Bengaluru: Thundershowers, accompanied by gusty wind travelling at 30-40 kmph, struck many parts of the city on Friday night, inundating roads and causing traffic jams.
The Bengaluru city observatory recorded 21.6 mm of rainfall and HAL airport 6.7 mm until 11.30 pm, the IMD said.
The rainfall occurred in the core areas as well as in eastern and northeastern parts of the city.
While the southwest monsoon has withdrawn from nearly all of North India and some parts of South India, it has remained vigorous over South Interior Karnataka, of which Bengaluru is a part, according to the India Meteorological Department (IMD).
The southwest monsoon, which normally withdraws from Karnataka in early October, has lingered longer this year due to a low-pressure area over west-central Arabian Sea and an upper air cyclonic circulation over the Bay of Bengal.
The IMD sees little or no break between the southwest monsoon and northeast monsoon, which brings Bengaluru rains from October through December.
The met department has forecast moderate rains/thundershowers over Bengaluru Urban and Rural districts on Saturday.
