As of 13 March, several rivers were at red level warning stage (highest of five – green, blue, yellow, orange, red) including the Una in the town of Hrvatska Kostajnica near the location of the landslide, where streets and homes have been flooded.

Elsewhere in Croatia, the Korana river in Karlovac was at red level warning stage as of 13 March, standing at 7.81 metres.

Disaster officials said levels of the Sava River were cause for concern, in particular at Jasenovac where levels were at orange warning stage, standing as at 8.54 metres.

Army personnel are working to erect temporary flood defences and help residents to evacuate homes where necessary. Troops have been deployed to flooded areas of Sisak-Moslavina county, including Hrvatska Kostajnica but also Letovanić and Petrinja, where levels of the Kupa river are extremely high. Military personnel have also been deployed to affected areas in Karlovac County.

Croatia Red Cross teams are also operating in areas threatened by flooding, providing assistance to the residents of Hrvatska Kostajnica, Lekenik and Karlovac.

Rainfall is forecast to continue throughout the week and may increase over the weekend 17 to 18 March.
