New Delhi, June 04: A spell of heavy rainfall and strong winds swept across Delhi-NCR on Thursday, offering much-needed respite from the intense heatwave conditions that have prevailed across the region in recent days.
The sudden change in weather was triggered by a fresh Western Disturbance that became active over northwest India, bringing widespread showers, thunderstorms, and cooler temperatures to the national capital and adjoining areas.
The India Meteorological Department (IMD) has issued a yellow alert for both June 4 and June 5, warning residents of continued rainfall, lightning activity, and gusty winds.
Western Disturbance Brings Rainfall Across Delhi-NCR
Dark clouds covered the skies over Delhi and surrounding regions as rainfall was reported from several parts of the National Capital Region, Haryana, and neighboring areas.
The weather system has brought a swift end to the prolonged spell of extreme heat, with temperatures dropping noticeably after the arrival of rain-bearing clouds.
Meteorologists explained that the current weather activity is being driven by a Western Disturbance, a low-pressure system originating over the Mediterranean region that travels eastward and gathers moisture before reaching northern India.
Wind Speeds Reach Up to 70 kmph
According to the IMD, wind speeds in some areas touched between 50 and 70 kilometres per hour, leading to disruptions in traffic movement and causing trees and branches to sway under strong gusts.
The department had forecast a maximum temperature of around 41°C and a minimum of 30°C for June 4 before the rainfall activity intensified.
The weather agency also warned of thunderstorms, lightning strikes, and gusty winds ranging from 40 to 50 kmph, with stronger gusts possible in isolated locations.
Yellow Alert Continues for June 5
The IMD has maintained a yellow alert for June 5, advising residents to remain cautious amid the possibility of further thunderstorms and rainfall.
Weather officials expect the maximum temperature to remain around 40°C, while the minimum temperature may drop to approximately 26°C due to the cooling impact of the rainfall.
The alert indicates the possibility of localized weather disruptions, including reduced visibility, waterlogging in low-lying areas, and traffic delays.
How Western Disturbances Trigger Thunderstorms
Weather experts explained that as the Western Disturbance approaches the Himalayan region and interacts with the hot, dry air prevailing over northwest India, atmospheric instability increases significantly.
The interaction causes warm, moisture-laden air to rise rapidly into the atmosphere, where it cools and condenses into towering cumulonimbus clouds.
These cloud systems are responsible for producing thunderstorms, lightning, heavy rain, and strong winds across northern India.
Meteorologists noted that such weather systems often intensify during the evening and nighttime hours after the land surface has absorbed heat throughout the day.
Similar Weather Seen in Late May
The latest spell follows a similar round of weather activity during the final week of May, when another Western Disturbance triggered widespread rainfall, thunderstorms, and dust storms across Punjab, Haryana, Delhi-NCR, Uttar Pradesh, and parts of Rajasthan.
According to weather experts, pre-monsoon activity typically becomes more frequent during June and often results in short-duration but intense thunderstorms across northern India.
More Rain Likely Over the Weekend
While no official weather alert has been issued for Saturday, meteorologists believe atmospheric conditions remain favorable for additional rainfall and thunderstorm activity over the coming days.
The ongoing weather pattern is being linked to normal pre-monsoon developments that commonly influence northern India before the arrival of the southwest monsoon.
