New Delhi: Although the southwest monsoon has officially arrived in Delhi, many residents have been left wondering why the city has experienced only scattered showers instead of the widespread rainfall usually associated with the season. Weather experts say the answer lies in the current atmospheric conditions, but relief may be on the way as the India Meteorological Department (IMD) predicts a wetter spell in the coming days.
Monsoon Has Arrived, But Rainfall Has Been Uneven
The IMD declared the onset of the southwest monsoon over Delhi after its advance into the National Capital Region and adjoining states. However, the arrival of the monsoon does not guarantee continuous or heavy rainfall immediately.
Instead, Delhi has mostly experienced isolated light showers and thunderstorms, while many parts of the city have remained largely dry. Weather experts note that this is not unusual during the initial phase of the monsoon.
Why Has Rain Been Limited?
Meteorologists point to several factors behind the subdued rainfall:
- Weak monsoon activity over northwest India in the days immediately following the monsoon’s arrival.
- Lack of a strong low-pressure system over the Bay of Bengal during the early phase, limiting the supply of moisture into north India.
- Localized thunderstorm activity, which has produced rain over some neighbourhoods while leaving others dry.
- Breaks in monsoon circulation, resulting in intermittent rather than widespread showers.
Wetter Days Likely Ahead
The IMD expects rainfall activity to increase over Delhi and surrounding areas during the coming week. The improvement is linked to an active monsoon phase and the development of a well-marked low-pressure area over the northwest Bay of Bengal, which is expected to strengthen moisture flow into northern India.
Residents can expect:
- Light to moderate rain spells.
- Thunderstorms accompanied by lightning.
- Gusty winds during intense showers.
- A gradual drop in daytime temperatures.
- Increased humidity between rain spells.
Temperatures Set to Ease
The limited rainfall has allowed daytime temperatures to remain relatively high despite the monsoon’s arrival. As rainfall becomes more widespread, maximum temperatures are expected to fall by a few degrees, bringing relief from humid conditions.
Yellow Alert in Effect
The IMD has issued a Yellow Alert for Delhi, warning of thunderstorms, lightning, moderate rainfall and gusty winds over the next few days. Residents are advised to remain cautious during periods of heavy showers, especially while commuting, as waterlogging and traffic disruptions are possible.
Outlook for the Week
Weather officials believe the upcoming active phase of the monsoon will help reduce the rainfall deficit recorded during the early part of the season. While rain may still occur in intermittent spells rather than continuously, overall precipitation is expected to increase significantly compared to the past few days.
Conclusion
Delhi’s relatively dry conditions after the official onset of the southwest monsoon are primarily the result of weak monsoon circulation and the absence of strong rain-bearing weather systems. With the IMD forecasting an active monsoon phase and more frequent showers this week, residents can expect improved rainfall, cooler temperatures, and much-needed relief from the recent humid weather.
