Parts of the Randstad area got more rain on Wednesday than usually falls in the entire month of September. Between 40 and 70 millimeters of rain fell in Zuid-Holland, Noord-Holland and Utrecht on Tuesday, according to Weeronline. Nieuwkoop got a massive 130 mm or rain.
The provinces of Noord-Holland, Zuid-Holland and Utrecht were faced with heavy rainfall on Wednesday. The A20 to Rotterdam had to be closed for several hours due to flooding. Streets in various places were also under water, NU.nl reports.
Public works department Rijkswaterstaat closed the A20 highway at the Kleinpolderplein junction around 11:00 a.m. because the road surface was under water to such an extent that it was unsafe to drive over it. The highway was reopened around 1:15 p.m.
Storms are heading to the southern and central parts of the Netherlands on Tuesday afternoon. Meteorological institute KNMI issued a code yellow weather warning.
The warning is in place for Noord-Holland, Zuid-Holland, Gelderland, Utrecht, Noord-Brabant, and Zeeland from 3:00 p.m. until the evening.
"Chance of thunderstorms with lots of rain in a short time", the KNMI warns. "Traffic and outside activities may be hindered. Avoid open water and open areas, do not shelter under trees. Follow weather reports and warnings."
It's hard to tell with Monday starting out gray and dreary, but the summer is not yet over for the Netherlands. Late summer weather, with temperatures above 20 degrees and maybe even as high as 30 degrees, is heading to the Netherlands from Sunday, Weeronline expects.
Maximum temperatures in De Bilt will not reach 20 degrees on Friday, bringing an end to a record long streak of nationally warm days in the Netherlands, according to Weerplaza.
A national warm day is when maximums reach at least 20 degrees at the national weather station in De Bilt. That has been the case everyday from June 25th till August 23rd - 60 consecutive warm days. The previous record was 53 warm days in 2003.
Maximum temperatures in De Bilt climbed to 20 degrees on Saturday, making it the 100th national warm day in the Netherlands this summer, according to Weerplaza. Weeronline currently expects that the average maximum temperature in De Bilt this summer will come out at 19.1 degrees, which means that this summer is also the hottest summer since historical temperature measurements started in 1706.
The rainfall over the past week was not enough to solve the precipitation deficit in the Netherlands, according to the national water distribution committee LCW. The drought measures will therefore remain in place. The quality of the surface water is also decreasing, NU.nl reports.
There's an increase of botulism and blue-green algae all over the country. The number of fish dying due to the poor water quality is also increasing.
After this year's hot summer, the Netherlands and the rest of the world can expect another four unusually warm years, according to a new statistical analysis of the world temperature by Sybren Drijfhout of the Dutch meteorological institute KNMI and French colleague Florian Sevellec from the University of Brest, the Volkskrant reports.
The warm and dry weather in the Netherlands resulted in fewer Dutch going on summer holiday abroad. In June 8 percent and July 5.5 percent fewer people booked a holiday through a travel agency, compared to the same months last year, sector organization ANVR said, NOS reports.
Flooded streets and traffic problems were the result of heavy rains in the Netherlands on Monday afternoon and night. Oost-Brabant and the Nijmegen-Arnhem region were most affected. Between 20 and 40 millimeters of rain fell in a short period in the east and west of the country, AD reports.
So far this year the Netherlands had 51 summer days - days on which temperatures climbed to 25 degrees or higher in De Bilt, according to Weeronline. 2006 also had 51 summer days, but spread over the entire year.
Sunday was the 51st summer day of 2018. Only one more hot day is needed to break the 2006 record. This may happen on Wednesday or Thursday, when maximums of around 25 degrees are expected. Temperatures also often climb to above 25 degrees in late August and September, according to Weeronline. In 2006 the 51st summer day only happened on September 22nd.
A summer storm that blew across the Netherlands overnight was less severe than the weather services expected. Meteorological institute KNMI withdrew its code orange weather warning for very strong winds just after 11:30 p.m., earlier than expected, RTL Nieuws reports.
Meteorological institute KNMI issued a code orange warning for very strong winds in the western parts of the country. On Thursday night and early on Friday morning gusts between 80 and 110 kilometers per hour are expected.
The code orange warning applies to Zeeland, Zuid-Holland, Noord-Holland, Flevoland, Friesland and the Wadden islands. A code yellow warning applies to the rest of the country, where wind speeds are expected to reach between 75 and 90 kilometers per hour.
A summer storm will hit the Netherlands on Thursday, according to Weeronline. Meteorological institute KNMI issued a code yellow warning for strong winds during the evening.
The hot weather in the Netherlands over the past weeks did not cause an increase in the number of deaths in the country, public health institute RIVM said. According to the institute, this is because many people who were already weakened passed away in the winter, and because the Dutch are getting better at protecting themselves against the heat, AD reports.
Tuesday will still be very hot in the Netherlands, but after Wednesday temperatures will drop to what is normal for August, according to Weerplaza. The weather service expects maximums of between 20 and 25 degrees later this week.
Maximums ranging between 30 and 37 degrees are expected for Tuesday. Cloud cover will increase from the afternoon, and there is a chance of showers or thunderstorms overnight.
There is a good chance of smog in the entire Netherlands on Tuesday, public health institute RIVM warns. Those sensitive to dirty air, for example people with respiratory problems, are advised to stay inside, especially during the afternoon and early evening, RTL Nieuws reports.
"For the entire country, air quality can be bad, but the highest concentrations are expected in the east", the RIVM said. The smog will be at its worst during the afternoon and early evening.
Vegetable giant Greenco is giving away some 6 million cherry tomatoes for free. Due to the hot weather, the tomatoes saw too much sun, causing their skin to become wrinkled. They can therefore no longer be sold because their quality is too low for supermarkets.
There is officially a nationwide water shortage in the Netherlands, but the drinking water is not in danger, according to the Ministry of Infrastructure and Water Management. As the drought is expected to continue in the coming weeks, more measures may be taken to distribute the available water as well as possible, NU.nl reports.
Public health institute RIVM again implemented the National Heat Plan for Limburg, Noord-Brabant, Gelderland, Utrecht, Overijssel and Drenthe. Temperatures in these parts of the country will climb to between 30 and 35 degrees in the coming days, and minimums will not drop much below 20 degrees, according to meteorological institute KNMI.
The RIVM warns people in these provinces to stay hydrated, wear thin clothing that provide protection against the sun, stay in the shade, regularly apply sunscreen, and limit physical exertion during the hottest parts of the day.
Nature lovers who look forward to a purple Posbank each summer, will be disappointed this year, according to naturalist Gerrit Jansen. The heather that turns the hills purple with its blossoms is withered by the persistent drought and will hardly bloom this year, he said to De Gelderlander.
Every year the purple glow over the hills of the Posbank - a national attraction - attracts thousands of visitors in the second half of August. This year they will be disappointed.
Meteorologists expect that the Netherlands may face a second national heatwave by the end of this week. Over the coming week maximum temperatures of above 25 degrees, and sometimes even above 30 degrees, are expected.
For a national heatwave, the weather station at De Bilt must measure maximums of 25 degrees or above for five consecutive days, and three of those days must have maximums of 30 degrees or higher. "It is quite possible that we will reach that again at the end of this week. Then we'll have a second national heatwave", weatherman Maarten Stam said to RTL Nieuws.
This July was the driest ever since rainfall measurements started in the Netherlands. Only 11 millimeters of rain fell nation wide this month, breaking the previous record of 16 millimeters in July 1921, Weeronline reported on Tuesday.
On Tuesday, the last day in July, there is a chance of some rain in the north and west of the country. At most another 1 millimeter of rain will fall. Weeronline therefore feels safe to say the record is broken.
The Netherlands is "blind to drought" according to researcher Henny van Lanen of Wageningen University. The country needs to build up larger reserves of fresh water to prevent drinking water running out during extreme droughts, multiple experts warn, Het Parool reports.
"As a low lying country with large rivers, we are always working on preventing wetness. That explains why we are now so surprised by the drought", Van Lanen said to the newspaper. "Dutch water policy is very conservative: the rest of Europe has been arming itself against drought for much longer."
