The Czech Hydrometeorological Institute (ČHMÚ) issued an orange-level warning on Sunday, 31 May 2026, for strong thunderstorms, large hail and flash flooding across most of Bohemia and parts of Moravia. Although late-spring storms are common, the agency singled out this system for its combination of super-cell dynamics and very high precipitation rates—up to 30 mm in a single hour—raising the risk of sudden road closures and flight delays.
Prague’s Václav Havel Airport remained open, but airlines pre-emptively padded block times and posted rolling delay notices of 30–90 minutes on key holiday routes to Antalya, Pescara and London.
![Severe Storm Warnings Trigger Travel Disruption Alerts Across Czechia]()
If weather disruptions force you to re-route through a different Schengen state or overstay an existing visa, VisaHQ’s dedicated Czech Republic page (https://www.visahq.com/czech-republic/) can streamline the paperwork. The platform offers up-to-date guidance on Schengen rules, quick document checks and—when necessary—the ability to book urgent consular appointments so travelers can stay compliant even when storms scramble their itineraries.
NOTAMs issued at 14:00 local time instructed crews to expect runway-direction switches and hold-short orders as lightning cells passed within five nautical miles of the airfield. Rail operator České dráhy diverted several inter-city services via secondary corridors to avoid tree-fall zones in Central Bohemia, while regional authorities in South Moravia closed two sections of the D2 motorway after hail left the surface dangerously slick. For corporate mobility and travel-risk teams, the alerts come at the start of the Pentecost school-holiday wave, when expatriate families often drive to Austria or Croatia. Employers should remind staff of the legally-required reflective vests and warning triangles, and consider delaying non-essential road moves until storm cells track eastward on Monday morning. HR departments organising end-of-month onboarding sessions for new foreign hires may want to switch to virtual formats if trains into Prague’s main station face further disruption. The storm system also intersects with the EU’s new Entry/Exit System (EES). Border police confirmed that biometric kiosks at the airport remain operational but warned that power fluctuations could force temporary switch-overs to manual passport stamping—meaning longer queues and inconsistent exit records. Travelers relying on a full 90/180-day Schengen allowance should therefore keep boarding passes and hotel invoices as supplementary proof of exit in case of database outages. Meteorologists expect conditions to ease after midnight, but residual flooding could persist on smaller regional roads. Mobility managers are advised to monitor ČHMÚ updates, airline apps and the Road and Motorway Directorate’s (ŘSD) live-traffic map before dispatching ground transport on Monday. In the longer term, the episode underscores why Czech companies include extreme-weather clauses in assignment letters—an increasingly relevant point as insurers raise premiums for weather-related delays.
