Czech Republic: Severe weather forecast across western regions through at least June 2

Adverse weather conditions are forecast across parts of the western Czech Republic through at least June 2. Heavy rainfall in recent days has led to rising river levels in the region and further showers and storms are expected over the coming days. Rainfall totals of up to 8 cm (3.1 inches) are forecast across the region May 31-June 2 and the additional downpours may lead to rivers bursting their banks and resultant flooding in low-lying areas.

As of May 31, the Czech Hydrometeorological Institue (CHMI) has issued the following weather warnings across the affected area:

• Red flood warnings (the highest level on a three-tier scale): Parts of north-central, northwestern, and western Pilsen Region.

• Orange flood warnings: Much of Karlovy Vary and parts of western Central Bohemian and northeastern Pilsen regions.

• Yellow flood warnings: Across much of the rest of the affected area.

• Yellow heavy rainfall warnings: Across much of the affected area.

Officials could update and possibly extend the coverage of the weather alerts over the coming hours and days.

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 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 are possible 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. Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.

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 cancelations are likely in areas that see heavy rainfall and potential track inundation.

Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites.
