The sudden and intense weather event is almost impossible to forecast and often leads to deadly flash-flooding and landslides

Massive, sudden downpours of rain known as cloudbursts have struck Pakistan and India during this monsoon season, killing hundreds of people in the flash floods and landslides they have triggered.

Cloudbursts are causing chaos in mountainous parts of India and Pakistan, with tremendous amounts of rain falling in a short period of time over a concentrated area

PESHAWAR, Pakistan (Reuters) -Rescue workers on Tuesday recovered more bodies from a mountain village in northwest Pakistan where flash floods triggered by a cloudburst brought down homes and buildings, bringing the death toll there to at least 20, the local district commissioner said.

Across Pakistan, monsoon rains that began in late June have been heavier than usual, killing at least 645 people. Four hundred of those deaths were in the northwest alone, where narrow valleys and river-carved gorges funnel rainwater into sudden torrents.
