buienradarnl

Buienradar.nl is a Dutch online weather service that focuses on rainfall information. The site provides near real-time radar imagery showing precipitation over the Netherlands and parts of neighboring regions, accompanied by short-term rain forecasts. It uses an interactive map with a color-coded overlay that updates every few minutes, enabling users to track where rain is falling and where it is moving. The forecast component, typically covering the next one to three hours, is produced by combining radar extrapolation with model-based predictions to show expected rainfall intensity and timing.

Data sources and processing: Buienradar relies on radar data from national meteorological radar networks, notably KNMI, and supplements this with forecast models and statistical processing to create continuous nowcasts. The service presents results in Dutch and is widely used by residents for daily planning, by outdoor event organizers, and by transportation users to gauge precipitation risk.

Availability and access: Buienradar.nl is accessible via its website and through mobile apps for Android and iOS. It also offers rain alerts or notifications tied to a user’s location, helping users react to incoming showers.

Limitations and accuracy: Rainfall nowcasts are inherently uncertain, particularly for convective rainfall or systems with rapid development; the further ahead in time, the higher the uncertainty. Users should treat the maps as guidance for short-term planning and adjust expectations accordingly.
