Very strong heat stress expected. Risk of overheating and dehydration. Significantly increased load on the healthcare system and social services (especially care for the elderly and chronically ill). Decline in worker performance and increased risk of occupational accidents, particularly in outdoor work or in stuffy enclosed environments.

Avoid prolonged exposure to the sun or overheated urban areas, strictly maintain hydration with increased intake of non-alcoholic beverages (including mineral replenishment), avoid higher physical/mental loads, ventilate only during cooler parts of the day (usually early morning). Seek medical help in case of health problems. Do not leave children or animals in parked vehicles. Set air conditioning in rooms or vehicles so that the body is not exposed to excessive thermal shock when moving in or out; the difference between indoor and outdoor temperatures should not exceed 5 to 8 °C.

Maximum air temperatures above 37 °C. Complications, especially in transport, livestock production, energy industry, and services. Likely impact on rail transport: rail deformation and fracture. Possible impact on road transport: stranded vehicles, deformation of road surfaces, particularly those exposed to sunlight. Traffic restrictions on some routes, closures, delays. Problems with cooling enclosed halls (livestock production, industry, logistics, etc.). Possible power outages. Essential services partial disruptions.
PřerovCheck the functionality of support systems (especially cooling and ventilation) and backup power sources. Carefully consider travel plans, monitor the traffic situation. Be prepared for possible power outages.CHMI, Tomáš Mejstřík30.07.2026, 13:16
