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."

Historical tornado records for Carver County, Minnesota from 1950 to present.

A database of verified tornado tracks across Canada has been created covering the 30-year period from 1980 to 2009. The tornado data have undergone a number of quality control checks and represent the most current knowledge of past tornado events over the period. However, updates may be made to the database as new or more accurate information becomes available. The data have been converted to a geo-referenced mapping file that can be viewed and manipulated using GIS software.

The NWS Atlanta Tornado Climatology Dashboard web mapping application was created to provide a resource for critical historical tornado data for partners across the county warning area (CWA). The web mapping application utilizes a dashboard of Storm Prediction Center (SPC) tornado climatology from 1950 to 2021 as well as Damage Assessment Toolkit (DAT) polygons and paths to provide information about past tornados. The Tornado Climatology Dashboard web mapping application was created based on requests from local partners about historical tornado paths. This dashboard will be updated to include new tornados as the data becomes available each year. This web mapping application also contains some resources on datasets as well as the Fujita and Enhanced Fujita Scales.

The 27 April 2011 severe weather outbreak included 62 tornadoes across northern and central Alabama, leading to one of the largest post-event survey operations in history. The enormity of the task faced by National Weather Service surveyors required extensive planning in an attempt to ensure that every tornado was documented. Moderate- and high-resolution satellite imagery can support the assessment process. Normalized difference vegetation index (NDVI) imagery from the Moderate Resolution Imaging Spectroradiometer, Enhanced Thematic Mapper Plus, and Advanced Spaceborne Thermal Emission and Reflection Radiometer was used to assess satellite-based capabilities to detect tornado damage tracks, expanding upon previous studies of tornado-track detection. Of the tornadoes that were officially documented and surveyed in Alabama, 22 (32.4%) were identified at least in part by a simple visual inspection of single-day NDVI imagery. Detection of satellite-based damage tracks improved for tornadoes with estimated maximum damage of EF-2, with portions of 21 (65.6%) paths identified. Lengths of satellite-detected tornado tracks compared favorably (R2 = 0.88–0.93) to official survey measurements, but maximum estimated widths compared less favorably (R2 = 0.39–0.52). Longer-term NDVI change and image-enhancement techniques, such as principal component analysis, can improve visual inspection. Overall, this study demonstrates that near real-time access to moderate- and high-resolution imagery may support survey activities, particularly in well-vegetated regions where spectral bands and high spatial resolution allow for detection of vegetation damage resulting from severe weather.
