Austria’s civil-protection authorities and national weather service (ZAMG) sounded the highest level of weather alert in the early hours of 5 December after 36 hours of persistent rain and gale-force winds pushed rivers in Carinthia, Styria and Lower Austria to danger level. In Vienna the Danube Canal was put on pre-flood standby, while the city government urged residents and visitors to “avoid unnecessary journeys” until at least Saturday morning.
The meteorological cocktail of warm Atlantic moisture and a cold northern front lowered the snow-line to 700 m in parts of the northern Alps, coating mountain passes and causing fallen trees and minor landslides. By 02:30 the ÖBB closed the mainline section between Bad Hofgastein and Bad Gastein after debris covered the tracks; replacement buses added up to 90 minutes to Salzburg–Carinthia journeys. Drivers faced a patchwork of closures on the S6 Semmering expressway and B 99 Katschberg road, while ASFINAG urged motorists to postpone cross-alpine trips.

Air traffic was also hit. Vienna International reported visibility of just 1 200 m, broken cloud at 300 ft and light rain in its 01:50 METAR, forcing airlines to increase separation times and triggering rolling delays of 30-60 minutes on early-morning departures to Frankfurt, London and Zurich. Airport operator Flughafen Wien said ground-handling crews were working “weather programmes” that slow baggage and de-icing operations; passengers were told to arrive early and keep contact details updated for rebooking messages.
The Interior Ministry confirmed police checkpoints on the flooded B179 Fernpass route near Reutte and the B221 in the Leitha valley to stop heavy vehicles attempting unofficial detours. Cargo operators re-routed time-critical trucks via Slovakia, adding roughly €90 per tractor-trailor in tolls and fuel, according to the Austrian Transport Club. Logistic firms warned that Christmas retail deliveries could slip by 24 hours if the weather system stalls, prompting some multinationals to activate contingency warehouses in Linz and Graz.
For businesses the immediate task is traveller safety and duty-of-care compliance. Mobility managers should monitor ZAMG warnings, use real-time rail and road APIs and advise employees to delay non-essential travel until the all-clear is issued—currently expected late on 6 December. Employers with commuters in affected districts may invoke telework provisions under the new Teleworking Act to keep operations running.
