ČHMÚ warning - Major Heat Related Impact

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.

Check 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.

ČHMÚ warning - Moderate Fire Impact

Risk of fires due to prolonged drought. Possible occurrence of severe fire with subsequent damage. Possible damage to ecosystems, property, forestry, agriculture, etc. Risk of human injury. Deterioration of air quality causing respiratory problems and other health issues.

Do not light fires outdoors, do not burn grass, do not smoke or discard cigarette butts on the ground. Do not use portable stoves or other open flame sources. Follow local bans issued due to drought and fire risk. Stay alert when using agricultural machinery and near railway tracks where sparks from wheels and brakes can ignite vegetation.
