Czech Republic: Adverse weather forecast in southern and eastern regions July 5
Thunderstorms forecast across southern and eastern Czech Republic July 5. Transport, business, and utility disruptions possible.
Event
Thunderstorms are forecast across southern and western regions of the Czech Republic through July 5. Heavy downpours, strong wind gusts, and possible hail storms will likely accompany the storms. Rainfall totals of around 5 cm (2 inches) are possible across the affected area, with localized heavier amounts of up to 7 cm (3 inches). The Czech Hydrometeorological Institute (CHMI) has issued orange thunderstorm warnings (the middle level on a three-tier scale) across Moravian-Silesian, Olomouc, South Moravian, Vysocina, and Zlin regions and for most of Pardubice Region. Yellow thunderstorm warnings have been issued across South Bohemian Region. Officials could update and possibly extend the coverage of the weather alerts over the coming hours and days.
Hazardous Conditions
Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed or a lack of stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides cannot be discounted in hilly or mountainous areas, especially where the soil has become saturated by heavy rainfall.
Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. The adverse weather conditions could cause power outages throughout the affected area.
Transport
The severe weather could contribute to transport disruptions throughout the region. Traffic and commercial trucking delays might occur along regional highways. Strong winds might pose a hazard to high-profile vehicles. Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.
Severe weather could also trigger flight delays and cancellations at airports in the region. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas that see heavy rainfall and potential track inundation.
Disruptions triggered by inclement weather and resultant hazards, such as flooding, could persist well after conditions have improved - it could take days before any floodwaters recede and/or officials clear debris. If there is severe damage to infrastructure, repair or reconstruction efforts may result in residual disruptions.
Advice
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments prior to travel. Make allowances for localized travel delays, as well as potential supply chain disruptions, where flooding has been forecast. Do not drive on flooded roads. Charge battery-powered devices in the case of prolonged electricity outages.
