From Source to Product Signal

Test a Product Idea in Four Steps

Met Éireann exposes current warnings as JSON with CAP IDs, regions, and issue/onset/expiry times. Start with five records. Its reuse terms require attribution and preserving warning meaning; remove expired warnings and do not treat an empty list as a general safety statement.

Check the Setup

  • Python 3.10 or newer
  • An internet connection
  • The requests Python package
2

Access the Data

  1. 1.Read Met Éireann's open-data and weather-warning reuse conditions.
  2. 2.Fetch the national JSON warning list once.
  3. 3.Retain region IDs and full validity intervals when displaying warnings.
