A heatwave entered Balkan countries from the west early this week and the next few days are expected to be the hottest so far this year.

In Romania, the authorities issued a warning that the country was entering a so-called "yellow" phase of heat alert, meaning temperatures above 30 degrees celsius and high levels of ultra-violet radiation.

Code Yellow has been issued throughout Bulgaria due to the high temperatures expected to range between 33 C and 38 C, Thursday.

The thermometers in Sofia will show 34 C, the National Institute for Meteorology and Hydrology reports.

Weather in the mountains will be sunny and warm with maximum temperatures of 27 C at 1200 m, and at 2000 – about 21 C.
