Tools

nws_find_stations ~379 tokens
Find weather observation stations near a location. Returns stations sorted by proximity with distance and bearing. Use to discover station IDs for nws_get_observations.
nws_get_alert ~360 tokens
Fetch one NWS alert message by ID — a current alert, or an earlier message that an update or cancellation has since superseded and that an active-alert search no longer returns. Takes an id from nws_search_alerts or a references[].identifier from any alert, and returns the same alert fields nws_sear
nws_get_alert_counts ~248 tokens
Count active weather alerts nationwide, per state/territory or marine area, and per marine region, in one small response — the answer to "how many alerts are active, and where" without fetching the alerts themselves. Counts cover every message status, Test and Exercise included, so totalAlerts can r
nws_get_forecast ~501 tokens
Get the weather forecast for a US location. Returns either named 12-hour periods (default) or hourly breakdowns.
nws_get_observation_history ~656 tokens
Get a station's recent observation history, newest first — the trend behind the single latest reading nws_get_observations returns (is pressure falling, is the wind picking up). NWS keeps about the last 7 days per station, and a busy airport station reports as often as every 5 minutes, so a day can
nws_get_observations ~252 tokens
Get current weather observations (actual measured conditions). Accepts coordinates (resolves nearest station automatically) or a station ID directly (e.g., "KSEA").
nws_get_office_discussion ~896 tokens
Get the latest narrative forecast product from a Weather Forecast Office (WFO). The default product is AFD (Area Forecast Discussion), which explains the meteorological reasoning behind the forecast — synoptic setup, model guidance, and forecaster confidence. Other types: HWO (Hazardous Weather Outl
nws_get_zone_forecast ~529 tokens
Get the text forecast for an NWS forecast zone. Returns named forecast periods (e.g., "Today", "Tonight", "Monday") with detailed narrative text — the human-readable, zone-level forecast written by local forecasters. Completes the alert-to-forecast chain: nws_search_alerts returns each affected zone
nws_list_alert_types ~101 tokens
List all valid NWS alert event type names. Use to discover valid values for the event filter in nws_search_alerts, or to browse alert categories. No parameters required.
nws_search_alerts ~1088 tokens
Search active weather alerts (watches, warnings, advisories) across the US. Filter by state, coordinates, zone, land/marine region, event type, severity, urgency, or certainty. area, point, zone, region_type, and region are mutually exclusive — provide at most one.
