Monitoring Tornadoes with DisasterAWARE

Tornadoes are among the most destructive natural hazards in North America, with the vast majority occurring in the United States. Each year, the U.S. experiences over 1,000 tornadoes, resulting in approximately $1 billion in damages, over 1,500 injuries, and around 80 fatalities.

DisasterAWARE provides real-time monitoring and impact analysis to help organizations anticipate and respond to these fast-moving threats. Our platform integrates authoritative data from the U.S. National Weather Service (NWS), Canada’s Meteorological Service, and other trusted sources to deliver accurate and timely tornado intelligence.

With advanced alerting, severity modeling, and exposure analysis, DisasterAWARE empowers emergency managers, insurers, and business continuity leaders to protect assets and ensure operational resilience when seconds count.

Situational
Awareness Products

When a tornado is detected, DisasterAWARE automatically generates a Situational Awareness Report to provide a clear, actionable snapshot of the threat. Each report includes:

Alert Summary with the tornado’s type, severity, and affected area.
Administrative Boundaries and Urban Area Context to support rapid operational planning
Issued Warning Information from the authoritative agency—such as the U.S. National Weather Service—including the time, location, and expected movement of the tornado.
Visual Map Overlay showing the warning polygon and storm location using Doppler radar data.
Impacted Areas, listing counties, towns, and key infrastructure (e.g., Little Rock AFB) in the tornado’s projected path.
Situational  Awareness Products

These reports are automatically updated with every significant change to the tornado’s characteristics—such as a shift in location or an updated track—ensuring users have the most current information at all times.

Hazard
Severity Calculation

Hazard  Severity Calculation

DisasterAWARE uses the severity classifications provided directly by the authoritative issuing agency, ensuring consistency with the standards of the region where the tornado threat is occurring. These agencies include the U.S. National Weather Service (NWS), Environment and Climate Change Canada, the Australian Bureau of Meteorology, and others.

Tornado hazards are typically classified into two severity types:

Tornado Watch

Indicates that conditions are favorable for the formation of tornadoes in or near the watch area. Watches usually cover a broad region and provide advance notice of potential tornado activity. Users should remain alert and review emergency protocols.


Tornado Warning

Indicates that a tornado has been visually confirmed or detected by radar and is either occurring or imminent. Warnings are specific to affected areas and timeframes and call for immediate protective action.

DisasterAWARE continuously monitors for updates from these agencies. Any change in severity—such as an escalation from watch to warning—automatically triggers a new alert, updated exposure analysis, and refreshed situational awareness products.

Notification
and Exposure Areas

Notification  and Exposure Areas

DisasterAWARE provides notification and exposure areas as defined by the issuing authoritative agency, such as the U.S. National Weather Service (NWS), Environment Canada, or Australia’s Bureau of Meteorology. To reduce alert fatigue and improve clarity, DisasterAWARE intelligently clusters related messages from multiple forecast officeswithin the same agency when they refer to the same tornado event. This allows users to receive a unified alert, even when the hazard spans multiple jurisdictions.

Notification Areas (SmartAlert)

Based on the official SAME (Specific Area Message Encoding) codes or equivalent regional standards, these define where alerts are actively pushed to users.

Exposure Areas

Represent zones at risk from the tornado. Exposure is further classified by severity—Moderate, Strong, or Severe—depending on the threat level. DisasterAWARE normalizes these severity levels across all supported agencies, providing a consistent experience for users regardless of the source.

This approach ensures organizations receive accurate, consolidated, and easy-to-act-on intelligence, even when hazards are reported by multiple regional authorities.

Asset Protection
And Exposure Reporting

DisasterAWARE includes powerful Asset Protection tools that help organizations monitor how hazards—such as wildfires—affect the people, places, and infrastructure they care about most.

Users can define asset classes by either:

  • Connecting to an ArcGIS map service as the source of their asset data, or
  • Connecting to an ArcGIS map service as the source of their asset data, or

Each asset class can be customized with:

  • Synchronization settings to control how often data is refreshed from the ArcGIS source
  • Notification buffers that define how close a hazard must be to trigger an alert
  • Custom fields for enhanced reporting and targeted notifications

Once loaded, assets can be viewed in two ways: through the Notification Panel, or by enabling their associated map service layer under the User folder in the Layers Panel.Assets can be user-owned or shared at the organization level. Organizations with multiple teams can also set up Sub-Organizations, each with their own asset classes and notification rules—providing flexibility in how asset data is managed and accessed across departments.

For each asset class, users can define non-user contacts—such as building managers or emergency coordinators—who should receive notifications when a hazard threatens specific locations. These contacts receive email alerts with detailed hazard information, ensuring they stay informed even if they don’t actively use the platform.

DisasterAWARE also generates Asset Exposure Reports, which summarize:

  • The number and types of assets affected by a hazard
  • Additional impact metrics defined by the user, such as the number of employees at risk, total replacement value, or other key indicators

These features help organizations stay ahead of emerging threats, understand the geographic relationship between hazards and their assets, and quantify their total exposure—supporting faster, more informed decisions during critical moments.

Additional Data Layers

In addition to core tornado alert layers, DisasterAWARE offers a range of supporting data layers that enhance situational awareness and help assess potential impacts. These include:

These layers provide insight into where tornadoes are most likely to occur, and which areas are under active alert:

  • circle check icon
    Tornado Probability – Day 1 (USA) – shows areas at elevated risk for tornado development based on forecast models
  • circle check icon
    Tornado Watches (USA) – identifies regions where tornado formation is possible and conditions are favorable.
  • circle check icon
    Tornado Warnings (USA) – highlights areas where a tornado has been observed or indicated by radar, requiring immediate action
  • circle check icon
    Doppler Radar (USA) – visualizes storm structure, intensity, and rotation in real timePrecipitation Forecast (GFS) – useful for tracking storm activity and rainfall associated with tornadic systems
