Delhi was caught off guard by unexpected rain over the weekend, despite no prior alerts from the India Meteorological Department (IMD). The sudden downpour led to significant traffic disruptions and confusion among residents, especially on Raksha Bandhan, a day known for heavy travel.
IMD’s Forecast Misses the Mark
The India Meteorological Department (IMD) faced criticism as unanticipated rain struck Delhi-NCR, leaving residents unprepared. Despite no rain alert issued until late Friday, heavy showers began late at night, causing significant disruptions on Saturday morning, coinciding with the busy Raksha Bandhan festival.
IMD’s fluctuating alerts added to the confusion, with a red alert downgraded to yellow and then upgraded again within hours. Rainfall measurements indicated substantial precipitation, with some areas recording over 100 mm. Experts attributed the rains to a shift in the monsoon trough and a cyclonic circulation, conditions that typically lead to heavy rainfall in the region.
| Alert Level | Description |
|---|---|
| Red | Severe weather expected |
| Yellow | Weather warning issued |
| Green | No severe weather expected |
Unexpected Rainfall Causes Chaos
Delhi-NCR was caught off guard by unexpected heavy rainfall that began late Friday night and continued into Saturday morning. The India Meteorological Department (IMD) had not issued any rain alerts until the situation escalated, leading to significant disruptions on Raksha Bandhan, a day typically marked by heavy traffic.
The IMD’s fluctuating alerts added to the confusion, cycling through three different warnings within a single day. Despite the agency’s attempts to manage expectations, residents faced traffic snarls and transportation shortages as the rain poured down.
Key Rainfall Details
- Total rainfall recorded: 104.7 mm from Friday night to Saturday evening
- Safdarjung station logged 78.7 mm in 24 hours

Fluctuating Alerts from IMD
The India Meteorological Department (IMD) faced criticism for its inaccurate rain forecasts in Delhi-NCR. Despite no alerts issued until Friday evening, heavy rain began late that night, causing chaos on the roads, especially on Raksha Bandhan. The IMD’s alerts changed rapidly, starting with a red alert in the morning, which was downgraded and then upgraded multiple times throughout the day.
Weather experts attributed the unexpected showers to a southward shift of the monsoon trough and a cyclonic circulation. This led to significant rainfall across the region, improving Delhi’s air quality index to ‘satisfactory.’ With a green alert issued for the upcoming days, isolated rain is still expected, indicating continued weather fluctuations.
| Alert Level | Description |
|---|---|
| Green | Normal weather conditions |
| Yellow | Be aware of potential weather changes |
| Orange | Prepare for adverse weather conditions |
Impact on Raksha Bandhan Celebrations
The unexpected rainfall in Delhi-NCR significantly disrupted Raksha Bandhan celebrations. Residents faced severe traffic congestion and transport shortages, making it challenging for families to gather and celebrate this important festival. The chaotic weather conditions led to a scramble as people attempted to navigate through the city, which is traditionally known for heavy traffic on this day.
Moreover, the Indian Meteorological Department’s fluctuating alerts added to the confusion. The rapid changes from red to yellow and back to orange left many unprepared for the actual downpour, which recorded substantial rainfall across the region.

Rainfall Measurements Across Delhi
Recent rainfall in Delhi has been significant, with the city experiencing unexpected showers that caught many residents off guard. The India Meteorological Department (IMD) failed to provide timely alerts, leading to widespread confusion and traffic disruptions. Between late Friday night and Saturday evening, total rainfall reached 104.7 mm, with various locations recording substantial amounts.
| Location | Rainfall (mm) |
|---|---|
| Safdarjung | 78.7 |
| Pragati Maidan | 100.3 |

Weather experts attribute this rainfall to the southward shift of the monsoon trough and a cyclonic circulation over the region, which typically brings heavy rains. Despite the IMD’s fluctuating alerts, conditions are expected to remain rainy, with isolated showers predicted in the coming days.
Weather Patterns Behind the Rain
The unexpected showers in Delhi-NCR were primarily due to the southward shift of the monsoon trough and a cyclonic circulation over the region. This shift typically results in moderate to heavy rainfall across several northern states, including Delhi, Haryana, and parts of Uttar Pradesh.
Despite the India Meteorological Department’s (IMD) fluctuating alerts, the rainfall was significant, with over 100 mm recorded within 24 hours. Such weather patterns can lead to traffic disruptions and other challenges for residents, especially on busy days like Raksha Bandhan.
Steps to Stay Prepared for Rainy Weather
- Check weather updates regularly from reliable sources.
- Plan travel routes considering potential traffic disruptions.
- Keep an emergency kit ready with essentials.
- Stay indoors during heavy rainfall to ensure safety.
Air Quality Improvement Post-Rain
Following the unexpected rainfall in Delhi-NCR, the air quality index (AQI) showed significant improvement. The AQI dropped to a ‘satisfactory’ level of 81 on Saturday, a welcome change after several days of moderate pollution levels. This improvement can be attributed to the cleansing effect of the rain, which washed away particulate matter and other pollutants.
Weather experts suggest that this trend may continue, with forecasts indicating that the air quality could remain satisfactory in the coming days. The rain not only alleviated immediate air quality concerns but also provided relief to residents during a typically chaotic time.
Steps to Maintain Good Air Quality
- Encourage the use of public transport to reduce vehicular emissions.
- Plant more trees and green spaces in urban areas.
- Promote awareness about reducing waste burning and industrial emissions.

The forecast suggests that light rains and thundershowers may continue over the next few days, with a green alert set for Sunday and beyond.
Weather experts indicate that the monsoon trough’s southward shift has contributed to the recent rainfall, and this pattern may persist.
