A national heat plan is in effect across the Netherlands, triggering adjustments and cancellations of numerous sporting events in the coming days. Code Yellow, the first level of the national heat plan, was activated Thursday morning due to rising temperatures. Organizers are modifying schedules and, in some cases, outright cancelling events to protect athletes and spectators from the extreme heat. The affected events span various sports and locations throughout the country. Authorities advise caution and adherence to heat safety guidelines. Further disruptions are anticipated as the heatwave continues. The National Heat Plan aims to mitigate health risks associated with prolonged high temperatures.
