The Difference Between Alerts, Hazards, and Preparedness Signals
Published April 26, 2026
HazardNow combines related but different information types. Understanding the distinction helps avoid overreaction or underreaction.
Alerts
Official watches, warnings, and advisories are time-sensitive and should be prioritized.
Hazards
Hazards are conditions or events that can affect safety or operations.
Preparedness signals
Preparedness signals are broader context indicators for readiness and awareness.
How to use the dashboard calmly
- Prioritize official alerts.
- Use hazard layers to understand what is nearby.
- Use preparedness signals for context.
- Do not treat every elevated signal as an emergency.
