Six regions in eastern and southeastern Bulgaria are under a yellow warning for strong wind. The National Institute of Meteorology and Hydrology (NIMH) issued the warning for Dobrich, Varna, Burgas, Yambol, Haskovo and Kardzhali.
The institute is telling people to watch out for objects the wind could blow away, and says outdoor activities in these areas may be disrupted.
Along the southern Black Sea coast, forecasters expect a moderate to strong northeast wind, cloudy skies and rain in places, with highs of 20 to 21 degrees. Sea temperatures will run from 20 to 22 degrees, with waves of 3 to 4 on the scale.
