It will become increasingly warmer in the coming days and that is why code yellow applies to the entire country on Thursday and Friday, except for the Wadden. The KNMI says there is a chance of persistently warm weather, with high humidity and higher night temperatures. The National Heat Plan will also be in force throughout the country from 10 a.m. on Thursday.
It is expected to be the warmest on Friday, with local temperatures rising to 35 degrees. There is therefore a chance of thunder. It will also be warm on Thursday. Then the maximum temperatures are between 27 and 32 degrees. During the weekend it will remain very warm, especially in the southeast, and on Monday the mercury will probably rise again to above 30 degrees throughout the country.
The National Institute for Public Health and the Environment (RIVM) announced the heat plan on Wednesday after consultation with the KNMI. The heat plan makes informal caregivers and healthcare workers extra alert to caring for vulnerable people, such as the elderly and small children. The RIVM advises them to ensure there is sufficient drinking water nearby, to advise people to go outside early in the morning or late in the evening and to keep the house cool.
People over 75 are a particularly vulnerable group. They have difficulty controlling their body temperature and are less likely to feel thirsty. People with a chronic condition, people living on the street and young children are also vulnerable.
The National Heat Plan comes into effect if the KNMI expects 27 degrees or more for four days in a row. According to the health institute, the heat can cause people to suffer from fatigue, headaches and concentration problems. More serious health problems, such as dehydration or heat stroke, are also at risk.
The last time the Heat Plan was in effect was mid-August last year.
