Denmark: Adverse weather forecast across most of the country through at least Oct. 3

Adverse weather forecast across Denmark through Oct. 3. Flooding and disruptions possible.

Warning

Event

Heavy rainfall, severe thunderstorms, strong winds, and possible flooding are forecast across most of Denmark through at least Oct. 3. A low-pressure system is forecast to track north-eastward over Jutland in the coming hours.

As of early Oct. 3, the Danish Meteorological Institute has issued orange (middle level on a three-tier scale) heavy rain warnings across Central Denmark and North Jutland regions; 2-4 cm (0.8-1.6 inches) of rain is forecast. Yellow heavy rain warnings are in place across the rest of Denmark. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming 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 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 are possible in hilly or mountainous areas, especially where heavy rain has saturated the soil.

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.

Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas with heavy rainfall and potential track inundation. Severe weather could also trigger flight delays and cancellations at regional airports.

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 employees' inability to reach work sites. Electricity and telecommunications service disruptions are possible where significant flooding, strong winds, or landslides impact utility networks.

Advice

Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and 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.
