No, HAARP is not the cause of the floods in the Karlovo region (Bulgaria)
The claim that the U.S. Army-led HAARP program was the cause of the heavy rains that flooded several towns the Karlovo region is not true. Russian officials have not warned of the activation of HAARP, nor has the Bulgarian caretaker Prime Minister admitted to its use. The U.S. HAARP research program did exist until 2014, but it did not engage in weather control.
