  title: Tomorrow.io Location Severe Weather Events
  summary: Save a location, scan it for severe weather events, and branch on whether any are active.
  description: >-
    A situational-awareness flow for a point of interest. The workflow creates a
    saved location, then queries the Events API for high-impact weather
    phenomena (severe weather, fires, floods, lightning) within a buffer around
    that location, and branches on whether any events were returned so callers
    can route to escalation or all-clear handling. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
