  title: WeatherAPI Weather Alerts Check
  summary: Resolve a location, probe its forecast for alerts, then branch to pull full alert detail.
  description: >-
    A government-alert monitoring flow with branching. A free-text query is
    resolved through the search/autocomplete endpoint, a short forecast is
    fetched with the alerts flag enabled to probe whether any warnings exist, and
    the flow branches: when the forecast carries one or more alerts it calls the
    dedicated alerts endpoint to pull full alert detail, and when no alerts are
    present it ends cleanly. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
