Weather warnings issued by governmental institutions in various countries worldwide are gathered into our database and delivered through a single data feed. While every country has their own alerting methods, Vaisala presents all the warnings as unified categories in a harmonized global offering. The feed is an additional module that can be activated for Weather API, Weather File Feed accounts or delivered as GeoJSON files.
When queried with coordinates, the Weather Warnings API returns a sorted list of active warnings for the given location ranked by importance. For each event, the Weather Warnings API provides the generic significance level, generic warning class, and a more detailed event description. The original data from the official sources is also included. The generic codes are meant to ease visualizing the end-user services, while the event descriptions provide more specific textual information.
Governmental severe weather warnings are currently delivered from: Australia, Austria, Belgium, Canada, Denmark, Estonia, Finland, France, Germany, Ireland, Italy, Japan, Latvia, Luxembourg, Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland, United Kingdom and United States. Tailored, forecast-based warnings can be provided globally.
