Today's Outlook

Today's Tornado Outlook (Loading date...)

This outlook map shows areas where tornadoes are most likely to form today, based on data from NOAA's Storm Prediction Center. Colored areas show the probability of a tornado within 25 miles of any point. Even 5% is significant — that's 5x normal odds. Dashed outlines show Conditional Intensity Groups (CIG): CIG1 = brief/weak tornadoes, CIG2 = strong, CIG3 = violent/long-track.

Tomorrow's Tornado Outlook (Loading date...)

This outlook map shows areas where tornadoes are most likely to form on Day 2 (tomorrow), based on data from NOAA's Storm Prediction Center. Colored areas show the probability of a tornado within 25 miles of any point. Even 5% is significant — that's 5x normal odds. Dashed outlines show Conditional Intensity Groups (CIG): CIG1 = brief/weak tornadoes, CIG2 = strong, CIG3 = violent/long-track.

Understanding Our Tornado Tracking Maps

Tornado Path delivers live tornado warning tracking across the United States 🇺🇸 and Canada 🇨🇦 through three specialized interactive maps. Using official data from the National Weather Service (NWS) and Environment and Climate Change Canada (ECCC), each map is designed to help you stay informed and safe during severe weather.

Live Tornado Warnings Map

Displays active tornado warnings with radar and motion paths.

What is a Tornado Warning?

A tornado warning means a tornado has been detected by weather radar or spotted by trained observers. It is not a prediction - it means a tornado is either occurring or is expected. When a warning is issued for your area, take action to protect yourself and others.

How To Use

  • • Toggle between radar and tornado risk layers
  • • Adjust opacity for better visibility
  • • Play/pause radar animation to track storm movement
  • • Click on storm markers to see movement details

Why It Matters

Combining tornado warnings with radar helps you visualize active threats and better understand storm movement in your area.

Recent Expired Tornado Warnings

Shows tornado warnings from the past 48 hours to analyze recent patterns.

How To Use

  • • Review past warning polygons to see affected areas
  • • Compare with current conditions using the map style selector
  • • Click on any warning to view detailed information
  • • Use radar overlay to see how storms tracked

Why It Matters

Historical data helps identify patterns and verifies whether areas that received warnings were actually impacted.

Tornado Outlook Map

Displays tornado probability areas from the NOAA Storm Prediction Center.

Today & Tomorrow's Forecasts

We provide two detailed outlook maps: today's forecast showing current risk areas, and tomorrow's forecast to help you plan ahead. Both maps use official Storm Prediction Center data to show where tornadoes are most likely to develop.

How To Use

  • • Toggle between map styles to see different perspectives
  • • Zoom in and out to see detailed risk areas
  • • Click on any area to see more information
  • • Use the legend to understand risk levels

Why It Matters

Understanding these risk areas helps you prepare for severe weather and stay safe.

Map Controls Explained

1

Radar Controls

Our radar layer shows precipitation intensity from light rain (blue) to intense storms (red/purple).

  • • Animation controls let you play through the last hour of radar to track storm development and movement direction
  • • Opacity control helps blend radar with other map features for optimal visualization
2

Tornado Risk Controls

The risk layer displays official Storm Prediction Center tornado probability zones for the current day.

  • • Higher percentages (darker colors) indicate greater tornado probability for that area
  • • Overlay both radar and risk layers to see if storms are developing in high-probability areas

Our Data Sources

Tornado Path combines multiple official data sources from the United States 🇺🇸 and Canada 🇨🇦 to provide comprehensive tornado monitoring:

🇺🇸 National Weather Service Warnings

Official US tornado warning polygons with precise geographic boundaries and storm motion data

🇨🇦 Environment and Climate Change Canada

Official Canadian tornado warnings and severe weather alerts with geographic coverage areas

RainViewer Radar

High-resolution radar imagery showing precipitation intensity and storm cells

MapLibre GL Visualization

Open-source WebGL-powered mapping platform for interactive visualization and geographic analysis

Data is automatically refreshed to ensure you have current information available.

Tornado Safety Tips

  • • When a warning is issued for your area, seek shelter in a basement or interior room
  • • Stay away from windows and exterior walls
  • • If you see a tornado approaching, never try to outrun it in a vehicle
  • • Monitor our live maps and local weather alerts during severe weather events
