Weather Warnings

Data feed of the governmental severe weather warnings

The Foreca WarningFeed integrates weather warnings from many national warning systems worldwide and presents them in a harmonized global offering. The feed is an additional module that can be activated for Foreca Weather APIWeather File Feed accounts or delivered as GeoJSON files.

Data Delivery

When queried with coordinates, Foreca Warning feed returns a sorted list of active warnings for the given location by importance. For each event, the WarningFeed 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 developed by Foreca are meant to ease visualising the end-user services, while the event descriptions provide more specific textual information.
