Black storm
Black storms, locally called Kali Andhi , Kali Nheri in South Asia (, , , literal meaning: "Black Storm") are violent dust squalls that occur in the late-spring in the northwestern parts of the Indo-Gangetic Plain region of the Indian Subcontinent. They are usually brief, but they can block out the sun, drastically reduce visibility and cause property damage and injuries. They are a common precursor to the arrival of the monsoon in the northern plains. It is quite common in Punjab in the Cholistan and Thar deserts in Pakistan and Rajasthan in India.
