Cloudburst is an extreme form of rainfall, sometimes mixed with hail and thunder, which normally lasts no longer than a few minutes but is capable of creating flood conditions. This leads to flash floods/ landslides, house collapse, dislocation of traffic and human casualties on large scale. Meteorologists say the rain from a cloudburst is usually of the shower type with a fall rate equal to or greater than 100mm (4.94 inches) per hour. During a cloudburst, more than 2cm of rain may fall in a few minutes. When there are instances of cloudbursts, the results can be disastrous . The large water drops are fall down in the form of rainfall creates flashfloods and landslides. Flashfloods are extreme events that are sudden, severe and short lived. It is a sudden and often destructive surge of water down a narrow channel or sloping ground, usually caused by heavy rainfall. In Himachal Pradesh, the flash-floods are mostly the result of cloudbursts. The cloudbursts are the result of combination of different factors like Land use/Land cover, steep gradient, deep valleys and geology of area. The Cloudburst problem is mainly during the months of June to September when the south west monsoon is in progress and snow is melting in the higher reaches. Cloudburst not only causes huge economic loss in the form of damage to houses, industries, public utilities, and property but also many human lives and of cattle heads are lost. The cloudbursts are happened when moisture laden air lifts with sufficient rapidity to form cumulonimbus clouds shedding water load with great strength and ferocity.
