Monsoon Gains Momentum Across the North
After covering the entire country by July 9, the southwest monsoon has gathered fresh momentum, unleashing an intense spell of rain across large parts of North India. The India Meteorological Department (IMD) has forecast widespread rainfall, thunderstorms,
and strong winds for the weekend. Regions including Delhi-NCR, Haryana, Punjab, Uttar Pradesh, and the Himalayan states of Uttarakhand and Himachal Pradesh are expected to see significant downpours. This wet spell follows a period of highly uneven rainfall, where a strong revival in early July helped narrow a major national rainfall deficit. While the rains bring relief from the heat, they also carry the risk of disruption to daily life.
IMD Issues Alerts for Heavy Rainfall
The IMD has issued alerts for heavy to very heavy rainfall for Saturday, July 11, and Sunday, July 12, across several northern states. An orange alert has been issued for Jammu and Kashmir, while a yellow alert is in place for parts of Uttar Pradesh. Heavy rainfall is also expected over Haryana, Chandigarh, Delhi, Himachal Pradesh, Uttarakhand, and Punjab. These alerts signify the need for preparedness, as the weather system is potent enough to cause significant disruption. The IMD has advised residents in affected areas to remain cautious.
The Science Behind the Showers
This intense rainfall is being driven by a combination of meteorological factors. The monsoon trough, an elongated low-pressure area that is a key driver of monsoon rains, is active across northwest and eastern India. Additionally, a western disturbance over Punjab and associated cyclonic circulations are helping to sustain the widespread rainfall. While these systems are creating active monsoon conditions, their positioning determines where the heaviest rain falls. For now, the focus of the downpour is squarely on the northern plains and the western Himalayan region.
Impact Felt in Hilly and Plain Areas
The effects of the heavy rain are already being felt, particularly in the vulnerable hill states. Uttarakhand and Himachal Pradesh have reported landslides that have blocked numerous roads, including national highways. In Uttarakhand, over 100 roads were blocked, and pilgrims on the Yamunotri route were stranded before being escorted to safety. In Himachal Pradesh, a landslide was reported in Shimla and a bridge collapsed in Sangla. In the plains, the primary concerns are waterlogging in low-lying urban areas and traffic disruptions. The IMD has warned residents to be prepared for these issues and to check travel advisories before heading out.
Weekend Forecast and Beyond
Heavy rain is expected to continue through the weekend, particularly on Sunday, July 12, in states like Uttarakhand, Himachal Pradesh, and parts of Uttar Pradesh. However, some forecasts suggest a slight change in the pattern for Delhi-NCR after the weekend. Rainfall activity might become more subdued from Monday, with a temporary 'monsoon break' expected until around July 15 as the monsoon trough shifts northwards towards the foothills of the Himalayas. This could lead to a rise in temperature and humidity in the capital region before the monsoon potentially picks up again later in the month.
