He said this while he was visiting the Bhadrachalam region Telangana after a week of rain resulted in floods. While talking to reporters, KCR said the cloudbursts are a 'new phenomenon'. "We don't know how true is it that people from other countries are deliberately doing cloudburst in our country," he said, adding that such incidents happened in the past in Kashmir, Ladakh-Leh and Uttarakhand.

What is a cloudburst?
When the amount of rain over a particular region exceeds 100 millimetres per hour, it is called a cloudburst, according to IMD. "Cloudburst occurs when moisture-rich air travels up a mountainous region, forming a vertical column of clouds known as Cumulonimbus clouds. These clouds usually cause rain, thunder and lightning," DownToEarth magazine states. The extreme rain in a short span of time over a geographical region of around 20 to 30 square km has the potential of triggering floods.
The cases of cloudbursts have been increasing over the past few years in the Himalayan region. Recently, cloudburst and subsequent flooding near Baltal base camp en route Amarnath cave in Kashmir claimed over 14 lives and left 44 injured.
