Germany: Adverse weather forecast across southwestern and far southern regions through at least Nov. 18
Severe weather forecast across parts of southwestern and far southern Germany through at least Nov. 18. Flooding and disruptions possible.
Event
Heavy rainfall and strong winds are forecast across parts of southwestern and far southern Germany through at least Nov. 18. Continuous heavy rainfall is expected in parts of the Black Forest in western and southwestern Baden-Wurttemberg State and the Allagau mountains in southeastern Baden-Wurttemberg and far southwestern Bavaria states Nov. 17-18. Rainfall amounts of 3-5 cm (1.2-2 inches) are possible across parts of the affected area. Strong winds gusting up to 95 kph (59 mph) are also forecast across much of the affected area Nov. 17-18.
As of Nov. 17, the German Weather Service (DWD) has issued orange warnings for continuous heavy rain (the second lowest level on a four-tier scale) across the affected area. Orange and yellow strong wind warnings are also in effect for much of the affected area. Officials could update and possibly extend the coverage of 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 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 wind damage impacts utility networks.
Transport
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 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.
Advice
Monitor local media for updated emergency and weather information. Seek updated information on weather and road conditions before driving or routing shipments through areas where severe weather is forecast. Plan accordingly for potential delivery delays if routing shipments by truck through the affected area. Do not attempt to drive through flooded areas. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
