“Heat waves and showers in the metropolitan area may be repeated next summer,” RIA Novosti quoted Kisilev as saying.

According to him, "on average, according to statistics, this phenomenon is becoming more frequent."

“Rather, heat waves will be more frequent, but to say how often I would beware. The same goes for showers, ”he said.
