 a cloud burst occurs in monsoon clouds when they move towards the  northern direction i.e towards the higher altitudes, as the heavy clouds become heavier due to the accumulated water they experience a sudden imbalances and it results in the cloud burst and heavy rain fall in the form of hail. The rate of rain fall in this case can go upto 75mm per minute

cloudburst  is an extreme amount of precipitation, sometimes with  hail  and  thunder , which normally lasts no longer than a few minutes but is capable of creating flood conditions. Colloquially, the term cloudburst may be used to describe any sudden heavy, brief, and usually unforecast rainfall.Meteorologists say the rain fall rate equal to or greater than 100 mm (3.94 inches) per hour is a cloudburst.The associated convective cloud, can extend up to a height of 15 km above the ground.

During a cloudburst, more than 20 mm of rain may fall in a few minutes. When there are instances of cloudbursts, the results can be disastrous. Cloudburst also responsible for Flash flood creation.
Rapid precipitation from cumulonimbus clouds is possible due to so called Langmuir precipitation process in which large droplets can grow rapidly by coagulating with smaller droplets which fall down slowly.
