The Netherlands is in for another day of very hot weather, with maximums up to 35 degrees. “It will be downright sunny, but during the evening, the chance of a thunderstorm increases from the south,” Weeronline meteorologist Berend van Straaten said. Tuesday will also be hot, with maximums above 30 degrees, but cooler weather will follow from Wednesday. The KNMI issued a code yellow heat warning, covering the entire country on Monday and Tuesday. The RIVM’s national heat plan is also in effect.
