Bengaluru: After several days of warm and humid weather conditions, the city is likely to witness intense evening thunderstorms accompanied by heavy rain, gusty winds and isolated hailstorms across certain areas. Weather observers have warned that changing atmospheric conditions could lead to short periods of severe weather activity, potentially causing disruptions in several parts of the city.
Authorities and weather experts have advised residents to remain cautious during evening travel as sudden weather changes may affect normal movement and traffic conditions.
Heavy rainfall expected during evening hours
According to weather observers, atmospheric conditions have become highly favourable for moderate to heavy rainfall and thunderstorm activity.
Forecasts indicate that significant rainfall activity is likely between 5.30 pm and 9.30 pm, with thunderstorms expected to develop over various parts of Bengaluru and nearby areas.
Experts said gusty winds accompanying the storms could affect several neighbourhoods and may result in temporary disruptions.
Strong winds during thunderstorms can occasionally lead to fallen branches and uprooted trees, affecting traffic flow and public movement.
Waterlogging concerns remain in vulnerable areas
Forecasters have warned that sudden high-intensity rainfall could result in water accumulation in low-lying areas of the city.
Areas with existing drainage challenges may be particularly vulnerable if intense rainfall occurs over short periods.
Recent rainfall episodes in Bengaluru have already highlighted drainage issues in some locations, where even short-duration heavy showers resulted in flooding of roads and traffic congestion.
Officials have advised commuters and residents to remain alert while travelling, especially during evening peak hours when weather conditions are expected to deteriorate.
Pre-monsoon weather pattern driving storms
Experts said the expected weather activity is linked to a larger pre-monsoon pattern currently affecting southern India.
During the pre-monsoon period, intense daytime heating combines with moisture-laden winds, creating unstable atmospheric conditions favourable for thunderstorm development.
These conditions often lead to sudden evening showers and thunderstorms that may vary in intensity across locations.
Bengaluru has witnessed several rounds of rain and thunderstorm activity in recent days, bringing temporary relief from increasing temperatures.
However, the changing weather has also exposed vulnerabilities in urban infrastructure, particularly drainage systems and traffic management during heavy rain events.
Hailstorms possible in isolated areas
Weather experts stated that the current atmospheric setup could make the weather system stronger than previous episodes.
They indicated that a combination of moisture, wind movement and atmospheric instability over the region may contribute to more intense weather activity.
Apart from heavy rainfall and thunder, isolated hailstorms are also possible in some parts of Bengaluru and surrounding districts.
The rainfall is expected to reduce temperatures after sunset and provide relief from recent humid conditions.
However, experts cautioned that weather intensity may increase briefly in isolated pockets, making it important for residents to remain attentive to changing conditions.
With dark clouds gathering over parts of the city, Bengaluru may witness another evening marked by thunder, lightning and heavy rainfall.
