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."

Detailed information, maps, and pictures from significant Arkansas tornadoes and tornado outbreaks utilizing the Damage Assessment Toolkit (DAT) database are provided here. Scroll down to view all tornado events or use the navigation above to jump to a particular tornado event. Note that this is NOT a comprehensive database of all Arkansas tornado events, but serves to highlight the significant events in recorded history, by not just the North Little Rock Forecast Office, but all NWS Offices who serve portions of the state of Arkansas, including NWS Tulsa, NWS Memphis, NWS Shreveport, and NWS Jackson.This database documents several Arkansas significant events within the DAT database, but not all events are represented. Map features including damage points, tracks, and swaths are interactive, and can be clicked within the map to see details, including damage pictures for some locations.

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 October 2010 tornado outbreak was the largest in Arizona history and was also notable for producing the highest count of tornadoes ever in a single event that took place west of the Continental Divide. At least nine tornadoes were recorded during the morning hours of October 6, 2010. The most active time was from 4:00 AM - Noon MST. The National Weather Service office in Flagstaff issued 28 Tornado Warnings, 25 Severe Thunderstorm Warnings, and 1 Flash Flood Warning during this event. Multiple tornadic storms repeatedly developed over the same locations in north-central Arizona, keeping the small area under a constant tornado threat for several hours. Large hail (up to baseball-sized) was reported. The duration, intensity, and number of tornadoes distinguished this event apart from any other event in history west of the Continental Divide and in Arizona.For a full event summary visit our event summary page: https://www.weather.gov/fgz/TornadoesOct2010Sources: https://www.google.com/earth/

All data displayed on this Dashboard is near real-time, automatically updating at regular intervals. Web Services used in the dashboard: (visit link to learn more about each service) IRWIN - The Integrated Reporting of Wildland-Fire Information (IRWIN) service is an investment intended to enable “end-to-end” fire reporting capability. IRWIN provides data exchange capabilities between existing applications used to manage data related to wildland fire incidents. IRWIN focuses on the goals of reducing redundant data entry, identifying authoritative data sources, and improving the consistency, accuracy, and availability of operational data.IRWIN can be thought of as a central hub that orchestrates data between the various applications. Users continue to utilize existing applications. Data is synchronized between participating applications to ensure the most current data is available in near real time. IRWIN supports conflict detection and resolution on all new wildfire incidents to support a unique record for each incident.NOAA nowCOAST - Provides web services of near real-time observations, analyses, tide predictions, model guidance, watches/warnings, and forecasts for the coastal United States by integrating data and information across NOAA, other federal agencies and regional ocean and weather observing systems (source).
