On NUjij, the NU.nl discussion platform, critical questions are regularly asked about KNMI weather warnings. 'I do not believe it. How often are they wrong? ', They also responded on Friday. We submit the most frequently asked questions to KNMI.
- Code yellow : possible risk of dangerous weather, be alert
- Code orange : high risk of dangerous weather, be prepared
- Code red : weather alarm for extreme weather with a lot of impact
Do you not give up the codes unnecessarily? Soon people will no longer take measures.
"No, we don't do that. We give the codes very carefully. We are reducing social damage and the problems of extreme weather. Today, too, there is a lot of nuisance locally: roads are flooded and water flows into some buildings."
I have the idea that codes are being issued more often. Is this correct?
"The number of times we issue the codes does not increase compared to other years. What we do see is that code yellow receives more attention in the media. That is fine, but sometimes people get the wrong impression. For example, when we code If the yellow light for a thunderstorm occurs, the media sometimes write 'KNMI issues the weather alert'. This makes the yellow code, our lightest warning, heavier than what it was intended for (only code red is a weather alarm, red). "
Why does code yellow still exist? Code orange or red can still be understood because the chance is high, code yellow seems negligible to me.
"Code yellow, unlike the other codes, is more targeted. If you're working inside all day, you might notice less. But during an evening, for example, it's good if the organizers are warned of thunderstorms. You may have to take the weather less into account than others. Social parties such as Rijkswaterstaat, Schiphol, ProRail, police and fire brigade also need to carefully anticipate extreme weather. "
90What do the different weather codes mean?
Is a province not too large an area for weather codes?
"It is our job for the government to do this per province. We are constantly trying to better understand the weather codes per province, for example through weather maps on social media and the texts on our website. We are talking about 'the west' of the province , not just the entire area. "
Isn't it time for a new system?
"We are thinking about a system on a smaller scale, but there are a lot of questions involved. How should we classify those smaller areas? What do our stakeholders think? And is the Netherlands suitable for a smaller scale at all?"
For whom are weather codes intended? Only for citizens, or also for organizations?
"For both. The codes are a guide to the citizen. Take advantage of it yourself. Make your own assessments. A doctor will still visit his patients at Oranje. Another will postpone something for a day. In addition, several organizations where code orange different protocols are put into operation. For example, the fire brigade, the police and the security regions are more alert. The codes therefore apply to both the general public and organizations. "
What do you think about the criticism of weather codes?
"We take criticism seriously, but the codes remain an expectation. We try to communicate this better to the people. It sometimes happens that thunderstorms, for example, do not develop further or disappear above the North Sea. But, we give the codes of course not just finished. If we do it, then there is a real chance. People are also inclined to remember 'misses' for a long time, but the many times that the warnings have been 'off the mark', we take for granted. "
