ESRI’s ArcGIS Online. Clicking on the link below will allow you to interact with the map showing aerial photography as well as road maps of the area. Thankfully it wasn’t worse.
Please note that NOT ALL points depict where a tornado was on the ground, but the points do depict the areas on radar that had a greatest indicator of where a tornado was possibly or likely on the ground.
