Monsoon in Delhi: IMD Issues Yellow Alert as Rain Expected to Arrive Tuesday

Monsoon in Delhi: IMD Issues Yellow Alert as Rain, Thunderstorms Expected

The eagerly anticipated monsoon in Delhi is expected to arrive earlier than usual this year, according to the India Meteorological Department (IMD). The national capital has been placed under a yellow alert, with forecasts predicting rain, thunderstorms, and gusty winds over the next few days. This development brings both relief from the prevailing heat and concerns over potential flooding.

Early Arrival of Monsoon in Delhi

Typically, the monsoon in Delhi begins around June 30. However, this year, the IMD has projected the monsoon will reach the city by June 24, 2025. This early onset is being attributed to favorable weather conditions, which are also likely to push the monsoon into other northern states like Rajasthan, Punjab, Haryana, and Chandigarh.

The IMD noted that Delhi has already seen three rainy days this month, with precipitation exceeding 2.4 mm. While this brings hope for more comfortable temperatures and improved air quality, it also heightens the risk of waterlogging and flash floods.

Delhi’s Flood-Prone Geography and Drainage Challenges

Delhi’s vulnerability to flooding during the monsoon is well documented. Located along the Yamuna River, the city has experienced several major floods since 1900, notably in 1924, 1947, 1976, 1978, 1988, and 1995.

Much of the flooding can be attributed to the overflow of the Yamuna when large volumes of water are released from upstream dams like Tajewala. In addition to riverine flooding, climate-induced heavy rainfall events—like the one in June 2024—can cause severe urban flooding, particularly in low-lying areas.

Delhi is divided into five major drainage basins based on topography: Najafgarh, Alipur, Shahdara, Kushak-Barrapullah, and Mehrauli. These basins channel rainwater into the Yamuna River. However, drainage efficiency has been hampered by encroachment and the dumping of solid waste, reducing the carrying capacity of the drains.

With the monsoon in Delhi approaching, authorities are actively clearing clogged drains, particularly in flood-prone areas such as Karkari More in East Delhi.

Weather Forecast and Precautionary Measures

The IMD’s yellow alert suggests residents should prepare for light to moderate rain, thunderstorms, and wind speeds of 30-40 kmph. Monday’s weather report indicated a minimum temperature of 28.4 degrees Celsius and 74% humidity. The maximum temperature is expected to hover around 36 degrees Celsius.

The rainfall is likely to offer some relief from muggy conditions and bring down pollution levels. As of 9 a.m. on Monday, Delhi’s Air Quality Index (AQI) stood at 96, falling within the ‘satisfactory’ category, according to the Central Pollution Control Board.

Authorities have urged citizens to remain alert, especially while engaging in outdoor activities. Visibility may be affected, and waterlogging in low-lying regions could disrupt traffic and daily routines.

Urban Planning and Climate Preparedness

The monsoon in Delhi also highlights the urgent need for better urban planning and flood management strategies. According to a report by The Energy and Resources Institute (TERI), encroachment and poor solid waste management continue to choke the city’s drainage systems.

Urban planners suggest a multifaceted approach, including:

• Regular desilting of stormwater drains
• Implementation of rainwater harvesting systems
• Upgrading drainage infrastructure
• Public awareness campaigns on waste disposal

Given Delhi’s growing population and urban sprawl, enhancing the city’s resilience to monsoon-related disasters is more important than ever.

Preparing for Monsoon in Delhi: What Residents Should Do

With the monsoon in Delhi set to begin soon, residents are advised to take a few precautionary steps:

1. Avoid Waterlogged Areas: Stay away from areas known for flooding, particularly during peak rainfall hours.
2. Stay Updated: Follow IMD updates and heed any warnings or alerts.
3. Secure Electrical Appliances: Unplug electronics and ensure they are not in areas prone to flooding.
4. Keep Essentials Ready: Stock up on batteries, drinking water, non-perishable food, and first-aid supplies.
5. Drive Carefully: Roads may become slippery; avoid driving unless necessary.

Conclusion

The arrival of the monsoon in Delhi is both a welcome respite and a potential risk. While the rains promise to bring cooler temperatures and a cleaner atmosphere, they also underscore the city’s chronic issues with flooding and infrastructure.

As the monsoon sets in early this year, residents and authorities alike must remain vigilant and prepared. Ensuring proper drainage, avoiding flood-prone areas, and staying informed are key to navigating the season safely. With collaborative efforts and community awareness, Delhi can better manage the seasonal challenges brought on by the monsoon.
