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."

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. Official statistics for severe weather events can be found in the Storm Data publication, available from the National Centers for Environmental Information (NCEI) at: https://www.ncdc.noaa.gov/IPS/sd/sd.html Questions regarding this data can be addressed to: parks.camp@noaa.gov.

This ArcGIS Feature Service contains the two tables that are used for creating all the tornado points and lines on the Florida ENSO Tornado Map. The two layers 'TornadoPoints' and 'TornadoTracks' come from these two tables and contain all of Florida's documented tornadoes from 1950-2022. The additional layers with '_EF#' at the end of the names are layers for each tornado that obtained those F/EF intensities in Florida (only one F-4 track on record in Florida, no F/EF-5s). Data from NOAA/NWS SPC tornado archive found at https://www.spc.noaa.gov/wcm/#data.

This is part of the work done for the response to the Dallas Tornado of 2019. This data layer is a remnant of the extensive efforts carried out in response to the devastating Dallas Tornado of 2019. During the aftermath of the tornado, the grid was established as a crucial tool for coordinating cleanup operations, mapping affected areas, and managing resources efficiently. Although the cleanup has long been completed, the grid remains accessible as a reference layer. It serves as a historical record and a resource for planning, analysis, or similar disaster response efforts in the future. Its continued availability ensures that the valuable lessons and data from the 2019 tornado response can inform and enhance preparedness for future events.

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 the 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 Polygons (2011-Present) map, which can be accessed at https://arcg.is/1a1yTi0. The NWS Atlanta Damage Assessment Toolkit Tornado Polygons (2011-Present) map supports the NWS Atlanta Tornado Climatology Dashboard web map application, which can be accessed at https://arcg.is/1yTWuz.

National Weather Service Storm Survey information regarding the tornado outbreak of December 10-11, 2021. Included are storm survey damage points with pictures where available, tornado damage paths, and estimated damage swath information where applicable. ALL DATA SHOULD BE CONSIDERED PRELIMINARY.

Description:This polygon feature layer represents tornado risk zones across the United States, derived from the ASCE 7-22 Hazard Tool published by the American Society of Civil Engineers (ASCE). The data is based on the ASCE 7-22 Standard, which includes updated criteria for structural design considering tornado hazards. This feature layer is also part of the ASCE Hazard Tool Recreation in Experience Builder.The polygons define areas with differing levels of tornado intensity risk, determined through historical tornado track data and probabilistic modeling. Each zone corresponds to a specific design-level tornado wind speed (in miles per hour), which engineers use to design critical and essential facilities.Data Source:This dataset is sourced from the ASCE 7-22 Hazard Tool and is accessible via the ASCE ArcGIS REST Service:https://gis.asce.org/arcgis/rest/services/ASCE722Units:Design-level tornado wind speeds are provided in miles per hour (mph).Usage Notes:This data is intended for planning and structural design applications, particularly for essential facilities and structures requiring enhanced performance under extreme wind events. Users should refer to the official ASCE 7-22 documentation and consult with licensed engineers for code-compliant design. Local conditions may necessitate additional site-specific evaluation.Credits:American Society of Civil Engineers (ASCE)
