The new week will start with even higher temperatures in Bulgaria. A red code alert for dangerously high temperatures (above 41 degrees Celsius) will be announced in nine districts of Bulgaria on Monday, the National Institute of Meteorology and Hydrology announced. These are Pleven, Veliko Tarnovo, Ruse, Blagoevgrad, Pazardzhik, Plovdiv, Haskovo, Stara Zagora and Yambol. 

In the rest of Bulgaria, an orange code will be in force for high temperatures between 38 and 41 degrees. 

The weather along the Black Sea coast will also be sunny with maximum air temperatures between 31 and 35 degrees and water temperatures at 27 degrees Celsius. 

The heat wave is expected to continue until the middle of the month. The reason for the continuing heat is the transfer of very hot air from North Africa, including Saharan dust.
