The Rába faced record water at 4.22m at Szentgotthárd, initiating a third-degree flood alert and prompting the National Water Management Directorate (OVF) to mobilize over 400 staff members to build up extensive flood defense efforts, including placing 120,000 sandbags to construct a 2.5 km flood barrier in Körmend. The Strém and Pinka rivers nearly received the monthly rainfall average in six hours, the latter recording its highest water level ever at 5.08m in Felsőcsatár.
