Why We're Different From Every Other Weather Site
2-5 Minutes Faster
We get tornado warnings before they appear on other major weather websites and apps.
Real-Time Updates
We instantly show updates, cancellations, and extensions. Other sites only show the original warning.
🇺🇸 🇨🇦 Full Coverage
Complete tornado tracking for both the United States and Canada with real-time warnings from NWS and ECCC.
Critical Information Other Sites Miss
When meteorologists update a tornado warning with new information - like direction changes, speed updates, or area expansions - we show those changes immediately. Most weather sites never update their warnings at all, leaving you with outdated, potentially dangerous information.

Real-Time Warning Updates: What Other Sites Miss
Here's the shocking truth: when the National Weather Service (US) or Environment Canada (Canada) updates a tornado warning, most weather websites never show those updates. They display the original warning and leave it unchanged until it expires, even when critical new information becomes available.
What Other Sites Do
- • Show only the ORIGINAL warning text
- • Never update when storm track changes
- • Miss cancellations (show expired warnings as active)
- • Ignore area expansions and extensions
- • No real-time storm movement information
- • Leave you with outdated, dangerous information
What Tornado Path Does
- • Show EVERY update in real-time
- • Instant storm track and speed changes
- • Immediate cancellation notices
- • Live area expansions and time extensions
- • Real-time storm movement vectors
- • Always current, life-saving information
Types of Updates We Track in Real-Time
Cancellations
When storms weaken or dissipate, we immediately remove them from active tracking
Extensions
Time extensions when storms persist longer than initially forecast
Track Changes
Direction and speed updates as storms evolve and move
Area Expansions
New counties and zones added as storms grow or change path
Severity Updates
Changes in threat level and storm characteristics
Confirmed Reports
When radar-indicated warnings become tornado-confirmed warnings
🚨 Real Example: What You Miss on Other Sites
US Example: A tornado warning is issued at 3:00 PM for a storm moving northeast. At 3:15 PM, the NWS updates the storm track to southeast toward a different town. At 3:25 PM, it's cancelled as the storm weakens.
Canadian Example: Environment Canada issues a tornado warning for southwestern Ontario at 2:00 PM. At 2:20 PM, they extend the warning to include additional counties. At 2:35 PM, they cancel the warning as the storm dissipates.
Other weather sites: Show only the original warnings until expiration, missing all updates.
Tornado Path: Shows every update immediately as they happen in both countries.
How We Get Tornado Warnings Faster
Most weather websites and apps get their tornado warnings from the same sources: the National Weather Service's public API for the US and Environment Canada's public feeds for Canada. But there are faster ways that emergency services have been using for years in both countries.
Standard Weather Apps
- • Use public NWS API (US) and ECCC feeds (Canada)
- • Data processed through multiple layers
- • 2-5 minute delay from issuance
- • Same as other major weather sites
- • Only get initial warnings - no updates!
Tornado Path
- • Direct NWS Open Interface (US) & ECCC CAP feeds (Canada)
- • Same feeds as emergency services in both countries
- • Warnings within 30 seconds of issuance
- • Redundant backup systems for reliability
- • Real-time updates, cancellations, and extensions!
Understanding US & Canadian Warning Systems
Both the United States and Canada operate sophisticated warning distribution systems, each with priority feeds for emergency services and public feeds for general consumption:
🇺🇸 US: NWS Open Interface (OI) - Priority System
This is the high-priority data feed that the NWS uses to distribute warnings to:
- Emergency Management Agencies
- 911 Dispatch Centers
- Emergency Alert System (EAS) broadcasters
- Wireless Emergency Alerts (WEA) systems
- Critical infrastructure operators
This system delivers warnings AND all updates within 15-30 seconds of a meteorologist hitting "send"
🇨🇦 Canada: ECCC CAP Alert System - Priority System
Environment and Climate Change Canada uses the CAP (Common Alerting Protocol) system to distribute warnings to:
- Provincial Emergency Management Organizations
- Municipal Emergency Services
- Alert Ready (wireless emergency alerts)
- Media outlets and broadcasters
- Critical infrastructure operators
CAP alerts include real-time updates, cancellations, and geographic polygon data within seconds of issuance
Public APIs - Standard Systems (Both Countries)
These are the public-facing APIs that most weather services use:
- Available to any developer or website
- Data goes through additional processing layers
- Includes formatting for public consumption
- Rate-limited to prevent server overload
- Often missing real-time updates and cancellations
These systems typically have a 2-5 minute delay and may not include all warning modifications
Why Every Second AND Every Update Counts
Tornado warnings provide an average of only 13 minutes of lead time. Getting warnings faster AND staying updated with changes can be the difference between safety and danger.
Speed Advantage
Those extra 2-5 minutes allow people to move from mobile homes to sturdy buildings, get to interior rooms on the lowest floor, or pull over safely if driving.
Update Advantage
Real-time updates mean you know if a storm is moving toward or away from you, if new areas are at risk, or if the threat has been cancelled entirely.
How We Implement This Technology
Direct Priority System Connections
We maintain direct connections to both the NWS Open Interface (US) and ECCC CAP alert system (Canada), the same systems that feed emergency services. This requires special authorization and technical infrastructure to handle both high-priority data streams simultaneously.
Real-Time Processing
When any warning message is issued from either NWS or ECCC - whether new, updated, or cancelled - our systems receive and process the data within seconds. We parse warning details from both US and Canadian formats, track changes, and immediately update our live tracking map and alert systems.
Instant Distribution
All warning data from both countries - new, updated, extended, or cancelled - is immediately displayed to our website visitors through automatic updates, ensuring everyone sees the most current tornado warning information within 30 seconds of either the National Weather Service or Environment Canada issuing any change.
Redundancy and Reliability
While speed is crucial, reliability is equally important. We've built multiple layers of redundancy to ensure you never miss a tornado warning, even if our primary systems experience issues.
Primary Systems: NWS Open Interface & ECCC CAP Alerts
Our main data sources provide warnings AND all updates within 15-30 seconds of issuance from both countries. Both systems are monitored 24/7 and have built-in failover mechanisms.
Backup Systems: NWS Public API & ECCC Public Feeds
If our priority connections experience any issues, we automatically fall back to the standard public APIs for both countries. While this adds 2-5 minutes of delay, it ensures continuous warning coverage without any gaps in service.
Cross-Validation
We continuously cross-reference data from both sources to ensure accuracy and catch any potential discrepancies. This dual-source approach provides both speed and reliability.
