Croatia is preparing for a day of intense heat, with most of the country under a red alert warning. The State Hydrometeorological Institute (DHMZ) forecasts daily high temperatures ranging from 34 to 39 degrees Celsius across much of the nation. A very high risk of heatwaves is predicted for nearly all regions. The forecast indicates sunny conditions will prevail alongside the extreme heat. Authorities are advising citizens to take precautions against the heat. This widespread heatwave poses potential health risks, particularly for vulnerable populations.
