The National Meteorology Administration issued a yellow code warning indicated prolonged heat and heat discomfort for 22 counties across Romania on Tuesday.

It warned that a heat wave would affect the Romanian provinces of Crisana and Banat in western Romania, Oltenia and Muntenia in the south, as well as the southern part of Moldova (east) and locally in Dobrogea (south east) between Thursday June 21 and Sunday June 24.

Temperatures in the regions are expected to rise as high as 38 degrees Celsius during the period.

The temperature-humidity index will stay somewhere around the critical threshold of 80 in most of Romania, northern parts excepted.

And heat discomfort will settle throughout the week as night time temperatures are not expected to go below 20 degrees Celsius.

The heat wave may persist during the first part of next week as well, the warning says.
