Heavy rain alert in North India: New western disturbance will bring thunderstorms, hailstorms and snowfall

KKN Gurugram Desk | A fresh spell of moderate to heavy rainfall is expected to sweep across North India starting April 16, 2025, as a new Western Disturbance becomes active over the Western Himalayan region. The India Meteorological Department (IMD) has issued alerts for several states, forecasting rain, thunderstorms, gusty winds, and even snowfall in some areas.

According to weather experts, including a recent Skymet Weather report, this disturbance could lead to significant weather activity between April 16 and April 20, particularly affecting Jammu & Kashmir, Himachal Pradesh, Uttarakhand, and parts of Ladakh.

Western Disturbance to Impact Weather Across the Himalayas

What is a Western Disturbance?

Western Disturbances are extra-tropical storms originating in the Mediterranean region that move towards India, especially during winter and spring months. These systems are known for bringing unseasonal rain, snow, and temperature drops to northern India.

Active System from April 16

The upcoming Western Disturbance, expected to begin influencing the region from April 16, will likely have widespread effects over the Western Himalayan states. Experts believe this system is stronger than the previous one that recently impacted northern India.

Potential Hazards and Travel Advisory

Due to the intensity of the system, the IMD and local administrations have issued the following warnings and recommendations:

• Avoid travel in hilly terrains between April 18–20 unless absolutely necessary.

• Possibility of landslides, road blockages, and flash floods in vulnerable regions.

• Farmers are advised to delay harvesting and cover ripened crops where possible.

• Tourists should check weather advisories before visiting hill stations or high-altitude passes.

Why This Weather System Matters

Unseasonal Rains Disrupt Normalcy

This is the second major Western Disturbance this month, which has raised concerns about unseasonal rain damaging standing crops, particularly wheat and fruits in North India. These disturbances, though natural, have begun to appear more frequently due to climate pattern shifts.

Impact on Agriculture

• Wheat, barley, and fruit orchards in Punjab, Haryana, Himachal Pradesh, and Uttarakhand are vulnerable.

• Storms or hail could damage crops nearing harvest, affecting both yield and quality.

Climatic Trends and Changing Weather Patterns

Weather experts suggest the increasing frequency of Western Disturbances and erratic rainfall patterns are tied to global climate change. Warmer ocean temperatures, jet stream fluctuations, and El Niño/La Niña phenomena can all contribute to these shifts.

Need for Better Preparedness

• Investment in early warning systems and disaster preparedness at the local level is essential.

• Stronger communication between IMD, state agencies, and the public can minimize damage and loss of life.

The upcoming Western Disturbance from April 16 to April 20 is expected to bring significant weather activity to the northern parts of India. Residents in Jammu & Kashmir, Himachal Pradesh, and Uttarakhand should stay alert and follow all official advisories.
