From 2 November, KNMI will issue yellow, orange and red warnings for smaller areas. This will make the warnings more precise about where dangerous weather is expected.
The new approach replaces warnings that are currently usually issued by province. Meteorologists will soon mark areas on a map that better match the expected weather conditions. As a result, one province may have several separate warning areas, while another part of that province remains outside the warning.
The colour codes themselves will not change. Yellow will continue to indicate a possibility of dangerous weather, orange a high likelihood of dangerous weather with major impacts, and red a weather alarm. The main difference lies in the geographical scale at which KNMI distributes the warning.
According to KNMI, the approach should prevent residents of an entire province being warned when the risk exists only in part of it. The institute expects warnings to become more relevant as a result for people who need to adjust their travel, work or activities.
It is not yet clear whether the Netherlands will consequently receive warnings more or less often. In some weather situations, several small areas may be designated at the same time. The warnings will soon be visible on KNMI's website and app.
The provision of data for professional users will also change. Existing datasets will be replaced by two combined datasets containing warnings up to 48 hours ahead and information on potentially dangerous weather up to a week ahead. KNMI warns that the date of the transition may still change if weather conditions make this necessary.
One story, several perspectives
What is established
- KNMI is moving warnings from provincial to local level.
- The colour codes will remain the same.
- The effect on the number of warnings is not yet known.
Left
Arguments Emphasises that more precise warnings protect people better and that public information should be as closely aligned as possible with the actual risks.
Values Accessibility, public health and the protection of vulnerable groups.
Consequences Fears that people outside small warning areas may underestimate risks if they see general provincial alerts less often.
Centre
Arguments Supports the technical improvement, but wants the criteria and communication to remain clear and consistent.
Values Reliability, predictability and institutional diligence.
Consequences Emphasises clear explanations in the app and media, so that local warnings do not lead to confusion or alert fatigue.
Right
Arguments Values targeted warnings because broad alerts can blur the responsibility of citizens and businesses.
Values Personal responsibility, efficiency and limited government intervention.
Consequences Is particularly concerned about additional operational burdens for businesses and emergency services if small areas change more frequently.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

- confirmed The yellow, orange and red colour codes will remain in place. — The change concerns the geographical scale, not the colour coding. source

Editor's note
The local scale and the planned transition have been confirmed by KNMI and ANP. The effect on the total number of warnings is still unknown and is therefore not predicted.Sources
