IMD Defines Cloudburst as Extreme Rainfall Event
IN · Published Sep 7, 2026
The India Meteorological Department (IMD) has defined a cloudburst as an extreme rainfall event where 100 millimetres or more of rain is recorded within a short period, typically an hour, over a small geographical area.
Such events are often associated with intense thunderstorms and can lead to sudden and severe flooding.

Impact & Risks

Cloudbursts can lead to flash floods, landslides, and significant damage to infrastructure, particularly in hilly and mountainous regions. The sudden and intense nature of these events often leaves little time for evacuation or preparation, increasing the risk to human life and property. Vulnerable areas, such as those with poor drainage systems or unstable slopes, are particularly at risk. The aftermath of a cloudburst can also disrupt transportation, communication, and access to essential services.
