The Czech Republic is bracing for another intense heatwave following a brief weekend cool-down. Hot air originating from Africa will push temperatures close to 40°C (104°F) during the day, accompanied by tropical nights. Sunny conditions will prevail initially, but clouds will increase starting Wednesday. This incoming cloud cover signals the end of the heatwave, as showers and thunderstorms are expected to develop. The approaching cold front will bring a much-needed relief from the extreme temperatures. These storms offer a respite, but also necessitate preparedness for potential disruptions. Authorities advise residents to stay hydrated and take precautions against the heat.
