All of northern India is experiencing heavy rain, with regional weather agencies issuing warnings of more rain.
The heavy rain in the region, including Delhi, is caused by the interaction of a western disturbance and monsoon winds, according to the India Meteorological Department (IMD).
The IMD has issued a red signal for Uttarakhand, warning that the mountainous state will face heavy rain. A video purporting to depict shelf clouds near Haridwar in Uttarakhand recently surfaced on social media.

The video showing the terrifying sight of clouds is gaining popularity on social media. When there is heavy rain in a place, these kinds of movies are frequently posted on social media, citing the unusual occurrence. However, there is no way to verify the videos. NDTV cannot confirm the legitimacy of the video.
It appears to have been first posted on July 9 by a user named Anindya Singh, who claimed that a friend shared the tape with him.
The impressive cloud formation, on the other hand, has piqued the interest of social media users who want to learn more about the unusual cloud formation.

What exactly are platform clouds?

Shelf clouds, also known as Arcus clouds, are frequently connected to violent storm systems, according to the US government’s National Weather Service (NWS), and are often reported as wall clouds, funnel clouds, or rotation.
These clouds can occasionally be observed below cumulonimbus clouds, which are dense, towering vertical clouds that bring heavy rain.
Shelf clouds can appear quite dramatic, with a characteristic dark or threatening appearance due to the contrast between the cloud base and the surrounding sky. They are frequently associated with severe weather events, such as thunderstorms, and can be accompanied by high winds, heavy rain, and, on rare occasions, hail.
While shelf clouds may seem frightening, they are not generally associated with tornadoes or other rotating phenomena, although they may be present in storm systems that produce such weather events.
What causes shelf cloud formation?
Shelf clouds swept the skies in #Uttarakhand on Monday night, casting an eerie calm before the storm. These clouds serve as a reminder of the bad weather that is developing in the region. The ongoing monsoon mayhem has already claimed at least 9 lives in the state so far… pic.twitter.com/BdZXryH3WJ

Specific weather conditions cause shelf clouds to form. When a cold downdraft from a cumulonimbus cloud hits the ground, it quickly flows across the surface. This action pushes the already warm and humid air upwards.
Water vapor condenses as warm air rises, creating characteristic patterns associated with shelf clouds. When there are multiple wind directions above and below the newly formed cloud, the newly formed cloud may roll. During some weather events, this mix of elements contributes to the production of shelf clouds.
