# Overnight rain cools Bengaluru, KIA records 94.2 mm 2026-09-20T21:23:17+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet Bengaluru woke up to a rainy Sunday morning after widespread overnight rainfall, bringing relief from weeks of hot and humid weather. The Kempegowda International Airport (KIA) weather station recorded 94.2 mm of rain in the 24 hours ending 8:30 am, while the HAL Airport station logged 66 mm and Bengaluru city recorded 15.9 mm, according to the India Meteorological Department (IMD). The maximum temperature at the city station dropped to 28.3°C on Sunday from 31.2°C the previous day. The heavy downpour at KIA caused one international flight to be diverted to Chennai and one domestic flight delayed by 30 minutes. Airport officials said the rest of the operations continued as usual. The IMD said a low-pressure area over the North Andaman Sea is expected to intensify into a depression over the East-Central Bay of Bengal on September 21 and a deep depression the next day, moving towards the South Odisha-North Andhra Pradesh coast by September 23. IMD has issued a yellow alert for several districts across Karnataka, including Bengaluru, predicting widespread rainfall until September 24. The forecast for Bengaluru says cloudy skies with light to moderate rain and gusty winds of 30-40 kmph are likely, with temperatures around 32°C maximum and 20°C minimum. ## Indian Opinion Analysis The yellow alert covers both south and north interior Karnataka, including districts like Bidar and Kalburgi that are typically drier, suggesting a widespread weather system. The IMD's track for the developing depression points to landfall near the Odisha-Andhra coast, which often triggers heavy rain in Karnataka's interior districts due to the monsoon trough. For Bengaluru, the key question is whether the rain will ease the water shortage that has persisted despite earlier monsoon spells. Residents and civic agencies will watch the next 48 hours closely as the system intensifies, with the September 24 yellow alert end date marking the likely window for the heaviest downpour. ## Coverage - thehindu.com Tags: Bengaluru, India Meteorological Department, Karnataka, Kempegowda International Airport Canonical: https://indianopinion.org/overnight-rain-cools-bengaluru-kia-records-94-2-mm/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
