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.
