The India Meteorological Department is developing a flood warning system for Bengaluru and Kolkata, Ministry of Earth Sciences Secretary M Rajeevan said on Monday.
He said that more cities are witnessing flooding because of urbanisation and chocking of drainage system.
The IMD has already developed a flood warning system for Mumbai and Chennai, Rajeevan said, adding the one for Mumbai was launched in June.
"We are also developing a similar system for Bengaluru and Kolkata," he said at a press briefing.
To a question on doppler radars, he said their numbers are being enhanced across the country. A radar is also coming up near Kannur airport in Kerala, Rajeevan added.
