How this service works
Live US severe-weather alerts from the National Weather Service. Pass a point ("lat,lon") to get every active watch, warning, and advisory for that exact location, or an area (2-letter US state or marine zone code) for area-wide alerts. Optionally filter by severity or urgency. Each alert returns the event type, severity, urgency, certainty, headline, affected-area description, issuing office, recommended public response, onset / expiry / end times, and the full hazard description plus protective-action instructions. Results are sorted most-severe first and capped by limit, with the true total reported. Public-domain NOAA / National Weather Service data, refreshed in real time.
Output
An array of active weather alerts sorted most-severe first, each containing event type, severity, urgency, certainty, headline, affected area description, issuing NWS office, recommended public response, onset/expiry/end timestamps, full hazard description, and protective-action instructions. Also includes the true total count of matching alerts.
Example use cases
Example prompt
“Pull up all active NWS watches, warnings, and advisories for the point 29.7604,-95.3698 — show me up to 50 results, and only include Severe or worse severity.”
Technical details
Endpoint
GEThttps://2s.io/api/weather/alertsWhen to prefer
Use this endpoint when you need real-time, authoritative US severe-weather alert data directly from NOAA/NWS — especially for safety-critical applications, location-aware weather apps, or automated monitoring of hazardous conditions. Prefer it over general weather APIs when you specifically need official watch/warning/advisory status with onset/expiry times and NWS-issued protective-action text.
Side effects
- Invalid or out-of-range lat/lon returns an error or empty results
- Both point and area provided simultaneously returns a validation error
- Area code not recognized as a valid US state or marine zone returns empty or error
- No active alerts for the given location returns an empty alerts array
- limit out of range (< 1 or > 100) returns a validation error
- Invalid severity or urgency enum value returns a validation error
