A Western Disturbance is a type of extra-tropical cyclonic storm that originates over the Mediterranean Sea.

It travels from west to east, carried by the westerly jet streams, passing through Iran, Afghanistan, and Pakistan before entering northwest India.

These disturbances are typically active during winter and early spring.
-
In India, they bring rainfall and snowfall mainly to Jammu & Kashmir, Himachal Pradesh, Punjab, Haryana, Delhi, and parts of Uttar Pradesh.

Occasionally, their effect extends to northeast India, causing light rainfall there as well.

The rain brought by western disturbances is highly beneficial for Rabi crops, especially wheat.
