What's in it

Dutch weather warnings and potentially dangerous weather from KNMI for the general public. Warnings and potentially dangerous weather are indicated for iciness and snow, rain, fog, thunderstorms, wind(gusts), heat and cold, wind/water spouts. The warnings are issued up to 48 hours in advance; potentially dangerous weather is indicated up to a week in advance. Potentially dangerous weather may become a warning with code yellow, amber or red, but it doesn’t have to.

The data is published in two different formats: CAP (XML) and JSON. All timestamps are in UTC.
