How this service works
US National Weather Service active alerts by state or lat/lon - event, severity, urgency, affected areas, expiry and instructions for warnings and watches
Output
Returns a JSON object with a scope descriptor, an array of active NWS alerts (each containing event name, severity, urgency, affected areas/zones, expiry timestamp, and public safety instructions), a data source label, and a count of total active alerts matching the query.
Example use cases
Storm warning check before outdoor event
“Check if there are any active NWS weather warnings or watches in Florida — I need to know about severe thunderstorm or tornado alerts before planning anything outdoors.”
Emergency alert monitoring for travel
“I'm driving through Oklahoma tomorrow — can you pull all current active weather alerts for Oklahoma from the National Weather Service so I know what to expect?”
Hyperlocal alert lookup by coordinates
“What active weather alerts are there right now near latitude 40.7128, longitude -74.0060? I want to see event type, severity, and any safety instructions.”

Endpoint
GEThttps://saylorinnovations.com/api/weather/us-alerts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, official US National Weather Service alert data for a specific state or geographic coordinate. Prefer it for emergency preparedness workflows, travel safety checks, or any automation that needs structured alert metadata (severity, urgency, expiry, affected zones) rather than raw forecast text. It is especially useful when you need to filter or display alerts programmatically.
Side effects
- Invalid or missing state code returns an error
- Lat/lon outside the US may return no alerts or an error
- Limit value outside 1-50 range may be rejected or clamped
- No active alerts returns an empty alerts array with total_active of 0
- NWS upstream outage may cause timeout or empty response
