```

Example prompt: What's the official weather forecast for our construction site at latitude 38.9047, longitude -77.0164? I need to know if there are any active alerts or severe conditions coming up.

## When to prefer this

Choose this endpoint when you need official U.S. National Weather Service forecast data specifically for a construction or outdoor work site identified by GPS coordinates. It is ideal for safety planning, crew scheduling, and alert monitoring where authoritative, government-sourced forecasts are required rather than commercial weather provider estimates. Not suitable for non-US locations.

## Known failure modes

- Coordinates outside the United States return no data or an error (US-only coverage)
- Invalid or missing latitude/longitude values cause a bad request error
- NWS API upstream outage may result in a failed or empty response
- Coastal or offshore coordinates may not resolve to a valid NWS grid point
