Currently filtered for Storm Date is after 12/1/2023Purpose: This is a feature layer of tornado swaths for the NWS Damage Assessment Toolkit.The National Weather Service (NWS) Damage Assessment Toolkit (DAT) has been utilized experimentally since 2009 to assess damage following tornadoes and convective wind events. The DAT is a GIS-based framework for collecting, storing, and analyzing damage survey data, utilizing the Enhanced Fujita (EF) scale for the classification of damage. Data collected from individual locations via mobile device are transmitted to a central geospatial database where they are quality controlled and analyzed to assign the official EF rating. In addition to the individual point, the data are analyzed to generate track centerlines and damage swaths. High resolution satellite imagery and radar data, through partnership with the NASA Short-term Prediction Research and Transition Center, are also available to aid in the analysis. The subsequent dataset is then made available through a web-based graphical interface and GIS services.Here is the full REST service: https://services.dat.noaa.gov/arcgis/rest/services/nws_damageassessmenttoolkitGeoplatform website: https://communities.geoplatform.gov/disasters/noaa-damage-assessment-toolkit-dat/More InformationWelcome to the National Weather Service Damage Assessment Toolkit. Data on this interface is collected during NWS Post-Event Damage Assessments. While the data has been quality controlled, it is still considered preliminary.

Tornado TracksThis feature layer, utilizing data from the National Oceanic and Atmospheric Administration (NOAA), displays tornadoes in the United States, Puerto Rico and U.S. Virgin Islands between 1950 and 2024. A tornado track shows the route of a tornado. Per NOAA, "A tornado is a narrow, violently rotating column of air that extends from a thunderstorm to the ground. Because wind is invisible, it is hard to see a tornado unless it forms a condensation funnel made up of water droplets, dust and debris. Tornadoes can be among the most violent phenomena of all atmospheric storms we experience. The most destructive tornadoes occur from supercells, which are rotating thunderstorms with a well-defined radar circulation called a mesocyclone. (Supercells can also produce damaging hail, severe non-tornadic winds, frequent lightning, and flash floods.)"EF-5 Tornado Track (May 3, 1999) near Oklahoma City, OklahomaData currency: December 30, 2024Data source: Storm Prediction CenterData modifications: Added field "Date_Calc"For more information: Severe Weather 101 - Tornadoes; NSSL Research: TornadoesSupport documentation: SPC Tornado, Hail, and Wind Database Format SpecificationFor feedback, please contact: ArcGIScomNationalMaps@esri.comNational Oceanic and Atmospheric AdministrationPer NOAA, its mission is "To understand and predict changes in climate, weather, ocean, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources."

Tornado tracks display the total length of tornado paths and are only shown at the largest extents. Tornado strength shown by its fujita scale, is displayed by color and point size. Stronger storms are shown with larger symbols and brighter colors. Pop-ups contain relevant tornado information including date, time, fujita scale, fatalities, injuries, tornado track length and tornado width. All data was provided by the National Oceanic and Atmospheric Administration.

NWS Atlanta tornado damage paths accessed from NOAA/NWS Damage Assessment Toolkit (DAT) are mapped from 2011 when the DAT application was implemented operationally for post-event assessment at NWS Atlanta to the present date. DAT tornado paths show a more detailed storm track as they are created by connecting the centerline of damage indicator locations logged using the DAT mobile GIS application during post-event tornado surveys. The paths are classified by the highest Enhanced Fujita (EF) Scale magnitude the storm achieved. Because of this, the EF magnitude of the tornado may not be reflective of the actual strength of the tornado at a particular location. The DAT polygon data is considered more useful to explore the evolution of the strength of the tornado along its path.While data in the DAT have been quality controlled, this data is considered to be preliminary while official storm data can be found using a web-based GIS service at https://www.ncdc.noaa.gov/IPS/sd/sd.html. In addition to DAT storm path data, DAT polygon and point data can be accessed at https://apps.dat.noaa.gov/stormdamage/damageviewer/. This layer supports the NWS Atlanta Damage Assessment Toolkit Tornado Paths (2011-Present) map, which can be accessed at https://arcg.is/1a1yTi0. The NWS Atlanta Damage Assessment Toolkit Tornado Paths (2011-Present) map supports the NWS Atlanta Tornado Climatology Dashboard web map application, which can be accessed at https://arcg.is/1yTWuz.
