Croatia to get more precise weather warnings from 22 September

(DHMZ)

Croatia is changing the way potentially dangerous weather is communicated to the public, with a new warning system coming into effect on 22 September 2026.

The Croatian Meteorological and Hydrological Service (DHMZ) will begin issuing warnings for dangerous weather phenomena by county across mainland Croatia.

The current system divides the country into eight larger climatic regions. Under the new system, warnings will be issued for 20 counties and the City of Zagreb, providing a more geographically detailed picture of potential weather risks.

DHMZ says the new system will make it easier for people to see whether a warning applies specifically to the area where they live, work or are travelling.

A new and more detailed warning map will also be introduced on the DHMZ website.

The warning timeline will provide additional information, allowing users to see which warnings have already passed, which are currently active and which are expected later in the day.

The colour system will remain unchanged.

Green indicates that there is no warning, while yellow represents potentially dangerous weather. Orange indicates dangerous conditions and red represents extremely dangerous weather.

The types of weather covered by warnings will also remain the same for mainland Croatia. These include wind, rain, fog, snow and ice, thunderstorms, exceptionally high temperatures and exceptionally low temperatures.

The change is particularly relevant to Croatia because of the country’s varied geography. Weather conditions can differ considerably between coastal, mountainous and continental areas, while individual counties can also cover large and geographically diverse areas.

A more localised warning system is therefore intended to provide users with a clearer indication of where hazardous conditions are expected.

The change comes after another summer in which Croatia experienced a range of extreme weather conditions, including intense rainfall, storms and wildfires.

For tourists, motorists, outdoor workers and residents, the new system will provide a more detailed way of checking local weather risks.

DHMZ’s updated system will be introduced nationwide from 22 September.
