US Weather Alerts API
Live United States weather alerts as an API, straight from the National Weather Service. Get every active severe-weather warning, watch and advisory — tornado warnings, flash-flood and river-flood warnings, severe thunderstorm, winter storm, blizzard, excessive-heat, hurricane, red-flag and dozens more — filtered by US state, by a latitude/longitude point, or by NWS forecast/county zone, and refine by severity (Extreme, Severe, Moderate, Minor), urgency or event type. Each alert carries the event name, severity, urgency and certainty, the headline, the affected areas, the full description and the official protective-action instructions, plus the effective, onset, expires and ends times. See how many alerts are active nationwide and broken down by state, resolve any location to its NWS office, forecast zone and county, browse the full list of alert event types, and look up terms in the NWS weather glossary. Perfect for weather dashboards and safety apps, emergency-notification systems, smart-home automations, Discord/Slack bots and travel tools. No accounts, no upstream key. Covers the United States; for forecasts use the Weather API.
