Karnataka is reeling under the impact of intense pre-monsoon showers, with Bengaluru and several coastal districts witnessing severe rainfall-induced disruptions.
The India Meteorological Department (IMD) has issued a red alert for Karnataka, warning of extremely heavy rainfall on May 26 and 27. With forecasts indicating a prolonged wet spell until May 29, state authorities are on high alert, particularly in flood-prone and low-lying areas of Bengaluru, Mangaluru, and surrounding regions. Bengaluru, India’s technology and innovation capital, is facing the brunt of the weather system. The IMD has predicted generally cloudy skies accompanied by thundershowers and gusty winds ranging between 30 and 40 kmph throughout the week. Maximum daytime temperatures are expected to remain between 25°C and 27°C, while night temperatures will hover around 19°C to 20°C — bringing temporary respite from the summer heat but increasing the risk of urban flooding and transport disruptions.
In several parts of the city, roads were submerged following continuous downpours, especially in residential neighbourhoods with poor drainage systems. Traffic congestion mounted across arterial routes, while residents waded through waist-deep water in low-lying zones. Emergency teams were deployed to pump out water from flooded basements, underpasses, and public spaces. Outside the capital, coastal districts have reported severe damage. In Mangaluru and Ullal, torrential rain flooded homes, farmland, and roadways. In Ullal taluk, villages such as Pavoor Harekal, Ambilimogaru, and Munnur have been particularly impacted, with rising river levels breaching banks and entering homes. Officials confirmed that seven houses were damaged — six in Mangaluru and one in Bantwal. Many local residents have been forced to vacate due to inundation, with temporary shelters being set up by the district administration.
Strong winds accompanying the downpour brought down trees in several regions, including along the Pachchanadi–Moodushedde route, blocking vehicular movement and delaying emergency response. Restoration crews have been working around the clock to clear obstructions, restore power, and respond to citizen distress calls. Local administrations have been asked to remain on high alert and deploy mitigation measures as required. In response to the worsening conditions, district officials have advised families to keep children indoors and avoid flood-affected areas. Safety warnings have been issued, urging the public to stay away from electric poles, snapped wires, and waterlogged zones. Educational institutions in certain coastal and semi-urban areas have been asked to remain flexible with operations depending on rainfall intensity.
The IMD’s early red alert has come as a critical move, allowing municipal agencies and civic bodies to brace for flood-like conditions and initiate preventive action. However, experts warn that unless sustainable and climate-resilient infrastructure is prioritised in cities like Bengaluru, such weather events will continue to strain civic systems. Years of rapid urbanisation, encroachment on natural drains, and underinvestment in eco-sensitive infrastructure have worsened the impact of heavy rain episodes. Environmental analysts emphasise the urgent need to integrate blue-green infrastructure into urban planning — including restored lakes, stormwater drains, permeable surfaces, and decentralised water storage systems — to combat future rain-related disasters. Additionally, the development of equitable housing and resilient road networks in low-income, flood-vulnerable localities has become a policy imperative.
The extreme rainfall comes just days after the monsoon made an early onset in Kerala — the earliest in nearly five decades. Karnataka, Maharashtra, and parts of Kerala are now experiencing above-normal rainfall, disrupting early sowing of Kharif crops, especially in regions where farmlands are now waterlogged. While the showers have brought temporary relief from oppressive heat, they have also laid bare the vulnerabilities of urban centres under changing climate conditions. As rain continues to lash Karnataka, city planners and local governments are being pushed to reconsider traditional drainage and infrastructure norms, leaning towards a climate-adaptive model that ensures safety, equity, and sustainability.
With the IMD maintaining its red alert and forecasting more intense spells through the coming week, Bengaluru and its neighbouring districts are likely to witness ongoing civic and transport challenges. The resilience of urban systems and the preparedness of authorities will be tested over the coming days — offering a litmus test for cities aspiring to become future-ready, climate-resilient urban hubs.
